Methanation with plasma catalysis attracts attention because it can promote the process at lower temperatures than conventional thermal catalysis. In this study, we aimed to improve methanation efficiency by combining plasma catalysis with the adsorption function of zeolite. As a result, molecular sieves significantly improved the CH4 yield. However, the effect of Ni-supported catalysts could not be confirmed. Under the conditions of this experiment, reverse reactions were found to be a major issue
