The promoted Ni-Ce0.8Zr0.2O2 catalysts have been applied to low temperature steam reforming of methane (SRM) reaction. The metal oxides (La2O3, CaO, and MgO) were introduced as a promoter to Ni-Ce0.8Zr0.2O2 catalysts. Among the prepared catalysts, the Ni-La2O3-Ce0.8Zr0.2O2 catalyst exhibited high activity as well as stability for the SRM reaction, even at a high GHSV of 621,704 h-1. The remarkable catalytic performance of the Ni-La2O3-Ce0.8Zr0.2O2 catalyst is mainly ascribed to the high Ni dispersion and proper interaction between Ni and La2O3. |
