摘  要:This paper describes the performance degradation of impregnated catalyst in the dielectric barrier discharge (DBD) plasma-assisted methane conversion process. Mn and Ni mixed copper-zinc catalysts, and bare ��-Al<sub>2</sub>O<sub>3</sub> support were exposed to the DBD plasma generated at 1 kHz and 9 kV under CH<sub>4</sub> direct conversion for 4 hours. The performance degradation due to the surface damage of the catalyst by the plasma was investigated by SEM analysis.
