Patent ID: 8871617

Claim:
A method for forming a metallic film comprising two different metals on a substrate in a reaction space, the method comprising: depositing a mixed metal oxide comprising a first metal and a second metal on the substrate, wherein the first metal is different from the second metal and the mixed metal oxide comprises a greater concentration of the first metal than the second metal and wherein the mixed metal oxide film is not a film in which distinct and separate layers of metal oxides are observable; and reducing the mixed metal oxide by heating the substrate in a hydrogen atmosphere, wherein the first metal is selected from the group consisting of Ni, Fe, Co, Cu, Ag, Cr, V, Mn, Zn, Sn, Pb, Bi, In and Cd; and wherein the second metal is selected from the group consisting of Pt, Ni, Pd, Rh, Ru, and Co.
