摘　　要：随着人们生活水平的提高,室内空气质量越来越受到关注。挥发性有机物(VOCs)是影响室内空气质量的有害气体。因此,对于室内VOCs的有效去除已经成为空气治理中的研究热点。TiO_(2)光催化剂具有光转换和无二次污染等特点被广泛应用于治理VOCs领域中。然而其在可见光范围内的响应较弱和光生电荷载流子的分离效率低等问题,限制了其光催化降解效果。对TiO_(2)进行改性处理是当下改善其光催化作用的必要手段。简单介绍了TiO_(2)光催化的基本原理,基于光催化原理概述影响TiO_(2)光催化性能的因素,对近年TiO_(2)的改性设计研究进行归纳总结,同时表明了TiO_(2)降解室内VOCs具有广阔的应用前景。With the improvement of people s living standards,indoor air quality is a growing concern.Volatile organic compounds(VOCs)are harmful gases that affect indoor air quality.Therefore,the effective removal of indoor VOCs has become a hot research topic in air treatment.Titanium dioxide(TiO_(2))photocatalysts are widely used in the field of VOCs treatment because of their light conversion and no secondary pollution.However,its weak response in the visible light range and low separation efficiency of photogenerated charge carriers limit its photocatalytic degradation effect.The modification of TiO_(2)is a necessary means to improve its photocatalytic effect nowadays.This paper briefly introduced the basic principles of TiO_(2)photocatalysis,outlined the factors affecting the photocatalytic performance of TiO_(2)based on the photocatalytic principles,summarised the recent research on the modification design of TiO_(2),and showed that the TiO_(2)degradation of indoor VOCs had a broad application prospect.
