摘要
磷酸银(Ag3PO4)光催化剂的量子产率高达90％,在可见光照射下具有极强的光催化活性,但是Ag3PO4存在光腐蚀严重、光生电子和空穴寿命短等缺点,限制了其在生活实际的应用.本文首先介绍了 Ag3PO4光催化剂的结构特点、制备方法与反应机理,然后着重评述了通过形貌调控、贵金属沉积、负载、构建半导体异质结等方法改善Ag3PO4的光催化性能以及在降解污染物、光催化制氢、光催化还原CO2中的应用,最后指出目前关于Ag3PO4光催化剂研究中仍存在的不足,对Ag3PO4光催化剂未来的发展趋势进行展望.
Abstract
The quantum yield of silver phosphate(Ag3PO4)photocatalyst is as high as 90％,and it has very strong photocatalytic activity under visible light irradiation.However,Ag3PO4 has the disadvantages of serious photo corrosion,short lifetime of photogenerated electrons and holes,which makes its practical application to life limited.This paper first introduces the structural characteristics,preparation methods and reaction mechanism of Ag3PO4 photocatalyst,then emphatically reviews the improvement of the photocatalytic performance of Ag3PO4 by means of morphology regulation,precious metal deposition,loading,construction of semiconductor heterojunction,and its application in pollutant degradation,photocatalytic hydrogen production,and photocatalytic reduction of CO2.Finally,it points out that there are still shortcomings in the current research on Ag3PO4 photocatalyst,The future development trend of Ag3PO4 photocatalyst was prospected.
