Ni0.6Cu0.4O/NC催化剂的制备及其催化氨硼烷水解制氢性能研究
Preparation of Ni0.6Cu0.4O/NC catalyst and its catalytic performance for hydrogen production from hydrolysis of ammonia borane
摘要
Abstract
Ammonia borane(NH3 BH3,AB)is an ideal feedstock with high hydrogen storage capacity.In this paper,nitrogen-containing carbon material(Ni0.6 Cu0.4 O/NC)catalyst was prepared by high-temperature carbonization of Ni/Cu-ZIF precursor under nitrogen atmosphere.The microstructure as well as the composition of the as-prepared catalyst were characterized.In addition,the catalytic performance of the catalyst were tested under reaction conditions.The results showed that the activation energy(Ea)for hydrolysis of AB over Ni0.6 Cu0.4 O/NC catalyst was 56.8 kJ/mol with TOF value as high as 1572.2 h-1.The hydrogen production could be approximated as a zero-order reaction with respect to the concentration of AB,and a one-order reaction with respect to the amount of catalyst.The catalyst still maintained good activity after ten cycles,indicating the good stability.关键词
