“…This could be emphasized that the S cations in the sample are present in S 6+ state which is similar to the previous studies. 36,37 The Ti 2p 3/2 and Ti 2p 1/2 binding energies (Fig. 3d) were observed at 459.3 and 464.7 eV respectively.…”

“…In terms of the kinetic study, the apparent pseudo-first order rate constant (k) was obtained to estimate in which condition the highest degradation of the dye occurred, according to a Langmuir-Hinshelwood model. 24 The k values were calculated from the linear relationship between ln (C 0 / C) and irradiation time.…”

The present study evaluated the main factors that influence the photocatalytic activity of titanium dioxide (TiO 2 ) films grown by metalorganic chemical vapor deposition (MOCVD) at 400 and 500 °C, in different growth times. The photocatalytic behavior was analyzed by measuring the methyl orange dye degradation at different pH values. Structural and morphological characteristics, and the recyclability of the catalysts for several cycles were also investigated. Anatase phase was identified in all films. The higher photodegradation performances were obtained at acidic pH. The results demonstrated that the photocatalyst thickness is an important parameter in heterogenous photocatalysis. The best photocatalytic result occurred for the 395 nm-thick TiO 2 film grown at 400 °C, which presented 65.3% of the dye degradation under UV light. The recyclability experiments demonstrated that the TiO 2 films grown by MOCVD present a great stability after several photocatalytic cycles, which allows their practical application for water treatment with high efficiency.

MgFe2O4-B/Ag3VO4 visible light active photocatalyst was successfully synthesized for the photocatalytic decolorization of organic pollutants. Malachite green (MG) was selected as a model dye representing those pollutant chemicals. The catalyst was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS). Malachite green (MG) decolorization was carried out by visible light irradiation of a 105 W tungsten light source. Decolorization yield and kinetic studies were traced by the help of a UV-Vis spectrophotometer. Kinetic model of decolorization was derived from Langmuir-Hinshelwood (L-H) model and found coherent to first order kinetics. Catalysis reaction showed high dependency on pH especially out of 5-7 range which gave high decolorization. Photocatalytic activity also depended on concentration with dual character in which high concentration hindered the light coming to catalyst surface but on the other hand it supported the activity by boosting the dark adsorption resulting in a decolorization time changing fro m 40 to 100 min. After the reaction was completed, powders of catalyst were effortlessly removed from the medium by a magnet bar. It was shown that MgFe2O4-B/Ag3VO4 photocatalyst has a potential to be simple and efficient alternative material for the removal pollution resources from wastewaters.
