AB  - Nowadays, great focus is given to the contamination of surface and groundwater because of the extensive usage of pesticides in agriculture. The improvements of commercial catalyst TiO2 activity using different Au nanoparticles were investigated for mesotrione photocatalytic degradation under simulated sunlight. The selected system was 2.43 × 10−3% Au–S–CH2–CH2–OH/TiO2 (0.5 g/L) that was studied by transmission electron microscopy and ultraviolet-visible (UV-Vis) spectroscopy. It was found that TiO2 particles size was ~20 nm and ~50 nm, respectively. The Au nanoparticles were below 10 nm and were well distributed within the framework of TiO2 . For 2.43 × 10−3% Au–S–CH2–CH2–OH/TiO2 (0.5 g/L), band gap energy was 2.45 eV. In comparison to the pure TiO2, addition of Au nanoparticles generally enhanced photocatalytic removal of mesotrione. By examining the degree of mineralization, it was found that 2.43 × 10−3% Au–S–CH2–CH2–OH/TiO2 (0.5 g/L) system was the most efficient for the removal of the mesotrione and intermediates. The effect of tert-butanol, NaF and ethylenediaminetetraacetic acid disodium salt on the transformation rate suggested that the relative contribution of various reactive species changed in following order: h+ >•OHads >•OHbulk. Finally, several intermediates that were formed during the photocatalytic treatment of mesotrione were identified. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

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. © 2018 The Korean Society of Industrial and Engineering Chemistry

AB  - A comprehensive study of the removal of selected biologically active compounds (pharmaceuticals and pesticides) from different water types was conducted using bare TiO2nanoparticles and TiO2/polyaniline (TP-50, TP-100, and TP-150) nanocomposite powders. In order to investigate how molecular structure of the substrate influences the rate of its removal, we compared degradation efficiency of the initial substrates and degree of mineralization for the active components of pharmaceuticals (propranolol, and amitriptyline) and pesticides (sulcotrione, and clomazone) in double distilled (DDW) and environmental waters. The results indicate that the efficiency of photocatalytic degradation of propranolol and amitriptyline was higher in environmental waters: rivers (Danube, Tisa, and Begej) and lakes (Moharač, and Sot) in comparison with DDW. On the contrary, degradation efficacy of sulcotrione and clomazone was lower in environmental waters. Further, of the all catalysts applied, bare TiO2and TP-100 were found to be most effective in the mineralization of propranolol and amitriptyline, respectively, while TP-150 appeared to be the most efficient in terms of sulcotrione and clomazone mineralization. Also, there was no significant toxicity observed after the irradiation of pharmaceuticals or pesticides solutions using appropriate catalysts on rat hepatoma (H-4-II-E), mouse neuroblastoma (Neuro-2a), human colon adenocarcinoma (HT-29), and human fetal lung (MRC-5) cell lines. Subsequently, detection and identification of the formed intermediates in the case of sulcotrione photocatalytic degradation using bare TiO2and TP-150 showed slightly different pathways of degradation. Furthermore, tentative pathways of sulcotrione photocatalytic degradation were proposed and discussed.

AB  - Titanium dioxide nanotubes (TNT) were synthesized via hydrothermal method and calcined at various temperatures. The obtained calcined TiO2 nanomaterials with specific elongation orientation were characterized by transmission and scanning electron microscopy (TEM, SEM), X-ray diffraction (XRD), UV/Vis diffuse reflection spectroscopy (DRS), Laser Doppler electrophoresis (LDE) and their textural properties were evaluated. The photocatalytic activity of obtained nanopowders was evaluated considering photodegradation rate of herbicide clomazone, rarely studied herbicide. The influence of calcination temperature of catalysts with elongated morphology on their photocatalytic activity was evaluated. The best results were obtained with TNT annealed at 700 degrees C, which can be assigned to the best balance between crystal structure, morphology and surface properties of nanoparticles induced by annealing. Also, the photocatalytic degradation rates of another two herbicides (picloram, and mecoprop) were compared, due to possibility that the efficiency of photo catalytic degradation is greatly influenced by the molecular structure. The mineralization degree of selected herbicides in the presence of TiO2 based photocatalysts was evaluated applying total organic carbon (TOC) measurements. (C) 2014 Elsevier B.V.

AB  - A study of photocatalytic activity of bare as prepared, bare aged and dopamine surface modified colloidal TiO2 nanoparticles was obtained following degradation reaction of herbicide RS-2-(4-chloro-o-tolyloxy)propionic acid under UV light irradiation. Results showed that the most active photocatalyst is bare aged TiO2 and the least active are dopamine modified nanoparticles. Results are discussed in the light of surface structure of TiO2 nanoparticles. The study of surface modification of TiO2 nanoparticles (4.5 nm, TiO2 NPs) with dopamine was also performed. The formation of inner-sphere charge-transfer complexes results in red shift of semiconductor absorption threshold (600 nm), compared to bare TiO2 NPs (380 nm). Effective band gap energy of 3.2 eV for bare TiO2 NPs is reduced to 2.1 eV for TiO2/dopamine charge transfer complexes. The binding structure was investigated by UV-vis and FTIR spectroscopy. The obtained optimal geometry for binding of dopamine to surface Ti atoms was binuclear bidentate-bridging. From the Benesi-Hildebrand plot, stability constant of the order 10(3) M-1 has been determined. (C) 2013 Elsevier B.V. All rights reserved.

AB  - Titanium dioxide is one of the most studied semiconductors because of its wide range of potential technological applications including pigments, cosmetics, photovoltaic cells and catalysis. TiO2 has three most commonly encountered crystalline polymorphs: anatase, brookite and rutile. The possible application of TiO2 critically depends on crystalline structure, size and shape of the particles. Rutile has the highest density and refractive index and is widely employed in pigments and cosmetic industry. TiO2 is transparent in the visible light region; its band gap is 3.0 eV for rutile and 3.2 eV for anatase crystalline phase. By doping or sensitization, it is possible to improve the optical activity of TiO2 and to move its absorption threshold into the visible light region. The subject of this chapter is different rutile nanostructures of pure and Fe3+- doped titania which were synthesized by co-precipitation in acidic aqueous solution. Obtained materials were characterized by structural (XRD), morphological (TEM and HRTEM), optical (UV/vis absorption, reflection, and photoluminescence), and analytical (XPS and ICP-OES) techniques. Also, photo-catalytic activity measurements were performed, using photo-degradation of specific herbicides as model systems. Applied synthetic procedure resulted in formation of flower like agglomerates of 200-400 nm in diameter. Agglomerates represent assembly of nano-rods consisted of “chains” of spherical particles, 5-7 nm in diameter, most likely interconnected through the so-called oriented attachment or grain-rotation induced-grain coalescence (GRIGC) process. The presence of dopant iron ions didn’t distract morphology of rutile nano-particles, nor agglomerates, but significantly changed optical properties of titania compared to pure material. The photoluminescence of pure and Fe-doped rutile nano-particles is characterized with several well-resolved peaks extending in the visible spectral region. Photon energy upconversion from rutile TiO2 nano-particles was also observed at low excitation intensities. The energy of up-converted photoluminescence spans the range of emission of normal photoluminescence. The explanation of photon energy up-conversion involves mid-gap energy levels originating from oxygen vacancies. © 2012 by Nova Science Publishers, Inc.

abstract = "Titanium dioxide is one of the most studied semiconductors because of its wide range of potential technological applications including pigments, cosmetics, photovoltaic cells and catalysis. TiO2 has three most commonly encountered crystalline polymorphs: anatase, brookite and rutile. The possible application of TiO2 critically depends on crystalline structure, size and shape of the particles. Rutile has the highest density and refractive index and is widely employed in pigments and cosmetic industry. TiO2 is transparent in the visible light region; its band gap is 3.0 eV for rutile and 3.2 eV for anatase crystalline phase. By doping or sensitization, it is possible to improve the optical activity of TiO2 and to move its absorption threshold into the visible light region. The subject of this chapter is different rutile nanostructures of pure and Fe3+- doped titania which were synthesized by co-precipitation in acidic aqueous solution. Obtained materials were characterized by structural (XRD), morphological (TEM and HRTEM), optical (UV/vis absorption, reflection, and photoluminescence), and analytical (XPS and ICP-OES) techniques. Also, photo-catalytic activity measurements were performed, using photo-degradation of specific herbicides as model systems. Applied synthetic procedure resulted in formation of flower like agglomerates of 200-400 nm in diameter. Agglomerates represent assembly of nano-rods consisted of “chains” of spherical particles, 5-7 nm in diameter, most likely interconnected through the so-called oriented attachment or grain-rotation induced-grain coalescence (GRIGC) process. The presence of dopant iron ions didn’t distract morphology of rutile nano-particles, nor agglomerates, but significantly changed optical properties of titania compared to pure material. The photoluminescence of pure and Fe-doped rutile nano-particles is characterized with several well-resolved peaks extending in the visible spectral region. Photon energy upconversion from rutile TiO2 nano-particles was also observed at low excitation intensities. The energy of up-converted photoluminescence spans the range of emission of normal photoluminescence. The explanation of photon energy up-conversion involves mid-gap energy levels originating from oxygen vacancies. © 2012 by Nova Science Publishers, Inc.",

AB  - The aim of this work was to study the efficiency of Fe- and N-doped titania suspensions in the photocatalytic degradation of the herbicides RS-2-(4-chloro-o-tolyloxy)propionic acid (mecoprop, MCPP), (4-chloro-2-methylphenoxy)acetic acid (MCPA), and 3,6-dichloropyridine-2-carboxylic acid (clopyralid, CP) under the visible light (lambda GT = 400 nm) irradiation. The obtained results were compared with those of the corresponding undoped TiO(2) (rutile/anatase) and of the most frequently used TiO(2) Degussa P25. Computational modeling procedures were used to optimize geometry and molecular electrostatic potentials of MCPP, MCPA and CP and discuss the obtained results. The results indicate that the efficiency of photocatalytic degradation is greatly influenced by the molecular structure of the compound. Lowering of the band gap of titanium dioxide by doping is not always favorable for increasing photocatalytic efficiency of degradation. (C) 2010 Elsevier B.V. All rights reserved.

AB  - The work describes a study of the oxidation power of nitrogen-doped titanium dioxide (TiO2) suspensions for photocatalytic degradation of the herbicides RS-2-(4-chloro-o-tolyloxy) prop ionic acid (mecoprop) and (4-chloro-2methylphenoxy)acetic acid (MCPA) using various light sources. The nitrogen-doped TiO2 crystalline nanopowder was synthesized by calcination of the hydrolysis product of titanium tetraisopropoxide in ammonia. The product was an anatase crystal phase with mean particle diameter 7-15 nm and specific surface area of 121 +/- 1 m(2) g(-1). It showed visible-light photocatalytic activity at about 530 rim. Although nitrogen concentration in nitrogen-doped TiO2 is low ( LT 1 atomic %), it appeared to be about 1.5 times more efficient than TiO2 Degussa P25 when artificial visible light was used for mecoprop and MCPA degradation, and about six times compared to direct photolysis. It was found that the optimal content of nitrogen-doped TiO2 was 4 mg cm(-3). The photodegradation of the herbicide aromatic ring takes place simultaneously with chloride evolution, whereby the reaction in both cases follows first-order kinetics.

AB  - The kinetics and possible mechanism of the photocatalytic degradation of herbicide mecoprop, in UV illuminated aqueous colloids of synthesized nanosized TiO2 were investigated. The rate of degradation was studied by H-1 NMR, UV spectrometry, as well as by potentiometric titrimetric determination of generated chloride. The catalyst dosage and effects of other kinetic factors on the photocatalytic degradation, such as initial substrate concentration, temperature and type of TiO2 were investigated as well. The degradation rates were found to be strongly influenced by the above parameters. It was found that photocatalytic efficiency is lower and that a smaller number of observed organic intermediates (only 4-chloro-2-methylphenol and acetic acid) was detected than those observed in the presence of TiO2 (Degussa P-25). Kinetics of the degradation were also monitored for direct photolysis, as well as for solar degradation in the presence and in the absence of TiO2. (C) 2004 Elsevier B.V. All rights reserved.
