Photooxidation of eosin Y in the presence of semiconducting oxides

Adsorption and photodegradation of Procion yellow H-EXL dye in textile wastewater over TiO2 suspension

“…Among these treatments, advanced oxidation processes (AOPs) are powerful alternative to conventional treatment methods for such wastewater decontamination (Andreozzi et al 1999;Munter et al 2001;Tarr et al 2003;Parsons et al 2004). Most of those works were focused on treatment with Fenton, photo-Fenton (UV/Fenton) or photoFenton-like reactions (Kang et al 2000;Feng et al 2003;Neyens et al 2003;Swaminathan et al 2003;Lucas et al 2006;Sanja et al 2008), UV + H 2 O 2 (or O 3 ) (Arslan et al 1999;Karadimas et al 2003;Arslan et al 2002), photocatalysis (UV + TiO 2 or other semiconductor particles) (Arslan et al 2000;Tanaka et al 2000;Poulios et al 2003;Rao et al 2003;Danfeng et al 2004;Dong et al 2007;Wu et al 2008). These treatments are based on the in situ generation of highly reactive hydroxyl radicals (HO•).…”

Photocatalytic degradation of Remazol Red F3B using ZnO catalyst

“…TiO 2 [19][20][21][22][23], and ZnO [24][25][26][27][28][29][30] especially in recent years, are used as effective, inexpensive and nontoxic semiconductor photocatalysts for the degradation of a wide range of organic chemicals and synthetic dyes. Moreover, visible light-induced degradation of an azo dye on coupled TiO 2 /CdO-ZnO nanoporous films was also investigated to show higher photocatalytic activity [31].…”

Photocatalytic degradation and antibacterial investigation of nano synthesized Ag3VO4particles @PAN nanofibers

“…To address this challenge, in the past decade, various semiconductor photocatalysts such as BiPO4, BiPO 4 /CeO 2 , TiO 2 /CdS, etc. have been successfully prepared and reported in relation to the decomposition of organic compounds or antibacterial activities utilizing visible light [13][14][15]. Photocatalysts based on semiconductor materials involve the generation of electron and hole pairs, migrating to the surface of the semiconductor, which contributes to the conversion of organic pollutants and inorganic pollutants into harmless substances and destruction of bacteria by a series of redox processes [16,17].…”
