低温等离子体诱导的低温催化反应在污染控制和能源等领域的应用一直是等离子体化学研究的热点。本文综述了NTP与催化剂相互作用的实验观察和认识的最新进展。考虑到反应物种的扩散长度和寿命，我们引入了一个无量纲参数λ，它描述了NTP和催化剂之间的直接相互作用的标准。介绍了几种相互作用的实验证据：放电模式、金属团簇离子的形成和催化剂的等离子体诱导荧光。对于八面沸石，发现Si/Al比是决定表面流光传播和催化性能的重要参数。金属的氧化状态与Si/Al比密切相关，这与电阻率的实质性变化有关。(C)2015 Elsevier B.V.版权所有。
Low temperature catalytic reactions induced by nonthermal plasma (NTP) have been of great interest in plasma chemistry for application to pollution control and energy-related issues. Current progress in the experimental observations and the understanding of interactions between NTP and catalyst are reviewed herein. Considering the diffusion length and lifetime of reactive species, we introduced a dimensionless parameter Lambda that describes the criteria for a direct interaction between NTP and catalysts. Several lines of experimental evidences on the interaction were introduced: discharge mode, formation of metal cluster ions, and plasma-induced fluorescence from the catalyst. For faujasite zeolites, the Si/Al ratio was found to be an important parameter that determines the propagation of surface streamers and catalytic performance. The oxidation status of metals is closely correlated with the Si/Al ratio, which is related to substantial changes in electrical resistivity. (C) 2015 Elsevier B.V. All rights reserved.
