Novel synthesis methods such as solvothermal decomposition, colloidal crystal templating, and reverse microemulsion have been used to prepare CeO2-supported Co catalysts. These catalysts have shown much better catalytic performance than the catalysts prepared using conventional incipient wetness impregnation for Ethanol Steam Reforming. The improvement can be attributed to a better cobalt dispersion and a better Co-CeO2 interaction for the catalysts prepared using these novel methods.
