Abstract
This review focuses on the research progress in the nickel-based catalysts for dielectric barrier discharge (DBD) assisted catalysis of CO2 methanation in the past ten years,including the catalyst activity under different plasma process parameters,and the influences of catalyst activation mode,support,additives,and other experimental conditions on the catalytic effect.The synergistic effect and reaction mechanism of plasma and catalyst in CO2 methanation assisted by DBD are revealed.Finally,a new prospect is proposed for the challenges of the DBD plasma-assisted catalysis system.
