摘　　要：钛酸锶钡(BST)作为一种半导体材料可被应用于光催化领域,但其对可见光的响应率低且光生载流子易复合,需要通过不同方法进行改性。BST是具有压电效应的半导体,可以通过其自身的压电效应形成的内建电场来提高光生载流子的分离效率,进而提升自身的光催化性能。通过光压协同、调控组成、元素掺杂等方法改性后,BST可被应用在光催化分解水制氢、降解污染物等领域。通过梳理学者在BST方面的研究成果,总结概述了BST的制备过程、压电光催化的机理以及BST在光催化领域的研究进展。As a semiconductor material,barium strontium titanate(BsT)can be used in the field of photocatalysis,but its response to visible light is low and the photogenerated carriers are easy to recombine,so it needs to be modified by using different methods.BST is a semiconductor with piezoelectric effect,which can be used to increase the separation efficiency of photogenerated carriers through the built-in electric field,thereby improving photocatalytic performance.After being modified through light pressure synergy,adjusting composition,element doping and other methods,BST can be used for photocatalytic water splitting to produce hydrogen and degrading pollutants.The preparation process of BST,the mechanism of piezoelectric photocatalysis,and the research progress of BST in the field of photocatalysis of BST will be summarized and discussed.
