CATALYST FOR REFORMING OF METHANE GAS INTO HYDROGEN, METHOD FOR SYNTHESIS OF THE CATALYST, AND METHANE GAS REFORMING METHOD USING THE CATALYST

摘要

A method for synthesizing a catalyst that can convert a methane gas into a hydrogen gas with high efficiency at a relatively low temperature, which comprises: a palladium precipitation step of immersing manganese dioxide having a ramsdellite-type crystal structure with a palladium-containing aqueous solution to cause the precipitation of palladium on the surface of the manganese dioxide; and a heating treatment step of heating the manganese dioxide having palladium precipitated thereon in a reductive atmosphere to convert the manganese dioxide into manganese oxide Mn₃O₄ having palladium supported thereon.
