Carbon dioxide (CO2) is a greenhouse effect gas and contributes much to global warming, the reduction and sequestration of CO2 has been attracting interest from an environmental perspective. The CO2 reforming by CH4 is an attractive process to produce a syngas. But it is a highly energy consuming and coke forming process. To solve these problems, Electrocatalytic internal reforming of CO2 by CH4 was suggested in previous works. The CO2 reforming by CH4 over Ni-based catalyst was investigated to check the possibility of development of a high performance catalyst electrode for application in an electrocatalytic reforming in the SOFC system. The catalysts before and after the reaction were characterized by X-ray diffraction (XRD), N2 physisorption and CO chemisorption. It was found that Ni-YSZ-CeO2 catalyst is a promising candidate for development as a catalyst anode material for an electrocatalytic reforming in the SOFC system. |
