Abstract: An amorphous alloy catalyst with adjustable ratio of different components in the bimetallic catalyst was prepared by adding tartaric acid ligand.The synthesized Ni-Fe-B-ta bimetallic nanoparticles were characterized.And the Ni-Fe-B-ta had an estimated Langmuir surface erea of 100.54m2/g.The catalytic activity was also studied by catalyzing hydrogen hydrolysis of sodium borohydride.The experimental results shown that the addition of tartaric acid to the catalysts of both metals greatly improved the ability of NaBH4 to produce hydrogen,and the maximum hydrogen production rate at room temperature reached 7300mL/(min·g) with an activation energy of 46.0kJ/mol.The cyclic test results shown that after 3 repeated catalytic tests,the catalyst can still maintain a high catalytic activity.
