Progress in visible photocatalytic degradation of organic pollutants by Ag2CO3 heterojunction
Silver carbonate(Ag2CO3)has an important position in photocatalysis because of its optical properties such as broadband photoresponse,strong redox ability and high mobility.However,the poor stability and severe carrier complexation have limited the practical application of Ag2CO3 photocatalysts.The construction of semiconductor heterojunction photocatalytic system is one of the effective approaches to realize photocatalytic treatment of organic pollutants.This text introduces the reaction process of Ag2CO3 as a photocatalyst,to investigate the catalytic performance of Ag2CO3 photocatalytic degradation of organic contaminants from the perspective of constructing heterojunctions(type-Ⅱ,PN,Z-scheme,S-scheme and graphene-based heterojunctions).Finally,an outlook on the research focus of Ag2CO3 photocatalysts is presented.
