20 mol% samarium doped cerium oxide has a superior ionic conductivity than 8 mol% yttria stabilized zirconia commercially available in Solid Oxide Fuel Cell (SOFC). In this study, a sample coated on Ni/YSZ by doping with Co, Ni and Pd in addition to SDC is applied to the methane dry reforming reaction. After synthesizing a coating solution using colloidal Ce, coating was performed 10 times for the desired thickness. For surface analysis of the synthesized catalyst, BET and XPS analysis were performed. The TEM and SEM image confirmed whether the coating on Ni/YSZ was successful. Then, through gas chromatograph analysis and EIS electrical performance measurement, it was confirmed how the SDC coating and additionally doped metal materials affected the DRM reaction. As a result, As a result, SDCCN@Ni/YSZ doped with Co and Ni showed 90% methane conversion at 700°C and the highest electrochemical performance at 850°C, 56 mW/cm2. |
