The Cu–Mo–B catalyst in nanostructure was synthesized with the chemical reduction method of sodium borohydride (NaBH4). The categorization of the attained Cu–Mo–B nano-catalyst was investigated with XRD, BET, SEM, and EDS analytical methods. As a result of the ammonium borane hydrolysis of this attained catalyst, the most convenient Mo/Co ratio, NaOH impact, the impact of different catalyst amounts, and the impact of different ammonium borane concentrations on ammonium boron hydride hydrolysis were evaluated. Additionally, hydrolysis was studied at different temperatures, and the degree and activation energy of the reaction were determined. At 333 K with the ammonium borane (AB) hydrolysis of Cu–Mo–B nanoparticles, the maximum hydrogen production rate and activation energy were 4075 mL/min-gcat−1 and 21.37 kJ/mol, respectively.
