Abstract:
A method for synthesizing a catalyst which reforms a methane gas into a hydrogen gas efficiently at a relatively low temperature comprising a palladium deposition step in which a manganese dioxide having a ramsdellite-type crystal structure is immersed in a palladium-containing aqueous solution to allow the palladium to be deposited on the surface of said manganese dioxide, and a heat treatment step in which said manganese dioxide having the palladium deposited thereon is heated under a reducing atmosphere to change said manganese dioxide to a manganese oxide Mn3O4 having the palladium carried thereon.
