本研究在氮气气氛下高温碳化Ni/Cu-ZIF前驱体制备了一种含氮炭材料（Ni0.6Cu0.4O/NC）催化剂，并采用多种表征方法对所制备催化剂的微观结构以及组成成分进行了研究。此外，通过控制变量法探究了催化剂的催化性能以及变化规律。研究结果表明，Ni0.6Cu0.4O/NC催化AB水解制氢的活化能（Ea）为56.8 kJ/mol，TOF值高达1572.2 h−1。该催化剂催化AB水解制氢速率对于AB自身浓度可近似看作零级反应，而相对于催化剂的用量可近似看作一级反应。催化剂经过10次循环后仍然保持良好的催化活性，表明其具有良好的稳定性。

Ammonia borane (NH3BH3, AB) is an ideal feedstock with high hydrogen storage capacity. In this paper, nitrogen-containing carbon material (Ni0.6Cu0.4O/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 Ni0.6Cu0.4O/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.
