Catalyst support materials of this technology exhibit both attrition resistance and desired support characteristics such as surface area and pore volume. Catalytic activity and selectivity is further enhanced by the addition of varying amounts of metal to the support. The procedure can comprise one or more repetitions of the impregnation of porous solid particles with an aqueous solution of metal salt. The wet solids are then calcined in a furnace with or without a controlled atmosphere. The ceramic support is coated with an aqueous solution of a salt from one of the metals of Ni, Pt, Pd, Ru, Rh, Cr, Co Mn, Mg, K, La, and Fe to fabricate a ceramic support particle that can convert metal salts to metal oxides. The resulting catalyst material is used as a steam reforming catalyst. This may require reduction in the presence of hydrogen first.
