摘要

摘要: 近年来，低温等离子体协同催化技术被认为是具有前景的VOCs降解技术之一。从现有研究结果来看，催化剂可显著提高VOCs降解效率，但不同催化剂的作用以及机理存在差异。因此，有必要深入了解等离子体与催化剂相互作用的研究进展。经过等离子体处理后的催化剂能提高吸附性能、产生热活化和抗积碳性等，同时催化剂还能改变等离子体的放电类型、增强局部电场和活性粒子的产生等。因此，文章主要综述光催化剂、贵金属催化剂、过渡金属氧化物催化剂等3种催化剂的研究进展，等离子体协同催化机理，催化剂与等离子体之间的相互影响。最后，基于当前研究现状对该技术的发展趋势进行了讨论与展望。

Abstract: In recent years， non-thermal plasma synergistic catalyst technology has been considered as one of the most promising technologies for VOCs degradation. Based on existing research results， catalysts can significantly improve the degradation efficiency of VOCs， but the effects and mechanisms of different catalysts vary. Therefore， it is necessary to have a deeper understanding of the research progress on the interaction between plasma and catalysts. After plasma treatment， the catalyst can improve adsorption performance， thermal activation capability， and carbon deposition resistance. At the same time， the catalyst can also modify the plasma discharge mode， enhance the local electric field， and promote the generation of active particles. Therefore， this paper maily reviews the research progress on three types of catalysts： photocatalysts， precious metal catalysts， and transition metal oxide catalysts. Furthermore， it examines the plasma-catalytic synergistic mechanism， along with the mutual effects between catalysts and plasma. Finally， based on current research， the development trends and future prospects of this technology are discussed. The research should focus on decomposing multi-component gas pollutants using plasma technology， aiming to enhance pollutant removal efficiency while inhibiting the formation of by-products. At present， low-temperature-plasma-modified catalysts have been studied. Future work sould combine these catalysts with plasma technology for VOCs degradation， investigating their synergistic effects and mechanisms.
