中文摘要：
首次通过化学还原法制备了纳米多孔Co-Ni-B/Cu-BTC复合材料,在Co-Ni-B合金中掺入金属框架化合物Cu-BTC后有效地提高了复合材料的比表面积,其形貌由团聚的纳米粒子变成纳米多孔结构,复合材料的催化性能也得到显著的提高,用于催化氨硼烷的水解,表现出良好的催化活性。在30℃时,催化水解氨硼烷制氢的反应速率到达2670mL/（min·g）,其水解反应的活化能为22.4kJ/mol,与文献相比,表现出较大的优势。所制备的复合材料还具有良好的化学稳定性,表现出重要的应用前景。
英文摘要：
In this paper,nanoporous Co-Ni-B/Cu-BTC catalyst has been firstly prepared by in-situ chemical re-duction under sonication.After the introduction of Cu-BTC particles in Co-Ni-B alloy,the specific surface area of the composite was substantially improved.The morphology was also changed from aggregated nanoparticles to nanoporous structure.Furthermore,the catalytic activity of composite was enhanced greatly for the hydroly-sis of NH3BH3.A high rate of hydrogen generation has been monitored at 2 670 mL/（min·g）at 30 ℃ in NH3 BH3 solution.The activation energy of the hydrolysis 22.4 kJ/mol is obtained.The preparation of compos-ite has good chemical stability and has also been explored.
