Abstract

Abstract:

Due to its excellent visible light photocatalytic performance, Ag₃PO₄ has wide application prospective in many fields, such as organic pollutant degradation, water decomposition and CO₂ reduction. However, there is still a great gap between photocatalytic performance of Ag₃PO₄ and requirement for practical applications, besides its unstable chemical properties. A plenty of work has been contributed to performance improvement of Ag₃PO₄. This review was focused on photocatalytic performance improvement and enhancement mechanism of Ag₃PO₄ by means of nanonization, morphology control, and structure heterogenization. So far, the most popular approach had been development of Ag₃PO₄ heterostructure, which heterostructures with metal oxides, sulfides, halides, organic semiconductors, and metals effectively improved photocatalytic performance. Future development trend of Ag₃PO₄ photocatalysts were also prospected.

摘要：

Ag₃PO₄是目前光催化效率最高的可见光光催化剂之一，在降解有机污染物、分解水制氢和CO₂还原等领域具有广泛的应用前景。但Ag₃PO₄光催化性能距离实际应用还存在一定差距，化学性质也不稳定，因此对其性能提升受到了各国研究者的关注。围绕Ag₃PO₄纳米化、形貌控制、异质结构等提升光催化性能的途径及其增强机制进行阐述，其中与Ag₃PO₄形成异质结构是目前提升其光催化性能的最主流的方法，Ag₃PO₄与金属氧化物、卤化物、硫化物、有机半导体、单质金属形成的异质结构均有效改善了其光催化性能，最后还对Ag₃PO₄基光催化剂未来的发展趋势进行了展望。
