METHOD FOR PRODUCING A CATALYST

摘要

The invention relates to a method for producing a catalyst. Catalytically active material is electrochemically deposited onto a substrate, whilst the substrate is immersed in an electrolyte containing the catalytically active material. A voltage is applied between the substrate and a counter-electrode , whereby the catalytically active material is deposited onto a metal substrat e whilst the substrate which is to be coated is subjected to current or voltag e pulses of a predetermined amplitude and/or frequency, and whereby the catalytically active material is directly and immovably fixed to the substra te.
