Enhancement of oxygen vacancies and solar photocatalytic activity of zinc oxide by incorporation of nonmetal

Effect of oxygen vacancy on enhanced photocatalytic activity of reduced ZnO nanorod arrays

“…This can be ascribed to Oxygen vacancy defects induce new donor energy levels below its conduction band [26]. Recently, researchers have taken their attentions to the creation of oxygen vacancy to improve photocatalytic activity of ZnO nanomaterials using different techniques [27][28][29][30][31].…”

New insight into the enhanced photocatalytic activity of N-, C- and S-doped ZnO photocatalysts

“…Among these methods, band gap engineering through metal or nonmetal doping is considered as one of the most effective strategies and has been widely adopted [37][38][39][40].…”

Direct in situ activation of Ag0 nanoparticles in synthesis of Ag/TiO2 and its photoactivity

“…In addition, increasing Ag loading seemed to shift the TiO 2 diffraction peak at (1 0 1) toward a slightly lower angle, from 25.44 • to 25.30 • (figure not shown). This phenomenon is most probably due to the introduction of Ag causing shrinkage of some of the TiO 2 crystallite planes, resulting in disordering of the crystallinity of the TiO 2 [33,34]. In addition, the value of d 1 0 1 was found to increase with increasing Ag loading, also suggesting an interaction between Ag and TiO 2 ( Table 1).…”
