摘要：
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. © 2020, High Voltage Engineering Editorial Department of CEPRI.
