氮氧化物(NOx)与挥发性有机物(VOCs)是形成颗粒物(PM2.5)与臭氧(O3)的重要前体物,对人类健康造成严重危害。光催化氧化技术因其具有条件温和、节能高效、安全无毒等特点而受到越来越多的关注。目前,以TiO2为主的半导体光催化剂表现出独特的物理化学性质和优异的性能,成为当前大气污染控制领域的研究热点之一。综述了最新的光催化氧化技术在单独去除烟气NOx、VOCs以及共同去除NOx和VOCs方面的最新研究进展,重点关注了TiO2光催化剂和其他光催化剂的潜在作用,并解释了增强光催化活性的策略,如贵金属掺杂、非金属掺杂和半导体耦合等。此外,还回顾了光催化降解烟气NOx和VOCs的实验参数、去除效率及其降解机理等。该综述旨在总结分析以TiO2为主的半导体光催化材料开发的“结构-性能-应用”关系,为共同去除烟气NOx和VOCs的研究提供参数支持和优化建议,同时讨论新型催化剂的制备和改性途径,促进未来对光催化氧化共同去除NOx和VOCs的研究。

Nitrogen oxides (NO) and volatile organic compounds (VOCs) are significant precursorsto particulate matter(PM) and ozone (O), posing serious health hazards. Photocatalytic oxidationtechnology is gaining increasing attention due to its mild conditions, energy efficiency, safety, and non-toxic nature. Currently, semiconductor photocatalysts, primarily based on TiO, exhibit unique physi⁃cochemical properties and excellent performance, becoming a focal point in current research on atmos⁃pheric pollution control. This review summarizes the latest research progress in the photocatalytic oxida⁃tion technology for the individual and simultaneous removal of NO and VOCs, with a focus on the po⁃tential roles of TiO photocatalysts and other photocatalysts. It also explains strategies for enhancingphotocatalytic activity, such as noble metal doping, non-metal doping, and semiconductor coupling.Additionally, it reviews experimental parameters, removal efficiency, and degradation mechanisms forphotocatalytic degradation of flue gas NO and VOCs. This review aims to summarize the structure-per⁃formance - application relationship in the development of semiconductor photocatalytic materials,provide parameter support and optimization suggestions for research on the simultaneous removal of fluegas NO and VOCs, discuss new catalyst preparation and modification approaches, and promote futureresearch on the co-removal of NO and VOCs by photocatalytic oxidation.
