AB  - In this paper, we have investigated one-step preparation of vanadium doped TiO2 coatings formed by plasma electrolytic oxidation (PEO) of titanium in electrolyte containing 10 g/L Na3PO4 center dot 12H(2)O + 0.5 g/L NH4VO3. The morphology, phase structure, and elemental composition of the formed coatings were characterized by atomic force microscopy (AFM), x-ray diffraction (XRD), and x-ray photoelectron spectroscopy (XPS) techniques. Ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS) was employed to evaluate the band gap energy of obtained coatings. Vanadium doped TiO2 coatings are partly crystallized and mainly composed of anatase phase TiO2, with up to about 2 wt% of vanadium present in the surface layer of the oxide. The valence band photoelectron spectra and UV-Vis DRS showed that vanadium doped TiO2 coatings exhibit notable red shift with respect to the pure TiO2 coatings. The photocatalytic activity was evaluated by monitoring the degradation of methyl orange under simulated sunlight conditions. Photocatalytic activity of vanadium doped TiO2 coatings increases with PEO time. Prolonged PEO times result in higher roughness of obtained coatings, thus increasing surface area available for methyl orange degradation. Vanadium doped TiO2 coatings obtained after 180 s of PEO time exhibit the best photocatalytic activity and about 67% of methyl orange is degraded after 12 h of irradiation under simulated sunlight.

AB  - In this study, we have shown that atomic force microscopy is a powerful technique to study the fractal parameters of TiO2/WO3 coatings prepared by plasma electrolytic oxidation (PEO) process. Since the surface roughness of obtained oxide coatings affects their physical properties, an accurate description of roughness parameters is highly desirable. The surface roughness, described by root mean squared and arithmetic average values, is analyzed considering the scans of a series of atomic force micrographs. The results show that the oxide coatings exhibit lower surface roughness in initial stage of PEO process. Also, the surfaces of TiO2/WO3 coatings exhibit fractal behavior. Positive correlation between the fractal dimension and surface roughness of the surfaces of TiO2/WO3 coatings in initial stage of PEO process was found.

AB  - Two series of polyurethane (PU) networks based on Boltorn (R) hyperbranched polyester (HBP) and hydroxyethoxy propyl terminated poly(dimethylsiloxane) (EO-PDMS) or hydroxy propyl terminated poly(dimethylsiloxane) (HP-PDMS), were synthesized. The effect of the type of soft PDMS segment on the properties of PUs was investigated by Fourier transform infrared spectroscopy (FTIR), contact angle measurements, surface free energy determination, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), atomic force microscopy (AFM), dynamic mechanical thermal analysis (DMTA) and differential scanning calorimetry (DSC). The surface characterization of PUs showed existence of slightly amphiphilic character and it revealed that PUs based on HP-PDMS have lower surface free energy, more hydrophobic surface and better waterproof performances than PUs based on EO-PDMS. PUs based on HP-PDMS had higher crosslinking density than PUs based on EO-PDMS. DSC and DMTA results revealed that these newly-synthesized PUs exhibit the glass transition temperatures of the soft and hard segments. DMTA, SEM and AFM results confirmed existence of microphase separated morphology. The results obtained in this work indicate that PU networks based on HBP and PDMS have improved surface and thermomechanical properties.

AB  - In this paper, we have investigated photocatalytic properties of TiO2/WO3 coatings formed by plasma electrolytic oxidation (PEO) of titanium in 12-tungstosilicic acid water solution and compared with photocatalytic activity of pure TiO2 coatings. The photocatalytic activity of the coatings is evaluated by measuring the degradation of methyl orange under simulated sunlight conditions. Photocatalytic activity of TiO2/WO3 coatings varied with duration of PEO process and higher photoactivity is obtained for a shorter process time. Photocatalytic activity of TiO2/WO3 coatings is related to morphology and phase and elemental composition of coatings. The oxide coatings morphology is strongly dependent on PEO time. The elemental components of the coatings are Ti, W and O. The oxide coatings are partly crystallized and mainly composed of WO3 and anatase. Decrease in the number of microdischarge channels and agglomeration of particles on the surface leads to a decrease in photocatalytic activity. The reduction of the photocatalytic activity with increased time of PEO process is accompanied with the increase of WO3 concentration on the coatings' surface. Diffuse reflectance spectroscopy has shown that coatings enriched with tungsten oxide exhibit significant red shift with respect to the pure TiO2 coatings. TiO2/WO3 coatings with improved catalytic activity, compared to pure TiO2 coatings, are grouped around energy band gap of 2.6 eV. The results of PL measurements of TiO2/WO3 coatings are in agreement with photocatalytic activities. The increase of PL intensity corresponds to decrease of photocatalytic activity of the coatings, indicating fast recombination of electron-hole pairs.

AB  - Two series of silver modified Ni-Mg materials were synthesized by precipitation-deposition on SiO2 support derived from two silica sources: diatomite activated at 800°C (Series a; Mg/Ni = 0.1 and SiO 2/Ni = 1.07) and synthetic water glass (Series b; Mg/Ni = 0.1 and SiO2/Ni = 1.15). The modification with silver was made at three molar Ag/Ni ratios, namely 0.0025, 0.025, and 0.1. The effects of the source of the silica support and the silver presence and content on the nickel state in the silver modified reduced-passivated NiMg/SiO2 precursors of the vegetable oil hydrogenation catalyst were established by X-ray diffraction and X-ray photoelectron spectroscopy techniques. The passivation procedure was applied in order to protect the metallic nickel particles from further oxidation. The crystallization of the formed nickel hydrosilicate phases depends on the source of the silica support, more expressed in the diatomite supported samples. It was shown that the silver modification of the NiMg/SiO2 precursors enhances the reduction of the nickel hydrosilicates accompanied by formation of relatively smaller metallic nickel particles, more pronounced in the water glass supported precursors. The increase of the silver content in the water glass deposited samples is responsible for the metallic nickel dispersion increase. The higher content of the Ni0 particles on the surface of the diatomite deposited samples is in accordance with the higher stability of the larger metallic nickel crystallites to oxidation during the passivation step. On contrary, higher dispersed Ni0 particles on the surface of the water glass supported samples are more susceptible to the oxida

AB  - The complete oxidation of n-hexane in air over a stainless steel foil (SS) coated with a thin film of ZrO2 (SS/ZrO2), SS/ZrO2/Pt, SS/ZrO2/La2O3/CuCo and SS/ZrO2/La2O3/CuCo/Pt catalysts has been investigated. The ZrO2 films were deposited on the SS substrate by electrochemical and spray pyrolysis (SP) methods. Among electrochemically prepared samples, Pt containing catalysts exhibited the highest activity. The presence of La, Cu and Co oxides along with Pt did not improve the catalytic activity. The SS/ZrO2/Pt sample prepared by spray pyrolysis showed a much better light-off characteristic than did the electrochemically obtained catalysts. The spray pyrolysis method permits the preparation of thicker ZrO2 films as compared to films prepared by an electrodeposition method. Thus, an increase of the surface area available for deposition of Pt atoms was achieved.

AB  - We have investigated the deposition of ZrO2 and Al2O3 films on a stainless steel (SS) substrate by spray pyrolysis method. The ZrO2 films were deposited from aqueous solution of zirconium dinitrate oxide. For Al2O3 films, a boehmite sol was used. The specific surface areas of samples were determined by the BET-method and sample surfaces were characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. The spray pyrolysis method permits the preparation of ZrO2 and Al2O3 thin films on SS with good adhesion. This method enables preparation of oxide layers with relatively high specific surface area, suitable for applications as catalysts supports.

AB  - The influence of low loadings of MnOx on the catalytic activity for n-hexene and CO oxidation over highly dispersed Pt on alumina catalysts has been investigated. The applied deposition-precipitation method allows Mn to be deposited on the Pt containing egg-shell volume. The catalyst samples were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and selective CO chemisorption. Platinum influences the dispersion of deposited MnOx. The dispersion of the MnOx phase is higher on Pt containing samples than on Al2O3. The Pt decoration by Mn is reflected by a low CO uptake and the Pt oxidation state (Pt2+). The addition of Mn lowers the catalytic activity for CO oxidation. This is attributed to a change of the Pt sites such that adsorption of CO is less favorable. The activity of the catalysts in the oxidation of n-hexane showed a significant improvement with addition of MnOx. A light-off shift by about 40 degrees C was observed. This improvement is attributed to the formation of Mn-Pt oxide like species that primarily weakens the Pt-O bond.
