Abstract (en)
[origin: WO03078056A1] The invention relates to heterogeneous catalysts which are particularly easy to produce. Said heterogeneous catalysts are generated by immobilizing preformed monometallic or multimetallic metal oxide particles in situ on an oxidic or non-oxidic carrier, wherefore metal oxide colloids which are stabilized by hydroxide ions and immobilized on carriers contained in the suspension are generated from conventional, water-soluble metal salts by means of hydrolysis and condensation. The inventive method makes it possible to produce fuel cell catalysts, for example.
