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.
