摘　　要：TiO2是一种常见的n型半导体材料,将TiO2与其他材料复合构成异质结能够拓宽TiO2光响应范围,减小光生空穴与光生电子重新结合的几率,提高整个体系的光电转换效率。主要对异质结作用于光催化的基本原理以及基于TiO2异质结在光电化学传感领域的应用做了相关综述。TiO2 is one kind of the common n - type semiconductor materials. Compounding TiO2 with other semiconductor materi- als to construct heterojunctions can broaden the light response of TiO2 , reduce the chance of recombining between photogenerated holes and electrons and improve the photovoltaie conversion efficiency of the whole system. This paper focuses on the basic prin- ciples of heterojunetions functioning on photocatalysis and makes a summary of the application in the photoelectrochemical sensing field of heterojunctions based on TiO2.
