Preparation of colloidal dispersion of nickel, palladium and platinum by the polymer-catalyzed decomposition of carbonyl compounds thereof

摘要: There is disclosed a method for the preparation of homogeneous, physically stable dispersion colloidal metal particles transition selected from group consisting nickel, palladium and platinum having size in range about 10 Angstrom units to 200 units. The comprises preparing solution functional polymer an inert solvent, incrementally adding thereto precursor, at temperature which precursor will become bound thermally decompose produce elemental particles, process being carried out atmosphere. Such dispersions may be used per se as catalysts, or supported catalysts. also ablative optical recording media.
