Abstract

The present invention relates to the preparation of supported nanocomposite catalysts of noble metals and not and alloys thereof, by means of low-temperature heat treatments. They consist of one or more elements among which platinum, palladium, gold, ruthenium, rhodium, osmium, silver, iridium, nickel, copper, etc. and are employed in the chemical industry of catalysis being particularly useful in fuel cells for oxidation of a fuel at the anode and reduction of oxygen at the cathode where, as known, high reaction kinetics are required to convert chemical energy into electric energy.
