Co-B amorphous-state alloy porous microspherical catalyst used for hydrogen release through ammonia borane alcoholysis and preparation method for Co-B amorphous-state alloy porous microspherical catalyst

The invention relates to a binary amorphous-state alloy porous microspherical type efficient catalyst used for hydrogen release through catalytic alcoholysis of a hydrogen storage material ammonia borane and a preparation method for the binary amorphous-state alloy porous microspherical type efficient catalyst. A chemical formula of the catalyst can be abbreviated as CoxB(1-x), wherein a molar ratio of Co to B is x to (1-x), and x ranges from 0.15 to 0.85. The catalyst has an unformed amorphous-state phase structure, has an uniformly dispersed microspheric appearance, has a microsphere size ranging from 200 nm to 300 nm, is distributed with micropores in surface, and has a specific surface area ranging from 45 m .g to 60 m .g; a liquid-phase chemical process is adopted, the process is relatively simple and convenient, a high-temperature high-pressure reaction and treatment process is involved, time is relatively short, control is easy, and environmental pollution is avoided in a preparation process; a
