摘　　要：Ag_(2)CO_(3)具有宽带光响应、强氧化还原能力和高迁移率等光学性质,在光催化领域中具有重要地位。然而较差的稳定性及严重的载流子复合等问题,限制了Ag_(2)CO_(3)光催化剂的实际应用。构建半导体异质结光催化体系是实现光催化降解有机污染物的有效途径之一。介绍了Ag_(2)CO_(3)作为光催化剂的反应机理,从构建异质结(Ⅱ型、PN型、Z型、S型和石墨烯基异质结)的角度探讨Ag_(2)CO_(3)光催化降解有机污染物的催化性能,对Ag_(2)CO_(3)光催化剂的研究重点进行了展望。Silver carbonate(Ag_(2)CO_(3))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 Ag_(2)CO_(3) 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 Ag_(2)CO_(3) as a photocatalyst,to investigate the catalytic performance of Ag_(2)CO_(3) 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 Ag_(2)CO_(3) photocatalysts is presented.
