Photocatalysis has attracted wide attention in eliminating volatile organic compounds (VOCs). This paper pays attention to the relationship between structure and performance of photocatalysts based on the fact that catalytic reactions arise on the surface of catalysts and the interface structure of photocatalysts plays key role in transfer efficiency of charges carriers. This review summarizes various surface/interface designs including unsaturated coordination such as oxygen vacancies, surface halogenations, and heterojunctions, homojunctions, facets, etc., as well as the application in photocatalytic degradation of VOCs. This paper reviews the influence of surface and interface properties of materials on VOCs molecules, effective strategies to promote the decomposition of VOCs from the perspectives of VOCs activation, reaction barrier etc., and presents various methods of photocatalyst design appropriately. The degradation path of highly toxic benzene VOCs are also summarized. In addition, the possible problems and suggestions for photocatalytic degradation of VOCs are proposed.
光催化在消除挥发性有机化合物（VOCs）方面引起了广泛关注。本文基于催化反应发生在催化剂表面以及光催化剂的界面结构在载流子转移效率中起着关键作用这一事实，关注光催化剂的结构与性能之间的关系。本综述总结了各种表面/界面设计，包括不饱和配位（如氧空位、表面卤化和异质结、同质结、晶面等）以及在光催化 VOCs 降解中的应用。本文综述了材料表面和界面性质对 VOCs 分子的影响，从 VOCs 激活、反应势垒等方面提出了促进 VOCs 分解的有效策略，并适当提出了各种光催化剂设计方法。还总结了高毒性苯 VOCs 的降解途径。此外，还提出了光催化降解 VOCs 可能存在的问题和建议。
