摘要
实现有机污染物(VOCs)高效清洁降解是生态环保领域亟待解决的问题。光催化技术成为解决VOCs的有效方法之一,TiO_(2)半导体光催化剂作为最成熟的一种光催化剂,具有催化效率高、绿色、成本低的特点,但由于TiO_(2)光量子效率低,电子—空穴对易复合,无法产生可见光响应等缺陷,使得TiO_(2)光化材料无法广泛高效的应用。文章综述了改性TiO_(2)基光催化材料降解VOCs的研究进展,介绍了TiO_(2)光催化降解VOCs的作用机理,梳理归纳并总结了近些年TiO_(2)光催化降解VOCs的改性研究,并对未来开发新型TiO_(2)基光催化材料降解VOCs提出展望。
The efficient and clean degradation of organic pollutants(VOCs)is an urgent problem to be solved in the field of ecological protec-tion.Photocatalysis technology has become one of the effective methods to solve VOCs.As the most mature photocatalyst,TiO_(2) semiconductor photo-catalyst has the characteristics of high catalytic efficiency,green,and low cost.However,due to the low photoquantum efficiency of TiO_(2),easy elec-tron-hole pair composite,unable to produce visible light response and other defects,TiO_(2) photochemical materials cannot be widely and efficiently applied.This paper reviewed the research progress of VOCs degradation by modified TiO_(2)-based photocatalytic materials,introduced the mechanism of TiO_(2) photocatalytic degradation of VOCs,sorted out and summarized the modification research of TiO_(2) photocatalytic degradation of VOCs in re-cent years,and put forward the prospect of developing new TiO_(2) photocatalytic materials for VOCs degradation in the future.
