AB  - Five NiO/TiO2 materials with a different mass ratiо оf NiO tо TiO2 (3.3, 6.7, 16.3, 23.7, and 36.8%) were synthesized by wet impregnation process and characterized by DR UV-vis, scanning electrоn micrоscоpe, transmissiоn electrоn micrоscоpy, X-ray diffractiоn methоd, N2 physisorption, and temperature-programmed reduction. The characterizatiоn confirmed the existence of nano-sized cubic NiO on the commercial TiО2. The оbserved interactiоn between TiO2 and NiО phases confirmed that the оbtained material dоes nоt constitute a physical mixture оf twо species. The photocatalytic hydrоgen generatiоn efficiency [mоnitored by gas chromatography–thermal conductivity detector (GC-TCD)] of these materials from methanol-water mixtures under simulated solar radiation and artificial UV radiation was investigated. For some synthesized NiO/TiO2 materials, higher photocatalytic efficiency was found compared with the commercial TiO2 Degussa P25 catalyst. Also, the obtained results showed that 0.125 g L−1 of 6.7%NiO/TiO2 and 5% (v/v) of methanol were the optimal operating parameters. Furthermоre, fоr the mоst efficient phоtоcatalytic system under the influence оf simulated solar radiation, a 1.8 times higher hydrоgen prоduction rate was achieved cоmpared tо that under the influence оf artificial UV radiatiоn.

AB  - Mesoporous anatase nanopowders were doped with 0.05−0.5 mol% of W6+, in order to obtain more efficient photocatalyst than TiO2 Degussa P25 in the degradation of amitriptyline (AMI) under simulated solar irradiation (SSI). Dominant XRPD peaks were ascribed to anatase phase, with additional peaks which could correspond to brookite, TiO2 bronze and sodium titanate, Na2Ti9O19. The Raman scattering measurements have confirmed anatase as dominant phase, with broad Raman feature at ~270 cm−1 possibly related to Ti–O–Na stretching vibration. All W-doped nanopowders have shown enhanced adsorption and higher efficiency in photodegradation of AMI in comparison to TiO2 Degussa P25 under the same conditions. The catalyst doped with 0.4 mol% of W6+, which has shown the highest efficiency in degradation of AMI under SSI, has
also been tested in degradation of alprazolam (ALP). The effect of substrate type (AMI and ALP), catalyst loading, and initial substrate concentration on photocatalytic degradation using SSI was examined. The identification of the species responsible for the photocatalytic degradation of AMI and ALP by the catalyst doped with 0.4 mol% of W6+ was performed in the presence of various scavengers under SSI. The major role in degradation of AMI may be attributed to hydroxyl radicals, whereas superoxide anion radicals, singlet molecular oxygen and hydroxyl radicals contribute to degradation of ALP.

AB  - This work presents the characterization of novel synthesized WO3/Fe3O4 catalysts and investigates their photocatalytic activity for thiacloprid decomposition under UV and simulated sunlight radiation. Four WO3/Fe3O4 nanopowders with different amounts of WO3 were synthesized by chemical co-precipitation method. XRD analysis showed the presence of hematite and magnetite nano-dimensional phases of Fe3O4 in the catalysts. The magnetite phase content increased with increasing WO3 content. Degradation efficiency of thiacloprid in the presence of 6.1WO3/Fe3O4/H2O2 under simulated solar radiation was 2.2 times higher compared to Fe3O4. Under an external magnetic field, a significant increase in the catalysts separation from reaction mixture was observed.

AB  - Efficiency of heterogeneous photocatalytic degradation of aiprazolam was investigated. The structural and morphological properties of ZnO were investigated in detail. It was found that ZnO has wurtzite structure with crystallite size about 41 nm, specific surface area about 6.5 m(2)/g, and intraparticle system of pores (maximum pore width about 160 nm). The efficiency of aiprazolam photocatalytic degradation was examined as a function of the type of irradiation (UVA, visible, and simulated solar irradiation) and photocatalyst (ZnO, TiO2 Degussa P25), photocatalyst loading, pH, and the presence of hydroxyl radical, and positive hole scavengers. By examining the effect of types of irradiation and catalysts, it was found that the UVA/ZnO system is the most efficient for alprazolam removal. The optimum catalyst loading was 2.0 mg/mL for TiO2 Degussa P25, while in presence of ZnO degradation rate increases in whole investigated range. In the case of ZnO, the pH 7 was selected as an optimal condition, while in aqueous suspension of TiO2 Degussa P25, degradation rate increases in whole investigated pH range (3.4-8.8), but increasing is not as pronounced as in case of ZnO. Also, it was found that ZnO photocatalysis takes place only via hydroxyl radicals, while using TiO2 Degussa P25 positive holes play significant role, too. The results of total organic carbon and ionic chromatography analysis showed that after 60 min of irradiation using both catalysts aiprazolam was completely mineralized. Here, for the first time, reaction intermediates formed using both catalysts were studied in detail, whereby the main intermediates were hydroxyl derivates. ZnO showed high stability in photodegradation after three successive runs.

AB  - This article is concerned with the kinetics of the photocatalytic degradation of four neonicotinoids insecticides as active ingredients (AN) in their commercial formulations by using the annular slurry reactor (ASR). For all Als, more effective photodegradation was achieved by UVA than by visible light irradiation. The most efficient degradation was observed in the case of thiacloprid, which degraded completely after two hours of irradiation using UVA, and 59% using visible light irradiation. On the other hand, the most stable appeared to be acetamiprid, whereby during the same time of irradiation it was degraded 42% using UVA, and only 4% using visible light irradiation. Because of that the efficiency of a number of advanced oxidation processes was examined in the case of acetamiprid. It was found that the presence of H2O2 in ZnO, 7.8Fe/ZnO, and 7.2Fe/TiO2 systems using UVA did not bring significant changes in the efficiency of degradation. However, using visible light irradiation the presence of H2O2 in ZnO and 7.8Fe/ZnO systems significantly increases efficiency of acetamiprid degradation. Also, by adjusting pH to 2.80 in the system 7.2Fe/TiO2/H2O2 using both type of irradiation resulted in a significant increase of the degradation efficiency. For the first time, for ZnO/H2O2 system a general reaction mechanism in the dark, as well as in the presence of visible light irradiation was proposed. The electrical energy consumption of ASR was estimated for the most efficient visible light irradiation system using the figure-of-merit electrical energy per order and compared with batch and laminar falling film slurry reactor.

AB  - Two series of nanocrystalline brookite-type powders have been synthesized by using combined sal gel hydrothermal method with titanium tetrachloride (TiCI4) as a precursor and hydrothermal temperature and reaction time varied in the range of 120-200 degrees C and 12-48 h, respectively. The effects of chosen synthesis parameters on structural, morphological and optical properties of synthesized powders have been investigated by the XRPD, SEM, EDS and BET measurements, as well Raman spectroscopy and spectroscopic ellipsometry. The XRPD results have shown that pure brookite phase, with mean crystallite size of -33 nm, has been obtained only in the sample synthesized at 200 degrees C, after 24 h of hydrothermal process. In all other samples anatase phase also appears, whereas rutile and sodium titanate phases have been noticed in the samples synthesized at lower temperatures. The presence of different titania phases has also been confirmed and analyzed by Raman scattering measurements. The SEM measurements have shown spindle-like particles in brookite-rich samples synthesized at 200 degrees C, whereas BET measurements have detected mesoporous structure in these samples. The properties of synthesized powders have been correlated to their photocatalytic efficiency, tested in degradation of alprazolam, one of the 5th generation benzodiazepines. The sample consisted of pure brookite has shown the highest efficiency in the photodegradation of alprazolam, practically equal to the activity of Degussa P25.

AB  - This contribution is concerned with the comparison of the efficiency of the removal of four pure neonicotinoid active ingredients (AIs) and their commercial formulations (CFs) from aqueous solutions by using different advanced oxidation processes at the pH 2.8. The AIs of thiamethoxam and imidacloprid, and their CFs (Actara and Confidor), having a nitroguanidine functional group, exhibited low persistence to photolysis. In contrast to them, thiacloprid and acetamiprid and their CFs (Calypso and Mospilan), containing a cyanoimine functional group, were stable during the UV irradiation period. As expected, the degradation rate of the studied neonicotinoids increased significantly in the combined action of UV radiation and H2O2. In the case of thiacloprid and acetamiprid and their CFs, the reaction of the OH radicals formed and molecules of these insecticides was the major destruction pathway. The increased photodegradation efficiency of the UV/7.2Fe/TiO2/H2O2 and vis/7.2Fe/TiO2/H2O2 processes was attributed to the surface photoreduction of Fe3+ to Fe2+, which produces new OH radicals in the reaction with H2O2. In the presence of visible light, the efficiency may be partly due to the formation of the H2O2-TiO2 complexes. For the 7.2Fe/TiO2/H2O2 process in the presence of UV or visible radiation, no significant influence on the efficiency of photodegradation was observed in dependence of the structural differences of selected neonicotinoids. These results strongly suggest that highly reactive hydroxyl radicals, generated on the catalyst's surface in the reaction involving H2O2, are responsible for this oxidation. In order to investigate degree of mineralization for all insecticides, TOC measurements were also conducted. Also, it was observed that the removal of pure AIs and their CFs by dark adsorption was almost negligible.

AB  - The possibility of the use of the laminar falling film slurry type photoreactor was examined in conjunction with ZnO as a photocatalyst for the removal of thiacloprid (TCL) from Calypso 480-SC commercial formulation by UV radiation. The degradation kinetics were monitored by HPLC DAD, while the disappearance of the nitrile group, i.e. TCL and intermediates containing this group, was followed by FTIR The study of TCL removal under different operating conditions indicated that 2 g/L of ZnO was an optimal catalyst loading, and the optimal pH was 6.8. In the investigated range of initial concentrations of TCL (0.05-0.38 mM), the photocatalytic degradation in the first stage of the reaction followed approximately a pseudo-first-order kinetics. The increase of LTV-light intensity resulted in a linear increase in the rate of TCL degradation. The figure-of-merit electrical energy per order was employed to estimate the electrical energy consumption. Because the efficiency of TCL photodegradation in the natural thermal water was about two times lower than in distilled water, the investigation encompassed the influence of the thermal water components, i.e. different inorganic ions and humic acid, on the rate of TCL degradation.

AB  - Three Fe/TiO2 photocatalysts with different content of Fe (1.9, 7.2 and 13.9%, w/w) were synthesized by a simple deposition-precipitation method and characterized by XRD, SEM, N-2 physisorption at 77K and Mossbauer spectroscopy. The characterization showed the presence of nano-sized Fe2O3 particles (less than 4 nm) on the TiO2 support. The photocatalytic efficiency of the catalysts was examined on the example of thiacloprid (TCL) degradation under UV light irradiation in aqueous suspension in the presence/absence of H2O2. Since the efficiency of TCL degradation in the presence of H2O2 (heterogeneous photo-Fenton process) was more than two times higher, all other investigations were conducted in the presence of H2O2. The photocatalyst with 7.2%, w/w Fe (denoted as 7.2Fe/TiO2) appeared to be most efficient. The photocatalytic degradation studied under different operating conditions indicated that 0.5 g L-1 of 7.2Fe/TiO2 was an optimal catalyst loading, and the optimal pH was 2.8. In the investigated range of initial concentrations of TCL (0.06-0.32 mM) the photocatalytic degradation in the first stage of the reaction followed approximately a pseudo-first order kinetics. The suspended Fe/TiO2 spontaneously precipitated once the stirring of the reaction mixture was terminated (>90% after 15 min). The results clearly demonstrated that 7.2Fe/TiO2 was stable and resistant to photocorrosion during the photocatalytic degradation of TCL The higher efficiency of 7.2Fe/TiO2 compared to Degussa P25 under the optimal experimental conditions of TCL photodegradation, spontaneous precipitation of the suspension, possibility of reusing the catalyst, as well as an insignificant increase in the iron concentration in water solution, all this indicates the possibility of the practical application of this photocatalyst for water treatment.
