Provided is a catalyst for producing hydrogen, which catalyst has higher performance than conventional catalysts since, for example, it exhibits a certain high level of activity in an aqueous formic acid solution at high concentration even without addition of a solvent, amine andor the like. One or more delete notifications are generated identifying the one or more portions of the multiple files. Accordingly, different interfacial adhesion and bulk rheology are generated at the interface of the first portionfirst, lamination layer and the interface of the second portionsecond lamination layer.
