A Bi₂WO₆/Ag₂S/ZnS Z-scheme heterojunction photocatalyst with enhanced visible-light photoactivity towards the degradation of multiple dye pollutants

Abstract

A Z-scheme Bi2WO6/Ag2S/ZnS heterojunction was successfully synthesized as a novel visible-light-driven photocatalyst for the degradation of multiple dye pollutants.

Photocatalytic degradation of organic dye and tetracycline by ternary Ag2O/AgBr–CeO2 photocatalyst under visible-light irradiation

“…In the whole ternary catalytic reaction process, photo-generated carriers can be transferred in multiple steps through the induction mechanism to achieve the purpose of electron and hole separation, thereby achieving photocatalytic activity beyond the binary catalytic system 17 , 18 . And an increasing number of ternary photocatalytic materials have been reported, such as Fe 3 O 4 /Bi 2 S 3 /BiOBr 19 , Ag 3 PO 4 /TiO 2 /Fe 3 O 4 20 , Bi 2 WO 6 /Ag 2 S/ZnS 21 , and V 2 O 5 /BiVO 4 /TiO 2 22 . In spite of some ternary composites reported, there are few reports about cerium dioxide ternary materials.…”

The effective photocatalysis and antibacterial properties of AgBr/AgVO3 composites under visible-light

“…Furthermore, compared to other reported antibacterial photocatalysts, such as BiOI/BiVO 4 , 1 Cu 2 O 28 and ZnO–Bi 2 O 3 , 29 the 0.5 AgBr/AgVO 3 composites showed better photocatalytic antibacterial activity, making it a potential photocatalyst in antibacterial area.…”

Tribocatalytic degradation of dyes by tungsten bronze ferroelectric Ba2.5Sr2.5Nb8Ta2O30 submicron particles

“…The colorful world created by the application of dyes in the elds of textiles and printing plays an important role in enriching people's material and cultural lives. 1,2 However, a large amount of dye wastewater is generated, which has the characteristics of large volume, complex components, deep chroma, and difficult degradation. Moreover, most dyes are toxic and carcinogenic, seriously polluting the natural environment.…”
