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.
