Photocatalytic performance of nanometer-sized FexOy/TiO2 particle synthesized by hydrothermal method

Photocatalytic performance of nano-photocatalyst from TiO2 and Fe2O3 by mechanochemical synthesis

“…These are crucial to the photocatalytic reactions since they can react with photoexcited holes generated on the catalyst surface and produce hydroxyl radicals [41], which act as powerful oxidant. The absorption band around 1200 cm −1 may be assigned to the Ti-O-Ti bending [37]. …”

“…Y 2 O 3 /Fe 2 O 3 /TiO 2 nanoparticles [35], which showed better photooxidation for EDTA than pure TiO 2. Recently, Fe 2 O 3 /TiO 2 heterogeneous mixed oxides [36][37][38][39] have shown better photocatalytic activity than pure TiO 2 for oxidation of different organic compounds such as methylene blue, chloroform and formaldehyde but it is inferior to Degussa P 25. In this study a homogeneous solution between Fe 2 O 3 and TiO 2 has been made by high energy mechanical milling using various source of Fe 3+ which shows high 0925 photochemical activity and it is more active than Degussa P 25 in visible light for oxidative degradation of various dyes.…”

Enhancement of photocatalytic activity of P25 TiO2 by vanadium-ion implantation under visible light irradiation

“…Generally, when semiconductor materials receive energy from the outside, the electron from the valence band transfers to the conduction band and strongly oxidizes some volatile organic compounds [34]. Since excitation was carried out under equal adsorption conditions at 285 nm, the decrease in emission intensities must originate from the differences in electronic structure of the metal-doped samples.…”

Preparation of photocatalytic Fe2O3–TiO2 coatings in one step by metal organic chemical vapor deposition

“…For instance, Kang et al prepared the nanometer particles of Fe 2 O 3 /TiO 2 through the hydrothermal and impregnation method, and found that Fe components were well inserted into the framework of the TiO 2 anatase structure [6]. Pal et al developed binary mixed oxide of Fe/Ti with homogeneous distribution of iron into the TiO 2 by sol-gel.…”
