Abstract: The present invention relates to the technical field of catalysts, and discloses a yolk/shell-type CoxCu1-xCo2O4@CoyCu1-yCo2O4 catalyst as well as a preparation method and application thereof to catalytic hydrogen generation. The preparation method of the yolk/shell-type CoxCu1-xCo2O4@CoyCu1-yCo2O4 catalyst includes the steps of: successfully synthesizing, by applying a hydrothermal synthesis method, a [Co(C6H12N4)2](NO3)2 solid sphere complex from a cobalt salt and hexamethyleneteramine serving as an alkali source; and then, performing calcination to obtain a yolk/shell-type Co3O4 microsphere structure, adsorbing Cu2+ on a surface in a physical adsorption manner, and performing calcination again to form yolk/shell-type CoxCu1-xCo2O4@CoyCu1-yCo2O4. The preparation method is simple, raw materials are cheap and available, and the prepared yolk/shell-type CoxCu1-xCo2O4@CoyCu1-yCo2O4 catalyst is high in purity, good in catalysis performance and capable of showing excellent catalytic activity in term of ammonia borane catalytic hydrolysis for hydrogen generation.

Abstract: A device includes: a storage section which stores a solution containing an organic compound; a catalyst holding section to hold a solid catalyst; and a microwave irradiation mechanism which irradiates the solution passing through the catalyst holding section with a microwave, wherein the solid catalyst is a molded catalyst containing a noble metal supported on a carrier that has an average particle diameter larger than 100 μm. A hydrogen production method includes irradiating a solution containing an organic compound, the solution passing through a catalyst holding section holding a solid catalyst, with a microwave, the solid catalyst being a molded catalyst containing a noble metal supported on a carrier that has an average particle diameter larger than 100 μm. Both device and method do not require a high-temperature heat source, enable easy collection, replacement, of the catalyst, and can be used for production of hydrogen.
