Volatile organic compounds (VOCs) are an important component of air pollutants. As a new technology, low temperature plasma technology has the advantages of low cost, simple structure, and wide applicability in processing VOCs. It has attracted widespread attention from scholars at home and abroad in recent years. VOCs components in industrial flue gas are often very complex and the degree of degradation is different. Therefore, in the laboratory simulation, it is necessary to increase the components of simulated exhaust gas and develop a dielectric barrier plasma co-catalysis technology that can deal with multiple components. The removal rate of VOCs is positively related to the discharge voltage and energy density of the reactor. The higher the voltage, the higher the removal rate. But it is accompanied by the increase in the production of NOx, O 3 and other byproducts. The type of medium has a great influence on the removal effect of VOCs. The cooperative catalytic removal of VOCs by dielectric barrier plasma is a complex physico-chemical process, and the current research on the reaction mechanism is incomplete.
