Synthesis of ZnWO4/Ag3PO4: p–n heterojunction photocatalyst with enhanced visible-light degradation performance of RhB

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

“…This property suggests that ZWO is suitably used as a photocatalyst for the photocatalytic decomposition of organic pollutants. , Nevertheless, the easy recombination of photocarriers limits the photoactivity of bare ZWO and its practical application in contaminant elimination. Multiple measures have been therefore used to improve the photocatalytic activity of ZWO (especially integrated with other semiconductors to form heterojunctions). − AMO is one of the important silver-based semiconductors, attracting considerable attention from researchers due to its promising photocatalytic capability, antimicrobial activity, and good photoluminescence property. , Furthermore, AMO also exhibits a synergistic flexo-photocatalytic degradation of organic pollutants under both simulated sunlight and ultrasonic irradiation . Although AMO has been shown to be promising in the photocatalytic removal of environmental pollutants, its photocatalytic activity still needs to be further improved via various avenues. − …”

Fabrication of polypyrrole-sensitized Ag3PO4/g-C3N4 Z-scheme heterojunction for photocatalytic and antibacterial activity

“…[13][14][15] Compared with the traditional heterojunction system, in the Zscheme system, the photoinduced electrons in the CB of the semiconductor (Ag 3 PO 4 ) could recombine with the holes in the VB of the semiconductor (g-C 3 N 4 ); thus, photogenerated electrons with strong reducibility and photogenerated holes with strong oxidation ability are separately accumulated on the surface of the opposite semiconductor and participate in the photocatalytic reaction. 16 Therefore, coupling appropriate semiconductors with Ag 3 PO 4 to construct a Z-scheme system can accelerate the electron transfer on the CB of Ag 3 PO 4 , which effectively prevents its photocorrosion and then improves the stability as well as the photocatalytic activity. Recently, H. Sun et al prepared bentonite-modified Ag 3 PO 4 /AgBr by an in situ precipitation method, showing an enhanced photocatalytic activity for the degradation of parabens compared with pure Ag 3 PO 4 and AgBr.…”
