A wide range of semiconductor photocatalysts have been used over the years in water treatment to eliminate toxic organic substances from wastewater. The quest for visible or solar light driven photocatalysts with striking merits such as wide range of applications, ease of preparation, tailored architecture that gives rise to improved performance, ability of dual existence as both p type or n type semiconductor, among others, presents copper(i) oxide as a promising photocatalyst. This paper reviews the recent applications of CuO in photocatalytic and photoelectrocatalytic treatment of water laden with organic pollutants such as dyes and pharmaceuticals. It covers the various modes of synthesis, morphologies and composites or heterostructures of CuO as found in the literature. Concluding remarks and future perspectives on the application of CuO are presented.
多年来，各种各样的半导体光催化剂已被用于水处理，以去除废水中的有毒有机物质。对具有广泛应用范围、易于制备、能产生更高性能的定制结构、兼具p型或n型半导体等显著优点的可见光或太阳光驱动光催化剂的探索，使氧化亚铜成为一种有前景的光催化剂。本文综述了CuO在光催化和光电催化处理含染料和药物等有机污染物的水中的最新应用。它涵盖了文献中发现的CuO的各种合成模式、形态以及复合材料或异质结构。文中还给出了关于CuO应用的总结和未来展望。
