A Ni-Fe/ceria-zirconia catalyst with ordered mesostructure was prepared by the hard-template method employing mesoporous silica (KIT-6) as a template to impart its highly ordered structure to the ceria-zirconia mixed oxide support. Catalytic activities of the Ni-Fe/CeO(2)-ZrO(2) catalyst for the water-gas shift reaction were superior to those of a commercial Fe-Cr-based catalyst. The ordered structure of Ni-Fe/CeO(2)-ZrO(2) catalyst became more stable compared to one prepared without zirconia due to structural stabilization of the mixed oxide by added zirconia in the framework. Alloying of Ni and Fe and enhanced mobility of lattice oxygen in the oxide support may promote its catalytic activity and selectivity for the water-gas shift reaction. (C) 2011 Elsevier B.V.
