含铜半导体氧化物的光催化应用进展

应用半导体材料光催化降解污染物和光催化分解水制氢是近几十年来的材料研究热点之一。从拓展光催化材料种类的角度出发,本文对含铜半导体氧化物的基本性质、制备方法及其在光催化方面的应用情况进行了综述。所涉及的氧化物包括含一价铜的氧化亚铜和铜铁矿类复合氧化物,以及含二价铜的氧化铜和尖晶石类复合氧化物。指出将含铜p型半导体氧化物与n型半导体材料复合,制备p-n异质型复合氧化物是有前途的研发方向。

Photocatalytic research progress of Cu-based semiconductor oxides

It is a hot point in material research area,that semiconductive materials are used to split water for hydrogen evolution and degrade pollutants,in recent decades.From the point of the development range of photocatalyst material,the basic properties,preparation method and the photocatalytic application of the containing copper semiconductor oxides are summarized.The oxides discussed in this paper include two kinds of oxides,the first type containing Cu(Ⅰ) named cuprous oxide and delafossite oxides,and second type containing Cu(Ⅱ) named copper oxide and spinelle composite oxides.Composing Cu-based semiconductor oxides with n-type semiconductor material to obtain p-n heterogeneity composite oxides should be a promising research direction.
