This review introduces the technical principle of dielectric barrier discharge (DBD) plasma coupled catalytic oxidation of VOCs,and explores the coupling mode and synergistic effect.The oxidation mechanism of VOCs by various types of catalysts is investigated under plasma-catalysis system,with emphasis on the enhanced mechanism of the morphology and structure of catalysts.It is suggested that morphology regulation and microstructure construction are helpful to enhance the specific surface area of catalyst and promote the formation of active sites.The development direction of the plasma coupled catalytic oxidation of VOCs is predicted.
