AB  - The plasma electrolytic oxidation process of Ti foil in the presence of a colloidal solution of Ag nanoparticles was used for the synthesis of exceptionally photocatalytically active Ag-doped TiO2 coatings. UV–Vis absorption spectroscopy was applied to follow the changes in the surface plasmon resonance band of the Ag nanoparticles as a function of the Ag:PO43− ratio in a phosphate-based electrolyte solution. Transmission electron microscopy revealed the size of the Ag nanoparticles in the range of 3–12 nm. The XRD patterns of the Ag-doped TiO2 coatings confirmed the crystalline anatase TiO2 phase regardless of the dopant concentration and without metallic Ag or crystalline Ag oxide forms. The typical porous morphology of the Ag–TiO2 coatings was observed by scanning electron microscopy. A significantly improved photocatalytic activity of the Ag–TiO2 coatings in the degradation process of the insecticide lindane (gamma isomer of benzene hexachloride) and test molecule methyl orange compared to pure TiO2 was determined using the GC technique. The degradation efficiency of Ag-doped TiO2 coatings is higher for lindane than for methyl orange.

AB  - Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals with extremely strong C-F bonds. Due to their thermal stability, acid resistance, and high surface activity, they have been widely used for several decades in various consumer products. PFAS has been detected in water, soil, sediment, air, food, and biota samples on all continents and due to this are recognized as environmental and human health risk (Carlson et al. 2022). In the last decade, several available technologies were tested for the remediation of PFAS-polluted environments, such as adsorption, filtration, thermal destruction, oxidation/reduction, and soil washing, but several disadvantages were reported (Bolan et al., 2021). We hypothesize that by using advanced oxidation techniques followed by microbial treatment decrease in the concentration of PFOA as a PFAS model compound will occur. In the beginning, we tested separately abiotic and biotic degradation of PFOA. Target LC-MS/MS was used for quantitative analysis of PFOA decrease, and for detecting degradation products, nontargeted LC-MS/MS analysis was used.  In the photocatalysis study, we used selected Ti and Al-based photocatalysts. The experiments were conducted at 20 °C in an open cylindrical polypropylene reactor, and a simulated solar radiation lamp (Solimed BH Quarzlampen) was used as a light source. Microbial communities were isolated from the locations in Serbia, Japan, and Italy known for their pollution with PFAS, and enrichment was conducted on the media supplemented with ppm values of PFOA (Beskoski et al., 2018). Microbial communities were used as inoculum in the PFOA biodegradation study.

AB  - Ta2O5 coatings were created using micro-arc discharges (MDs) during anodization on a tantalum substrate in a sodium phosphate electrolyte (10 g/L Na3PO4·10H2O). During the process, the size of MDs increases while the number of MDs decreases. The elements and their ionization states present in MDs were identified using optical emission spectroscopy. The hydrogen Balmer line Hβ shape analysis revealed the presence of two types of MDs, with estimated electron number densities of around 1.1 × 1021 m−3 and 7.3 × 1021 m−3. The effect of MDs duration on surface morphology, phase and chemical composition, optical absorption, and photoluminescent, properties of Ta2O5 coatings, as well as their applications in photocatalytic degradation of methyl orange, were investigated. The created coatings were crystalline and were primarily composed of Ta2O5 orthorhombic phase. Since Ta2O5 coatings feature strong absorption in the ultraviolet light region below 320 nm, their photocatalytic activity is very high and increases with the time of the MDs process. This was associated with an increase of oxygen vacancy defects in coatings formed during the MDs, which was confirmed by photoluminescent measurements. The photocatalytic activity after 8 h of irradiation was around 69%, 74%, 80%, and 88% for Ta2O5 coatings created after 3 min, 5 min, 10 min, and 15 min, respectively.

AB  - In this work, it was shown that TiO2/Al2TiO5 coatings obtained by plasma electrolytic oxidation of titanium in alkaline electrolyte with added NaAlO2 show significantly better photocatalytic activity (PA) in degradation of methyl orange under simulated sunlight than anatase TiO2 coatings obtained in pure alkaline electrolyte. The TiO2/Al2TiO5 coating with the highest PA was obtained in alkaline electrolyte with the addition of 2.0 g/L NaAlO2, which has approximately 2.4 higher PA than anatase TiO2. Photoluminescence indicates that increased PA of TiO2/Al2TiO5 coatings is associated with increased number of oxygen vacancy and other defects.

AB  - In this report, magnetic porous polymer functionalized with pentaethylenehexamine (mP-PEHA) was tested as CO2 sorbent. The sorbent mP-PEHA was characterized by Fourier transform infrared spectroscopy in ATR mode (FTIR-ATR), scanning electron microscopy (SEM) and mercury porosimetry. CO2 adsorption was determined using a pulse gas chromatographic method. At optimal adsorption conditions (20 °C), the CO2 sorption capacity reached 10.8 ml CO2/g (0.48 mmol CO2/g). Temperature-programmed desorption (TPD) experiments were conducted to calculate the activation energy of CO2 desorption. Low activation energy (18.34 kJ/mol) and high desorption rate, with a stable uptake in five adsorption/desorption cycles, suggest mP-PEHA as potentially excellent sorbent for CO2 absorption.

AB  - Spray pyrolysis was used to deposit CeO2–TiO2 coatings on stainless steel substrates. The addition of CeO2 to TiO2 changes morphology of the coatings, causing the surface to become laced and some CeO2 ions are incorporated into TiO2 crystal lattice. Part of CeO2 is highly dispersed on the surface of TiO2. The XPS showed the simultaneous existence of Ce4+ and Ce3+ on coating surface. As the CeO2 content in composites increases from 0.5 to 20%, the band gap decreases from 3.16 to 2.88 eV, respectively. The photoactivities in the degradation of methyl orange and lindane were significantly influenced by the content of Ce in composite. For methyl orange photodegradation, the highest activity had coating with CeO2 content of 2 wt%. In contrast, the activity of coatings in lindane photodegradation gradually decreases as the CeO2 content increases. However, efficiency of CeO2–TiO2 coatings remained satisfactory for application in process of lindane degradation. Lindane conversion at 6 h of irradiation is in the range from 88% for pure TiO2 to 60% for CeO2–TiO2 coating with CeO2 content of 20 wt%. Photodegradation of lindane was enhanced on pure TiO2 sites, while methyl orange degradation is highest on composite CeO2/TiO2 species with CeO2 content of 2 wt%.

AB  - The effect of selected transition metals (Mn, Ni, Co) modified TiO2 coatings formed by plasma electrolytic oxidation of titanium on their surface morphology, phase and chemical composition, optical absorption, and photocatalytic degradation of methyl orange (MO) was investigated. Coatings were formed in an alkaline electrolyte with varying concentrations of MnO, NiO, or Co3O4 powders. The morphology, thickness and phase structure of all formed coatings are nearly identical and independent of the content of transition metal ions embedded in TiO2. The X-ray diffraction and X-ray photoelectron spectroscopy results indicated that anatase TiO2 coatings were loaded with MnO, NiO, or Co3O4 from electrolytes. When up to 2.0 g/L of MnO, NiO, or Co3O4 is added to the electrolyte, the photocatalytic activity (PA) of the forming coatings is higher than for pure TiO2. The coatings formed in electrolyte with the addition of 0.75 g/L MnO, 1.5 g/L NiO, or 2.0 g/L Co3O4 had the highest PA. Increased PA is associated with a decrease in photogenerated electron/hole recombination rate, according to UV–Vis diffuse reflectance spectroscopy and photoluminescence measurements.

AB  - Anatase TiO2 coatings modified by Sb2O3 particles were formed by plasma electrolytic oxidation of titanium in 10 g/L Na3PO4⋅10H2O with addition of Sb2O3 particles. The photodegradation of methyl orange under simulated sunlight was used to probe the photocatalytic potential of TiO2/Sb2O3 coatings. The photocatalytic activity (PA) of obtained coatings is higher than pure TiO2 for adding up to 2.0 g/L of Sb2O3 particles to electrolyte. The highest PA was observed for coatings formed in electrolyte with the addition of 0.75 g/L Sb2O3. Increased PA is related to a decrease of photogenerated electron/hole recombination rate as a result of TiO2 and Sb2O3 coupling.

AB  - TiO2 coatings modified by Bi2O3 particles were successfully formed by plasma electrolytic oxidation (PEO) process of titanium in supporting electrolyte (10 g/L Na3PO4·10H2O) with the addition of Bi2O3 particles. The morphology, crystal structure, chemical composition, and optical properties of formed PEO coatings were investigated by scanning electron microscopy, energy-dispersive spectroscopy, X-ray fluorescence, X-ray diffraction, X-ray photoelectron spectroscopy, UV–Vis diffuse reflectance spectroscopy, and photoluminescent techniques. The photodegradation of methyl orange under simulated sunlight condition was used to determine the potential of TiO2/Bi2O3 coatings in photocatalysis. The photocatalytic activity (PA) of TiO2/Bi2O3 coatings is higher than that of pure TiO2. PA of TiO2/Bi2O3 coatings is highly dependent on the amount of Bi2O3 particles in the supporting electrolyte and the highest PA was observed for TiO2/Bi2O3 coating formed in supporting electrolyte with the addition of 1.2 g/L of Bi2O3 particles. Enhanced PA is related to the reduction of photo-generated electron/hole recombination rate as a result of TiO2 and Bi2O3 coupling.

AB  - The synthesis of Eu3+-doped MgAl oxide coatings containing MgO and MgAl2O4 was accomplished through plasma electrolytic oxidation of AZ31 magnesium alloy in aluminate electrolyte with the addition of Eu2O3 particles in various concentrations. Their morphological, structural, and above all, photoluminescent (PL) and photocatalytic activity (PA) were thoroughly investigated. PL emission spectra of MgAl oxide coatings feature characteristic emission peaks, which are ascribed to f–f transitions of Eu3+ ions from excited level 5D0 to lower levels 7FJ. The charge transfer state of Eu3+ or direct excitation of the Eu3+ ground state 7F0 into higher levels of the 4f-manifold are both attributed to the PL peaks that appear in the excitation PL spectra of the obtained coatings. The fact that the transition 5D0 → 7F2 (electrical dipole transition) in Eu3+-doped MgAl oxide coatings is considerably stronger than the transition 5D0 → 7F1 (magnetic dipole transition) indicates that Eu3+ ions occupied sites with non-inversion symmetry. Because of oxygen vacancy formation, the Eu3+-doped MgAl oxide coatings had a higher PA in the degradation of methyl orange than the pure MgAl oxide coating. The highest PA was found in Eu3+-doped MgAl oxide coating formed in an aluminate electrolyte with 4 g/L of Eu2O3 particles. The PA, morphology, and phase of Eu3+-doped MgAl oxide coatings did not change after several consecutive runs, indicating outstanding stability of these photocatalysts.

AB  - MgAl and MgAl/ZnO coatings were prepared by plasma electrolytic oxidation (PEO) of AZ31 magnesium alloy in aluminate electrolyte (5 g/L NaAlO2) without and with addition of ZnO particles in various concentrations. The MgAl coating was partially crystallized and contained MgO and MgAl2O4 phases. The addition of ZnO particles to aluminate electrolyte had no significant effect on the surface morphology of formed coatings, while the Zn content increased with ZnO particle concentrations. X-ray diffraction confirmed the incorporation of ZnO particles in the coatings. The photodegradation of methyl orange (10 cm3 of 8 mg/L) was used to measure the photocatalytic activity (PA) of MgAl and MgAl/ZnO coatings. The PA of MgAl coating after 8 h of irradiation was around 58%, while the PA of MgAl/ZnO coatings formed in aluminate electrolyte with the addition of ZnO particles in concentrations of 4 g/L, 8 g/L, and 12 g/L were around 69%, 86%, and 97%, respectively.

AB  - Introduction and study objectives: Lindane is a generic name for γ-hexachlorocyclohexane, one of the isomers from the group of Hexachlorocyclohexanes (HCH) [1]. Due to its neurotoxic activity, it had a very wide application, from agricultural to non-agricultural purposes. As a result of its lipophility, lindane can easily pass through the blood-brain barrier. The reason of his neurotoxicity is that it can interact with GABAA receptors and obstruct GABA neurotransmitter signaling in nervous system. People who have been exposed to lindane for a long time can experience serious health problems, such as: poor liver function, cardiac arrhythmias, and irregular menstruation. Due to its adverse health effect, lindane is classified as a “pregnancy category C” chemical [2]. It is also one of the Persistent Organic Pollutants (POPs) that were listed under the Annex A (elimination) of the Stockholm Convention with a specific exemption for use as a human health pharmaceutical [3]. The aim of this paper was the assessment of the immobilized titanium dioxide photocalytic properties in lindane degradation. Methodology: Spray pyrolysis method was used for a synthesis of thin titanium oxide films on the foils of the stainless steel [4]. The lindane solution was incubated with TiO2 and exposed to UV/VIS light. Aliquots were taken from the reaction mixture after 0, 2, 4, 6, 8, 10 and 12 hours. Lindane was extracted according to the EPA method 505 [5], and analyzed using an Agilent 7890A gas chromatograph (GC) connected to an electron capture detector (ECD). The GC was equipped with a Thermo Scientific™ TraceGOLD™ TG-5MT capillary column (60 m × 0.25 mm ID × 0.25 μm). The temperature program used for gas chromatography was: Initial heating temperature: 50 °C for 3 minutes, then heating at a rate of 30 °C/min to 210 °C for 20 minutes. Hydrogen with a flow rate of 60 mL/min was used as the carrier gas. Results and conclusions: Photoactivity of immobilized titanium dioxide in the degradation of lindane was measured as a percentage of lindane’s degradation compared to its initial concentration. The obtained results demonstrated that after two hours 45.32 % of lindane was degraded, while after twelve hours the percentage of degradation increased to 98.20 %. In this study we proved that the immobilized titanium dioxide can be used as a productive and fast photocatalyst for lindane photodegradation.

AB  - This paper presents a new two-step method for the synthesis of NiO/TiO2–CeO2 semiconductors, which implies, the first, the mechanochemical synthesis of TiO2–CeO2 support, and the second is the doping of different NiO contents by chemical precipitation in an aqueous medium in an ambient atmosphere. Structural, optical, electrochemical and photocatalytic properties of NiO/TiO2–CeO2 semiconductors were examined. The influence of different NiO contents on the electrocatalytic activity of NiO/TiO2–CeO2 samples was investigated in the oxygen evolution reaction and the results showed that the samples with the lowest NiO content have the highest electroactivity. The photocatalytic activity was determined during the phenol decomposition process over the samples with different NiO:TiO2–CeO2 ratios and the best photocatalytic activity is observed for the sample with 4.1 mol% NiO. The sample with the lowest NiO content obtained by a relatively simple method is suitable for use both as an electrode material in the oxygen evolution reaction and as a photocatalyst in the phenol decomposition process.

abstract = "This paper presents a new two-step method for the synthesis of NiO/TiO2–CeO2 semiconductors, which implies, the first, the mechanochemical synthesis of TiO2–CeO2 support, and the second is the doping of different NiO contents by chemical precipitation in an aqueous medium in an ambient atmosphere. Structural, optical, electrochemical and photocatalytic properties of NiO/TiO2–CeO2 semiconductors were examined. The influence of different NiO contents on the electrocatalytic activity of NiO/TiO2–CeO2 samples was investigated in the oxygen evolution reaction and the results showed that the samples with the lowest NiO content have the highest electroactivity. The photocatalytic activity was determined during the phenol decomposition process over the samples with different NiO:TiO2–CeO2 ratios and the best photocatalytic activity is observed for the sample with 4.1 mol% NiO. The sample with the lowest NiO content obtained by a relatively simple method is suitable for use both as an electrode material in the oxygen evolution reaction and as a photocatalyst in the phenol decomposition process.",

AB  - The LaTi0.4Mg0.4Fe0.2O3 perovskite was synthesized using a mechanochemical process followed by high-temperature annealing at 600 and 800 ​°C. The effects of milling time and annealing temperature on structural, microstructural changes and optical properties were examined. The photocatalytic activity of LaTi0.4Mg0.4Fe0.2O3 perovskite was evaluated through the photodegradation of methyl orange and methylene blue dyes under UV light irradiation. The results showed that the annealing temperature performed an important role in the crystallite size, crystalline degree, photoluminescence, and band gaps of the LaTi0.4Mg0.4Fe0.2O3 samples. The temperature of annealing had a profound influence on the photocatalytic activities of the LaTi0.4Mg0.4Fe0.2O3 perovskite in the single and binary dye system. The highest photocatalytic activity for methyl orange degradation showed the LaTi0.4Mg0.4Fe0.2O3 annealed at 800 ​°C, while not annealed sample, show the highest activity for degradation of methylene blue. The maximum efficiency of methylene blue photodegradation in individual and binary mixtures was observed over non-annealed perovskite at the same irradiation times. The photodegradation of methylene blue and methyl orange on the LaTi0.4Mg0.4Fe0.2O3 followed a pseudo-first-order kinetic process.

AB  - This paper presents a new method for improvement of ultraviolet light driven photocatalytic activity of ZnO by immobilizing ZnO particles into Al2O3:Ce3+ coatings which emit intense radiation in the near ultraviolet region when excited by middle ultraviolet radiation. When Al2O3:Ce3+/ZnO coatings are illuminated by ultraviolet light in photocatalytic reactor, emitted ultraviolet radiation originating from Ce3+ ions synergistically participates in photocatalytic reactions on ZnO. Al2O3:Ce3+/ZnO coatings were formed by plasma electrolytic oxidation of
aluminum in electrolyte containing 2 g/L of ZnO particles and up to 8 g/L of CeO2 particles. Structural, optical, photoluminescent, and photocatalytic properties of formed surface coatings were examined. All formed coatings feature virtually the same thickness, morphology, phase composition, and absorption properties. Concentration of incorporated Ce3+ ions into Al2O3 host and concentration of immobilized ZnO particles are the only parameters by which the coatings differ from each other resulting in difference in photocatalytic activity. Al2O3:Ce3+/ZnO coatings show better photodegradation of methyl orange with respect to Al2O3/ZnO coatings. The best photocatalytic activity is observed for the coating formed in electrolyte containing 4 g/L of CeO2 particles.

AB  - The spray pyrolysis is fast and simple method for deposition of CeO2 – rutile TiO2 coatings on stainless steel substrate. The coatings were deposited on stainless steel substrate and characterized by XRD, AFM, XPS, Raman, DRS and photoactivity test for methyl orange decolorization. Photoactivity of CeO2 – rutile TiO2 coatings increase with increasing CeO2 content up to 5 wt% and further increase of CeO2 content leads to decrease of photoactivity. Improvements of photoactivity originate from close contact between CeO2 and rutile TiO2 particles which create numerous centers able to produce very reactive radical species. Besides, the close contact between the CeO2 and rutile TiO2 provides easier charge transfer facilitating the formation of electron/hole pairs that is a necessary step in the overall photocatalytic process.

AB  - TiO2-CeO2 nanopowders were synthesised by a ball-milling process and then annealed at temperatures from 500 degrees to 800 degrees C. X-ray diffraction and diffuse reflectance spectra were used in combination with temperature programmed desorption to determine the structural and microstructural changes of nanopowders as a the function of annealing temperature. The results of the X-ray analysis showed that the weight fraction of the cerianite phase remained unchanged with a temperature rise of 600-700 degrees C, indicating that the phase changes occur only within TiO2. The TiO2-CeO2 nanopowder showed enhanced optical properties with a red shift after the thermal treatment. Photocatalytic studies revealed that the sample annealed at 600 degrees C showed higher photocatalytic activity than samples annealed at lower or higher temperatures in the degradation of the methyl orange. The activity test of all samples is in accordance with photoluminescence measurements, proportional to the concentrations of hydroxyl radicals at the photocatalyst surfaces.

AB  - Tb doped TiO2 coatings are formed by plasma electrolytic oxidation (PEO) of titanium in water solution of 10 g/L Na3PO4.12H(2)O with addition of Tb4O7 powder. Surface morphology, chemical, and phase composition of obtained PEO coatings are investigated utilizing scanning electron microscopy equipped with energy dispersive x-ray spectroscopy and X-ray diffraction. Uniformly distributed Ti, O, P, and Tb are identified as the main constituents of the coatings. Diffraction patterns of obtained coatings show well pronounced reflections inherent to anatase phase of TiO2. Performed photoluminescence measurements indicate that incorporated Tb is in trivalent oxidation state. Photoluminescence emission spectra feature two overlapping regions: the first region is related to band of TiO2 host and the second region which features several emission bands is ascribed to f-f transitions of Tb3+ from excited level D-5(4) to lower levels F-7(J) (J = 3,4,5, and 6). The photocatalytic activity (PA) of Tb3+ doped TiO2 coatings is probed by measuring the photodegradation of methyl orange under simulated sunlight conditions, suggesting that the main factor affecting PA is concentration of Tb3+ ions incorporated into coatings. Tb3+ doped TiO2 coatings formed for short time have better PA than pure TiO2 coatings formed under the same conditions; the highest PA is observed for the coating formed after 1 min of PEO process. Presence of Tb3+ ions into TiO2 coatings in small concentration improves PA through effective suppression of electron/hole recombination.

The photocatalytic activity (PA) of Tb3+ doped TiO2 coatings is probed by measuring the photodegradation of methyl orange under simulated sunlight conditions, suggesting that the main factor affecting PA is concentration of Tb3+ ions incorporated into coatings. Tb3+ doped TiO2 coatings formed for short time have better PA than pure TiO2 coatings formed under the same conditions; the highest PA is observed for the coating formed after 1 min of PEO process. Presence of Tb3+ ions into TiO2 coatings in small concentration improves PA through effective suppression of electron/hole recombination.",

AB  - This paper presents the results of our recent investigation focused on the preparation and possible photocatalytic application of iron doped TiO2 coatings formed by plasma electrolytic oxidation of high purity titanium in electrolyte containing FeSO4. The morphology, phase and elemental composition, and absorption band of the coatings were characterized by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and diffuse reflectance spectroscopy. The photocatalytic activity of coatings was evaluated by measuring the degradation of methyl orange under simulated sunlight conditions. It was found that the addition of iron precursor to electrolyte solution improves the photocatalytic properties of obtained coatings with respect to pure TiO2 coating. The incorporation of iron in TiO2 lattice was identified as the main factor affecting the increase of photocatalytic activity. The highest photocatalytic activity was observed when coatings were processed for 2 min with addition of 1 g/L FeSO4 to electrolyte.

AB  - In this study, WO3 doped TiO2 powders were synthesized via sol-gel method combined with a hydrothermal process. The effect of sintering temperature on mesoporous structure and catalytic activities of these powders were investigated. The physical analysis via X-ray diffraction indicates that prepared samples are a mixture of anatase and rutile TiO2 phases. X-ray peak analysis is used to evaluate the crystallite size and lattice strain by the Williamson-Hall analysis. Considering all the reflections of the anatase phase the lattice strain ranging from c = 9.505 to c = 9.548 is calculated, suggesting that microstrain decreases when calcination temperature increases. N-2 adsorption-desorption analysis shows that the surface area and pore volume decrease with increasing temperature and that WOx-TiO2 powders primarily consist of mesopores. Sintering temperature induced a change in textural properties causing a systematic shift towards larger mesopores. Simultaneously, photoactivity in decolorization of methyl orange increases with increasing calcination temperature up to 700 degrees C, followed by significant decrease with its further increase.

AB  - CdS particles modified anatase TiO2 photocatalysts were formed on titanium substrate by plasma electrolytic oxidation for 2 min in supporting electrolyte (10 g/L Na-3 center dot PO4 center dot 12H(2)O) with addition of CdS particles in concentrations up to 8 g/L. Content of CdS particles incorporated into TiO2 coatings depends of CdS particles concentration in supporting electrolyte, while surface morphology, phase structure and absorption properties of formed coatings were not significantly influenced by the addition of CdS particles. In contrast to pure TiO2 coatings, TiO2/CdS coatings exhibit enhanced photocatalytic activity (PA) in the degradation of methyl orange, used as a model organic pollutant, under simulated solar irradiation. The highest PA was observed for TiO2/CdS coating formed in supporting electrolyte with addition of 0.4 g/L of CdS particles. Photoluminescence measurements indicate that enhanced PA is related to the reduction of the recombination rate of photogenerated electron/hole pairs as a result of TiO2 and CdS coupling.

AB  - Nanocrystalline TiO2-CeO2 powders were synthesized from their TiO2 and CeO2 oxides using mechanical ball milling process. The response surface method is applied to identify optimal parameters for the synthesis of TiO2-CeO2 photocatalyst. Analysis of variance and main effect plot are used to determine the significant parameters and set the optimal level for each parameter. Regression analysis showed good agreement of experimental data with the second-order polynomial model with a coefficients of determination: R-2 = 0.991, R-Adj(2). = 0.940 and R-Pred(2). = 0.983. Under optimal experimental conditions of TiO2:CeO2 weight percentage ratio 71: 29, milling speed 200 rpm, and milling time 115 min the highest photodegradation efficiency was achieved. On the basis of the above statistical analysis, it was found that the band gap energy of TiO2-CeO2 nanoparticles decreases with the increase of the milling speed and milling time with constant TiO2:CeO2 weight percentage ratio. Obtained results suggest that mechanical ball milling process is a rapid, efficient and low energy consumption method to synthesize TiO2-CeO2 photocatalyst.

AB  - This article presents the comparison of structural and fractal properties of nanocrystalline titanium dioxide (TiO2) and TiO2 modified with tungstophosphoric acid (TiO2/HPW) and their impact on the photocatalytic degradation of hazardous water pollutants. TiO2 and TiO2/HPW samples were synthesized by a combined solgel and hydrothermal processing. The XRD analysis of pure TiO2 samples revealed that phase composition was mainly dependent on the calcination temperature, changing from amorphous TiO2 to crystalline anatase and rutile by increasing the temperature. On the other hand, the XRD of TiO2/HPW samples calcined at temperatures above 600 degrees C showed crystalline peaks associated to formation of WO3 and WO2.92 crystalline domains. The N-2 adsorption-desorption isotherm and pore size distribution of TiO2/HPW samples detected the existence of mesoporous characteristic with very narrow bimodal pores in the mesoporous region. The structural heterogeneity of samples was analyzed by means of pore size distribution functions, while the variation in fractal dimension were determined from the nitrogen adsorption isotherms, using the modified Frenkel-Halsey-Hill method. The results demonstrate that the approach is capable of characterizing complex textures such as those present in the TiO2 and TiO2/HPW photocatalysts. Besides, the effect of calcinations condition on photocatalytic properties of the samples was also investigated. The highest efficiency with respect to methyl orange photodecomposition was observed for TiO2/HPW photocatalysts calcined at 700 degrees C.
