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.
