Non-thermal plasma (NTP) catalysis has attracted widespread attention in volatile organic compounds (VOCs). Combining NTP with heterogeneous catalyst has been proved to reduce the formation of unwanted by-products and improve the energy efficiency of the process. The mechanisms of interaction with plasma and catalyst and VOCs oxidation in plasma catalysis are particularly hot research topic. This paper reviewed the mechanism of non-thermal plasma catalysis on volatile organic compounds removal. In the first part, the interaction between plasma and catalyst is disscussed. And the different catalysis systems and discharge types are presented in the second part. In the third part, attention is given to the influence of critical parameters on the removal processes. Finally, based on a large number of literatures, an extended review is presented detailly on the treatment of VOCs with plasma-catalysis system including the oxidation pathways. Moreover, future works of this promising technology are discussed.

非热等离子体（NTP）催化已引起挥发性有机化合物（VOC）的广泛关注。已证明将NTP与非均相催化剂结合使用可减少不需要的副产物的形成并提高过程的能源效率。在等离子体催化中与等离子体和催化剂相互作用以及VOCs氧化的机理是特别热门的研究主题。本文综述了非热等离子体催化去除挥发性有机物的机理。在第一部分中，讨论了等离子体与催化剂之间的相互作用。第二部分介绍了不同的催化体系和排放类型。在第三部分中，注意关键参数对去除过程的影响。最后，根据大量文献，详细介绍了使用等离子催化系统（包括氧化途径）对VOC的处理方法。此外，还讨论了这项有前途的技术的未来工作。
