摘　　要：环境与能源问题严峻,人们迫切需要开发一些高效、环保、稳定的光催化剂。卤氧化铋(BiOX,X为Cl、Br、I)因其独特的层状结构、优异的光学、电学性能而受到光催化领域的广泛关注。但BiOX存在光吸收不足、电子−空穴(electron-hole,e^(−)−h^(+))快速复合、载流子浓度有限等问题而限制了它的应用。利用碳材料修饰BiOX可以极大地提升BiO X的光催化性能。简要介绍了BiOX的结构、性质、改性方案,碳材料基本类型和性质,主要综述了近几年零维,一维,二维,三维碳材料改性的BiOX光催化剂的研究进展,并分析了碳材料对BiOX光催化剂的提升机制,最后展望了碳材料改性的BiOX所面临的机遇和挑战。Due to the severe environmental and energy problems,there is an urgent need to develop some efficient,environmentally friendly and stable photocatalysts.Bismuth oxyhalide(BiOX,X=Cl,Br,I)has attracted extensive attention in the field of photocatalysis because of its unique layered structure,excellent optical and electrical properties.However,due to the insufficient visible light absorption,rapid electron-hole(e^(−)-h^(+))recombination and limited carrier concentration,the application of BiOX is limited.Carbon material modification can greatly improve the photocatalytic performance of BiOX.This paper briefly introduces the structure,properties,modification scheme of BiOX and the basic types and properties of carbon materials.The research progress of zero-dimensional,one-dimensional,twodimensional and three-dimensional carbon materials modified BiOX photocatalyst in recent years has been mainly reviewed,and the improvement mechanism of carbon materials on BiOX photocatalyst is analyzed.Finally,the opportunities and challenges faced by carbon materials modified BiOX are prospected.
