The importance of methane reforming reactions is increasing due to the climbing demand of H2 and synthesis gas, which is the major feedstock for C1 chemistry and fuel cells. Reforming of methane with water or carbon dioxide is an important technology for the conversion of CH4 to H2 and syngas as chemical raw materials and fuel gas of solid oxide fuel cells. Herein, we invented a novel Pr-doped Ni/CeO2 catalyst for methane reforming with high activity and excellent coking-tolerance ability. The integration of this catalyst in a SOFC enables the direct utilization of nearly dry methane as the fuel with high electrochemical performances as well as significantly improved durability compared to the SOFC without the catalyst.
