Abstract: 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.
