Process for producing a catalyst layer on a carrier and a catalyst produced therefrom

摘要

The present invention relates to a process for producing a metallic catalyst layer or coating which serves for effectuating the removal of hydrogen from a gas mixture containing hydrogen and oxygen. The catalyst layer itself which is porous, comprises a metal, such as palladium (Pd) or platinum (Pt), or alloys of these metals, which catalytically influence the oxidation of hydrogen. The metal or the metal alloy is applied as a catalyst layer or coating onto a carrier material or substrate by either plasma spraying or flame spraying. The present invention also provides a catalyst through the intermediary of a catalyst layer which is produced in accordance with the process of the instant invention.
