摘要

空气中的挥发性有机物（VOCs）严重影响空气质量和人类健康

其排放需要得到控制。低温等离子体是一种有应用前景的先进VOCs净化技术。为此针对现有等离子体VOCs净化技术的能量效率低及纳米颗粒物副产物生成等问题的解决展开综述。首先介绍了介质阻挡放电产生的活性氧（臭氧）与脉冲电源的电压上升时间、氧气浓度之间的关系

然后综述了VOCs的分解机理及动力学特征、VOCs分解产生的纳米颗粒物副产物特征以及利用催化剂来降低纳米颗粒物副产物的排放和提高反应温度来提高能量效率

最后指出了低温等离子体催化技术的实际应用需要解决的研究课题。

Abstract

Volatile organic compounds（VOCs） in atmosphere seriously deteriorate air quality and human health

thus their emission should be controlled. Non-thermal plasma is one kind of advanced VOCs cleaning technologies of potential application. We summarize the solution for problems such as low energy efficiency and nano-particle by-product formation while using current VOCs plasma cleaning technologies. Firstly

the relation of reactive oxygen（ozone） with the rise time of pulse voltage from a pulse power supply and oxygen concentration is introduced; secondly

the mechanism of VOCs decomposition and kinetic features

nano-particle by-products from VOCs decomposition

and the use of catalysts for reducing nano-particle emission and the evaluation of reaction temperature for improving energy efficiency are summarized;finally

research subjects needed to be solved for the real application of non-thermal plasma-catalytic technologies are suggested.
