ZnWO 4 nanorods decorated with Ag/AgBr nanoparticles as highly efficient visible-light-responsive photocatalyst for dye AR18 photodegradation

Room-temperature synthesis and solar photocatalytic performance of MoO3·0.5H2O nanorods

“…Since the above organic dyes show high structural stability under the natural light, the degradation of them via the photolysis mechanism is negligible. For the photosensitization process of dye, photo-induced electrons in the dye transfer to the conduction band of the catalyst that absorbs the dye, and subsequently react with molecular oxygen to produce the · O 2 -radical [4,34]. For the photocatalytic process, photo-induced electrons and holes existing over a semiconductor react with O 2 and OH -to form active oxidants · O 2 -and · OH -, respectively [35][36][37].…”

Ternary ZnO/AgBr/Ag2CrO4 nanocomposites with tandem n–n heterojunctions as novel visible-light-driven photocatalysts with excellent activity

“…Due to their narrow band gaps, silver containing semiconductors such as AgBr, AgI, Ag 3 PO 4 , AgVO 3 , Ag 3 VO 4 , and Ag 2 CO 3 have considerable absorption in the visible range, leading to generation of more electron-hole pairs and enhanced photocatalytic activity in this region. Hence, in recent years, they have been extensively applied in preparation of various visible-light-driven photocatalysts [8][9][10][11][12][13][14][15]. However, these semiconductors have three main drawbacks that restrict their practical applications in a large scale.…”

Non-thermal plasma-assisted growth of ZnWO4 hierarchical nanostructures: morphology, structure and photoactivity

“…Recently, for improved photoinduced charge carriers separation and reducing the recombination of electronhole pairs, ZnWO4 was coupled with other semiconducting materials such as, ZnO, Bi2WO6, Ag/AgBr, Ag/AgCl, BiOI, In2S3, Ag3PO4, Fe2O3, CdWO4 etc. to fabricate various heterostructures [10][11][12][19][20][21][22][23][24][25]. For instance, Wang et al have reported In2S3/ZnWO4 composites, which are exhibited enhanced photo-catalytic activity than that of the individual In2S3 and ZnWO4 [22].…”
