Abstract

The present invention concerns a process for the production of hydrogen peroxide by reacting a gas mixture which contains hydrogen and oxygen in an aqueous reaction medium containing less than 2% by volume liquid organic components and in the presence of a metallic catalyst which is characterized in that a palladium/gold alloy with 5 to 95 atom percent gold or a palladium/iridium or palladium/rhodium bimetal with 1 to 15 atom percent iridium or rhodium is used as the catalyst.
