N2 - Cu-based mixed oxides were investigated for WGSR in order to identify catalysts with high activity and durability even under severe conditions including a large amount of H2O in the reformed fuels. CuAl2O4 and CuMn2O4 showed much higher specific rates of CO conversion than Cu/ZnO/Al2O3. Although WGSR activity emerged from reduction of the mixed oxides, high-temperature reduction gave rise to the sintering of Cu. CuAl2O4 showed moderate CO oxidation activity at lower temperatures and WGSR activity over 300 °C. The CuMn2O4 catalyst exhibited high WGSR activity over 225 °C, comparable to that of Cu/ZnO/Al2O3, and high durability for 20h at 200-225 °C.
