Nickel cobalt oxide catalyst used for hydrolysis of sodium borohydride and preparation method of catalyst

The invention discloses a novel catalyst nickel cobalt oxide (NiCo2O4) used for preparing hydrogen by hydrolysis of sodium borohydride and a preparation method of the catalyst. A compound type catalyst is introduced into the field of hydrogen preparation by the sodium borohydride for the first time, and the catalyst can be used alone in various forms and can be used in a loading manner. The methodsynthesizes the nickel cobalt oxide/molecular sieve catalyst by using a molecular sieve as a carrier and a homogeneous precipitation method; and the method concretely comprises the following steps: (1) dissolving a cobalt source, a nickel source, and urea into deionized water to form a solution A; (2) adding the molecular sieve into the solution A to form a solution B; (3) placing the solution Binto an oil bath of 80-130 DEG C, performing stirring for a plurality of hours, and performing suction filtration to obtain a solid C; and (4) sintering the solid C at the temperature of 300-400 DEG Cfor a plurality of hours t
