挥发性有机化合物（VOCs），尤其是氯代挥发性有机化合物（Cl-VOCs），由于其挥发性、扩散性和毒性等特性，对人类健康和生态环境构成严重威胁，被认为是主要的污染物。催化降解挥发性有机物和氯代有机物是一种很有前途的方法，以减轻挥发性有机物和氯代有机物所造成的问题。低温等离子体（NTP）辅助催化是一种高效降解VOCs和氯代VOCs的新技术，与传统的热催化相比，在相对温和的条件下具有更高的选择性。本文从催化剂的设计、深度催化降解和副产物抑制策略以及NTP催化降解VOCs机理的基础研究三个方面综述了等离子体催化降解VOCs的研究现状。由于其较高的稳定性和毒性的特性，也特别注意Cl-VOC。本论文的每一章都对氯代挥发性有机化合物的降解催化剂、氯代副产物的形成以及氯代挥发性有机化合物的降解机理进行了系统的综述。最后，展望了NTP辅助VOCs催化降解技术的发展前景。
Most of the volatile organic compounds (VOCs) and especially the chlorinated volatile organic compounds (Cl–VOCs), are regarded as major pollutants due to their properties of volatility, diffusivity and toxicity which pose a significant threat to human health and the eco-environment. Catalytic degradation of VOCs and Cl–VOCs to harmless products is a promising approach to mitigate the issues caused by VOCs and Cl–VOCs. Non-thermal plasma (NTP) assisted catalysis is a promising technology for the efficient degradation of VOCs and Cl–VOCs with higher selectivity under relatively mild conditions compared with conventional thermal catalysis. This review summarises state-of-the-art research of the in plasma catalysis (IPC) of VOCs degradation from three major aspects including: (i) the design of catalysts, (ii) the strategies of deep catalytic degradation and by-products inhibition, and (iii) the fundamental research into mechanisms of NTP activated catalytic VOCs degradation. Particular attention is also given to Cl–VOCs due to their characteristic properties of higher stability and toxicity. The catalysts used for the degradation Cl–VOCs, chlorinated by-products formation and the degradation mechanism of Cl–VOCs are systematically reviewed in each chapter. Finally, a perspective on future challenges and opportunities in the development of NTP assisted VOCs catalytic degradation were discussed.
