The invention relates to a method for producing a catalyst. A layer consisting of catalytically active metallic material is deposited on a flat substrate by means of electrodeposition, said substrate being immersed in an electrolyte containing the catalytically active metallic material and an electrical , voltage is applied between the substrate and a counter-electrode. A high overvoltage at which a number of nuclei of the metallic material are formed on the substrate is applied between the substrate and the counter-electrode for a predetermined first period of time. The overvoltage is the reduced to a value at which the nuclei that were deposited during the first period grow on the …

Why it's free to use
- Filed March 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 14, 2020.
