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。

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.
