摘　　要：Cu_(2)O是一种p型半导体,在光催化领域有着广阔的应用前景。研究者通过调控Cu_(2)O形貌和尺寸、构建异质结结构、设计复合材料增大比表面积和导电性等手段,提高其光利用率,降低了光生电子-空穴对复合率,从而提高了Cu_(2)O的光催化活性和光稳定性,促进了其在光催化降解染料领域的应用。本文重点综述了通过元素掺杂、半导体异质结构建及与其他材料复合的途径增强Cu_(2)O光催化性能的方法,归纳了其在光催化降解有机污染物方面的应用及异质结增强机理,指出了目前研究存在的短板,并对氧化亚铜基复合光催化的发展及应用前景进行了展望。Cu_(2)O is a kind of p-type semiconductor,which has a wide application prospect in the field of photocatalysis.By adjusting the morphology and size of Cu_(2)O,constructing the heterojunction structure,designing the composite material to increase the specific surface area and electrical conductivity,the light utilization rate of Cu_(2)O was improved and the photogenerated electron-hole pair recombination rate was reduced,thus improving the photocatalytic activity and photostability of Cu_(2)O,and promoting its application in the field of photocatalytic degradation of pollutant.In this paper,the methods to enhance the photocatalytic performance of Cu_(2)O,including metal doping,semiconductor heterostructure construction and composites synthesis,were reviewed.Its application in photocatalytic degradation of organic pollutants and the enhancement mechanism of heterojunction were summarized.In addition,the shortcomings of current research were pointed out.The development and application prospect of cuprous oxide based photocatalysis were also prospected.
