Hydrogen peroxide synthesis.

摘要

This invention relates to improvements in palladium-carbon catalysts for the production of hydrogen peroxide from a mixture of hydrogen and oxygen in the presence of an aqueous liquid capable of inhibiting the decomposition of hydrogen peroxide. The improvement comprises using a catalyst wherein the carbon base is non-graphitic and has a surface area greater than 400 m<2>/g and wherein the palladium catalyst is prepared by impregnating the carbon base with a soluble palladium compound, drying the thus-impregnated carbon base and reducing the palladium compound with which the carbon base is impregnated to palladium with hydrogen at 40-140 DEG C.
