Emerging polynary bismuth-based photocatalysts:Structural classification,preparation,modification and applications
Photocatalysis is widely recognized as a promising technique for addressing energy and environ-mental challenges.Exploring novel photocatalysts represents a crucial avenue for advancing the development of photocatalytic technology.Bismuth(Bi)-based photocatalysts have garnered signif-icant attention due to their distinctive crystal structure,favorable hybrid electronic band structure and diverse composition.In recent years,numerous polynary Bi-based(PBB)photocatalysts have been investigated,which exhibit excellent photocatalytic performance.However,most reviews still primarily focus on summarizing traditional materials,it is necessary and urgent to provide a com-prehensive review of emerging PBB photocatalysts reported in recent years.This review encom-passes the latest advancements in emerging PBB photocatalysts over the past decade(approxi-mately 60 species),covering crystal structure,synthesis method,modification approaches and ap-plication areas.This review provides a concise summary and offers insight into future research trends of emerging PBB photocatalysts and guidance for finding suitable applications based on their crystal structures.
