Abstract:
A new type of solid acid catalyst, which promises better catalytic performance than conventionally prepared supported metal oxides due to its precisely synthesized nanostructure has been described. The catalyst is nanoparticulate in form and is comprised of monolayers of tungstated zirconia of the formula, WOxZryO4-2y made by impregnating a support with zirconium and tungsten. The support catalyst is further characterized in having a tugsten monolayer between greater than 0001 W/nm2 to about 30 W/nm2.
