Facile fabrication of AgI/Sb2O3 heterojunction photocatalyst with enhanced visible-light driven photocatalytic performance for efficient degradation of organic pollutants in water

Enhanced photocatalytic performance of ZnO/AgCl composites prepared by high-energy mechanical ball milling

“…Heterojunction structures were usually reported in composite materials that were prepared by a deposition-precipitation method. 64,65 With this in mind, we prepared ZnO/AgCl composite using the deposition-precipitation method (DP-ZA-60%) and compared its photocatalytic activity with that of BM-ZA-60% composite and simple mixed ZnO/AgCl sample (SM-ZA-60%). The photodegradation of RhB and photooxidation of 1,4-DHP with DP-ZA-60% were much faster than those in the presence of SM-ZA-60% (Fig.…”

Construction of Z-Scheme Ag2MoO4/ZnWO4 Heterojunctions for Photocatalytically Removing Pollutants

“…The construction of semiconductor–semiconductor heterojunctions has been demonstrated to be a good strategy for promoting the spatial separation of light-induced holes and electrons. − In our previous publication, we have systematically analyzed and compared eight types of heterojunctions. There are two key factors governing the transfer behavior of photocarriers in heterojunctions, i.e., work functions and valence/conduction band (VB/CB) potentials of the constituent semiconductors.…”

Facile fabrication of a SnS2/Ag3VO4 Z-scheme heterojunction for boosting visible-light photocatalytic activity

“…As a type of VL-responsive semiconductors, a range of silver-based semiconductors have aroused extensive interest among scientists thanks to their huge potential in the photocatalysis field. [6][7][8][9][10][11] Among them, silver vanadate (Ag 3 VO 4 ) is an appealing VL photocatalyst for organic pollutant removal on account of its narrow band gap (∼2.2 eV) and good crystallization. 12,13 In addition, it can also act as a sensitizer to improve the VL absorption of a large band gap semiconductor.…”
