低温等离子体-催化协同净化技术是一种理想的环境污染治理技术。催化剂的加入可提高等离子体反应中污染物的脱除效率和二氧化碳的选择性,减少副产物的产生,并进一步降低能耗。分析了低温等离子体-催化协同净化挥发性有机化合物的效果与净化原理,并从影响污染物降解率的因素、产物分析和反应动力学等机理性研究方面概括了目前国内外在应用该技术去除挥发性有机污染物方面取得的成果,最后提出了该项技术在环境保护领域的应用前景以及研究方向。

Catalysis-assisted non-thermal plasma is an ideal technology for pollution control. Catalyst could enhance pollutants removal efficiency and selectivity to carbon dioxide in the plasma reaction, inhibit by-products formation and lower energy consumption. In this paper the synergetic effects and （principle of catalysis-assisted non-thermal plasma technology in decomposition of volatile organic compounds （VOCs） were discussed. Advances in decomposition of volatile organic compounds （VOCs） using catalysis-assisted non-thermal plasma technology were l：eviewed, including the factors influencing decomposition efficiency, products distribution and reaction kinetics. The prospects for application of this technology in the field of environmental protection and trends of development were discussed, too.
