    • Method for the direct synthesis of an aqueous solution of hydrogen peroxyde from hydrogen and oxygen by hydrogenous catalysis in a three-phase system in which the hydrogen and oxygen are reacted directly in a gas state, at a pressure above atmospheric pressure, on the surface of a solid hydrogenous catalyst in suspension in a granular state in an aqueous liquid phase, said catalyst consisting of a metal compound selected from pure palladium or an association of palladium with at least one other noble metal, and impregnated on a substrate comprising at least one compound selected from alkaline-earth metal sulfates or phosphates. A catalyst is disclosed for the production of an aqueous liquid phase of hydrogen peroxyde consisting of a metal compound selected from pure palladium or an association of palladium with at least one another noble metal, and impregnated on a substrate comprising at least one compound selected from alkaline-earth metal sulfates or phosphates. A method of preparing the catalyst by precipitation of the palladium or palladium mixture with at least one other noble metal on the granular substrate is also disclosed.
