Catalysts of the instant invention are made by reducing a catalyst precursor comprising a support phase impregnated with one or more elemental transition metals, wherein: (a) the support phase is formed by dispersion of a monolayer on the surface of a high surface area alumina support; and (b) the monolayer comprises XOnYO2, where (1) XOn is a redox active metal oxide and n is either 1.5, 2, or 2.5 depending on the oxidation number of X, and (2) YO2 is a redox inactive metal oxide. Ni—V2O5—ZrO2/Al2O3 catalysts of the instant invention are preferred.Type: GrantFiled: February 20, 2003Date of Patent: August 10, 2010Assignees: University of Iowa Research Foundation, Honda Motor Co., Ltd.Inventors: Darrell P.
