Review on the advancement of SnS2 in photocatalysis

Abstract

SnS₂ is a CdI₂-type layered non-noble metal sulfide semiconductor. SnS₂ has the characteristics of suitable band gap, good photochemical stability, excellent photoelectrical activity and high carrier mobility, which enable its photoelectric and photocatalytic application prospects. In this study, the progress of SnS₂ application in photocatalysis is reviewed. The properties of SnS₂ materials in various photocatalytic applications and related mechanisms are introduced. The main activity improvement methods of SnS₂ photocatalysts and possible development directions in the future are discussed and researched.
