Metal oxide support material containing nanoscaled iron platinum group metal

A process for the preparation of a metal oxide support material comprising a nanoscaled iron-platinum group metal, the process comprising:

• (i) dissolving a precursor of the iron-platinum group metal and a polymer in water and/or an organic solvent,
• (ii) reducing the precursor of the iron-platinum group metal, optionally adding a reducing reagent, and
• (iii) combining the solution obtained in (ii) with a metal oxide support material
• wherein the polymer is selected from derivatized polyethyleneimines or polyvinylamines, linear or cross linked homo- and/or copolymers of vinyl lactams, vinylimidazoles, vinylacetates, or vinyl formamides, linear or cross linked graft-homo and/or graft-copolymers of vinyl lactams, vinylimidazoles, vinylacetates, or vinyl formamides on polyether;
• and
• wherein the precursor is selected from the group consisting of a salt of hydroxides, oxides, phosphates, sulfates, sulfites, phosphonites, nitrites, borates, aluminates, silicates, cyanides, isocyanates, thioisocyanates, perchlorates, periodates, perbromates, chlorates, iodates, bromates, hypochlorites, acetylacetonates, acetates, or amine complexes.
