Abstract
The invention relates to a catalyst for hydrogen production through hydrolysis of sodium borohydride, in particular to a CoB / NF sodium borohydride hydrolysis catalyst as well as a preparation method and application thereof. The preparation method comprises the following steps: reacting cobalt chloride hexahydrate with sodium borohydride to prepare a CoB powder catalyst; mixing the CoB powder catalyst with a binder PVDF (Polyvinylidene Fluoride), and adding NMP (N-Methyl Pyrrolidone) to prepare slurry; and coating a foamed nickel supporting substrate with the slurry, and then carrying out annealing treatment to remove the NMP solvent so as to obtain the CoB / NF composite material. The preparation method is simple to operate and easy for large-scale production, and the prepared catalyst has excellent stability, high catalytic activity and lower preparation cost, and has a good application prospect in the field of hydrogen production through rapid hydrolysis of sodium borohydride.
