Photocatalytic Degradation of Endocrine Disruptor Compounds in Water over Immobilized TiO2 Photocatalysts
Recently, the fate of endocrine disruptors in environmentally relevant samples has attracted considerable attention. Semiconductor photocatalysis may offer an appealing methodology to treat such contaminants. In this respect, the simultaneous degradation of synthetic hormones employing UV irradiation and TiO2 as the photocatalyst were investigated. Our interest was focused on des...
متن کاملPhotocatalytic Degradation of Amaranth Dye over Immobilized Nano-crystals of TiO2
-The present work is focused on the heterogeneous photocatalytic degradation of Amaranth dye over immobilized nano-crystals of TiO2. Immobilization has been an acceptable approach to overcome the drawbacks encountered with powder suspensions. Immobilization is performed using polyvinyl alcohol-formaldehyde binder. This method of immobilization does not require thermal heating at high temperatur...
متن کاملUV/TiO2 photocatalytic degradation of xanthene dyes.
UV/titanium dioxide (TiO(2)) degradation of two xanthene dyes, erythrosine B (Ery) and eosin Y (Eos), was studied in a photocatalytic reactor. Photocatalysis was able to degrade 98% of Ery and 73% of Eos and led to 65% of chemical oxygen demand removal. Experiments in buffered solutions at different initial pH values reveal the pH dependence of the process, with better results obtained under ac...
متن کاملNitrogen doped TiO2 for efficient visible light photocatalytic dye degradation
In this study, Nitrogen doped TiO2 photocatalysts were prepared by the sol gel method and physicochemical properties were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM), photoluminescence, and energy dispersive X-ray spectroscopy (DRS) techniques. The XRD data indicated that the nanoparticles had the same crystals structures as the pure TiO2</su...
متن کاملPhotocatalytic Oxidation Processes for Toluene Oxidation over TiO2 Catalysts
Gas-solid heterogeneous photooxidation of toluene over TiO2 catalyst was studied to investigate the factors controlling the catalytic activities. The toluene photooxidation behavior on TiO2 was strongly affected by the formation and oxidation behavior of intermediate compounds on TiO2, and their accumulation decreased the reaction rate for toluene photooxidation. The formation and oxidation beh...
