Photocatalytic activity of AgI sensitized ZnO nanoparticles under visible light irradiation

Regulations of silver halide nanostructure and composites on photocatalysis

“…Heterogeneous system constituted by photoactive semiconductors is regarded as an effective method to facilitate the photoexcited electron-hole separation with enhanced photocatalytic activity [254][255][256][257][258][259][260][261][262][263][264][265][266][267][268][269]. Various metallic semiconductor (such as TiO 2 , ZnO, BiVO 4 ) and metal-free nitrogen-doped graphene semiconductors have been considered as preferred substances to composite with AgX, shown as Table 2.…”

Plasmon Mediated Photocatalysis by Solar Active Ag/ZnO Nanostructures: Degradation of Organic Pollutants in Aqueous Conditions

“…The enhancement in the photocatalytic performance and suppression of photocorrosion of ZnO via coupling with carbon materials and reduced graphene oxide showed good results in the photocatalysis [26]. Doping of ZnO [26] with metals [27], non metals [28], other compounds [29] and semiconductor materials [15] can also be considered to enhance visible range photocatalytic activity. Among them, doping with a noble metal (Ag and Au) is the most sought after idea due to LSPR (a unique property of conduction band electrons of noble metals to oscillate by incident light).…”

Effect of FeWO 4 doping on the photocatalytic activity of ZnO under visible light irradiation

“…The air was kept bubbling continuously into the aliquot by an air pump in order to provide a constant source of dissolved oxygen. Prior to light irradiation, the suspension was stirred in the dark for 30 min to ensure that the suspension is uniform [27,28]. A 300 W Xe arc lamp with an ultraviolet (l4,400 nm) cut off filter was used as the visible light irradiation source.…”
