摘　　要：ZnO具有光催化活性强、热稳定性高、无毒无污染等优点,是研究最广泛的光催化材料之一。ZnO禁带宽度大,只能吸收紫外光,太阳能利用率低;且其光生电子易与空穴复合,量子效率低。CuO作为一种窄带隙半导体,与ZnO复合形成半导体异质结,不仅可以提高太阳光利用率,而且能加快载流子转移,提高光催化性能。介绍了CuO/ZnO复合光催化材料的制备方法,综述了国内外CuO/ZnO复合光催化材料的研究进展,并展望了其未来研究方向。ZnO has been widely studied as a photocatalytic material due to its high photocatalytic activity,high thermal stability,non-toxic and pollution-free.ZnO has a wide band gap,which can only absorb ultraviolet light and has low solar energy utilization rate.Moreover,the photogenerated electrons are easy to recombine with holes,and the quantum efficiency is low.As a narrow band gap semiconductor,CuO can improve the utilization rate of sunlight,accelerate the carrier transfer and improve the photocatalytic performance when it is combined with ZnO to form a semiconductor heterojunction.The research progress on CuO/ZnO composites in photocatalysis was reviewed according to different preparation methods.
