Photocatalytic activity of novel AgBr/WO3 composite photocatalyst under visible light irradiation for methyl orange degradation

Regulations of silver halide nanostructure and composites on photocatalysis

“…As photosensitive materials, AgX and Ag/AgX (especially X = Cl and Br) are regarded as suitable semiconductor selections to modify photocatalytic composition system, which can produce efficient coupling photocatalysts with higher activity and stability compared with the single component [270][271][272][273][274][275][276]. Among them, the hybridization between AgX and other metallic semiconductor would significantly improve the light absorption efficiency and facilitate the photoinduced charge carrier separation with similar transmission routes [277][278][279][280][281][282][283][284][285][286]. Such as in TiO 2 coupling system, the spectral absorption range tuning of TiO 2 is the key factor for its visible light photocatalytic performance modification [287][288][289][290][291][292].…”

Tungsten-based nanomaterials (WO 3 & Bi 2 WO 6 ): Modifications related to charge carrier transfer mechanisms and photocatalytic applications

“…A c c e p t e d M a n u s c r i p t 27 The other less commonly used semiconductors like BiOCl [142], Sb 2 O 3 [143], Ag 3 PO 4 [144], Fe 3 O 4 [145], NiWO 4 [146], SrNb 2 O 6 [147] and AgBr [148] are heterostructured with WO 3 to improve the photoactivity. The Fe 3 O 4 and NiWO 4 served as electron collectors to channelize the charge carriers, while others operated as sensitizers in the heterosystem (Fig.…”

Computational Fluid Dynamics (CFD) Modeling of Photochemical Reactors

“…TiO 2 powders could be employed in solar and UV irradiation systems (photoreactors) because this semiconductor has a high transparency to visible light, high refractive index, and low absorption coefficient. Wide range of metal oxides and sulfides have been used as photocatalysts including ZnO (Daneshvar et al, 2004;Sakthivel et al, 2003;Kormann et al, 1988;Khodj et al, 2001;Gouvêa et al, 2000;Lizama et al, 2002;Kansal et al, 2007;Chakrabarti and Dutta, 2004), WO 3 (Waldner et al, 2007;Sayama et al, 2010;Saepurahmanet et al, 2010;Cao et al, 2011), WS 2 (Jing and Guo, 2007), Fe 2 O 3 (Chen et al, 2001;Bandara et al, 2001;Pal and Sharon, 1998), V 2 O 5 (Akbarzadeh et al, 2010;Teramura et al, 2004a,b), CeO 2 (Lin and Yu, 1998;Coronado et al, 2002;Ji et al, 2009;Song et al, 2007), CdS (Bessekhouad et al, 2004;Reuterġardh and Langphasuk, 1997;Tang and Huang, 1995), ZnS (Torres-Martínez et al, 2001), and CuO (Lim and Kim, 2004;Sathishkumar et al, 2011;Nezamzadeh-Ejheieg and Hushmandrad, 2010). The light intensity in homogeneous and heterogeneous photoreactors determines the LVREA which is proportional to the rate of photochemical reaction.…”
