摘要
钒酸铋(BiVO_(4))具有带隙窄、光稳定性高、毒性低、绿色环保等优点,已经成为了一种光响应良好的催化剂.但是,BiVO_(4)的电子-空穴复合速度快,使得BiVO_(4)的光催化活性低,限制了它的应用.近些年来,科研人员在合成方法的改进和催化剂结构的调变等方面,做了很多工作来抑制BiVO_(4)电子-空穴复合.本文主要综述了BiVO_(4)催化剂的合成方法,以及多金属氧酸盐(POMs)/BiVO_(4)和金属-有机框架(MOFs)/BiVO_(4)复合催化剂在光催化降解有机污染物、光电催化分解水和光催化氧化脱硫等性能的研究进展情况.同时,对BiVO_(4)类催化剂的研究现状和前景进行了总结和展望,为后续BiVO_(4)类催化剂的研究提供了理论基础.
Bismuth vanadate(BiVO_(4))is one kind of excellent photoresponsive catalyst possessing several advantageous properties,including narrow band gap,high photostability,low toxicity,and environmental friendliness.However,the practical applications of BiVO_(4)were limited due to the rapid recombination of electrons and holes,resulting in diminished photocatalytic activity.In recent years,some works in mitigating electron-hole recombination of BiVO_(4)through enhanced synthesis techniques and structural modulation of catalysts have been done by researchers.This paper reviews the various synthesis methods for BiVO_(4)catalysts as well as the advancements of POMs/BiVO_(4)and MOFs/BiVO_(4)composite catalysts,concerning photocatalytic degradation of organic pollutants,photocatalytic water splitting,and photocatalytic oxidative desulfurization.Additionally,we summarize the current research status and look into the future prospects of BiVO_(4)catalysts,which can provide a theoretical foundation for subsequent investigations.
