摘要：PROBLEM TO BE SOLVED: To provide a hydrogen producing catalyst having a long catalytic life in the decomposition of a hydrocarbon such as methane, a manufacturing method thereof and a hydrogen manufacturing method using the catalyst. SOLUTION: The hydrogen producing catalyst contains a carrier comprising silica, titania, a graphitized carbon fiber or a carbon nanofiber and palladium and nickel supported on the carrier. The manufacturing method of the hydrogen producing catalyst includes a process for immersing silica, titania, graphitized carbon fiber or a carbon nanofiber becoming the carrier with a solution of a nickel compound and a palladium compound, and a process for drying the impregnated carrier. According to circumstances, a baking process or a reducing process using a reducing gas can be contained. The hydrogen manufacturing process contains a process for decomposing a hydrocarbon in the presence of the catalyst. COPYRIGHT: (C)2004,JPO
