摘　　要：采用浸渍与化学还原相结合的方法,制备了一系列CoB/ZSM-5非晶态合金负载型催化剂,考察其在硼氢化钠水解制氢中的催化活性。结果表明,CoB/ZSM-5负载型催化剂具有高的催化活性,30℃时NaBH4水解产氢速率为1.3 L/(min·g),表观活化能为54.4 kJ/mol,大大低于粉末状非晶态CoB催化剂的活化能(71.4 kJ/mol)。Amorphous CoB/ZSM-5 alloy supported catalysts were prepared via a eombined impregnation and ehemieal reduetion method,and their catalytie aetivities were investigated in hydrogen produetion from the hydrolysis of NaBH4 . The result showed that CoB/ZSM-5 supported catalyst exhibits much higher catalytie activity compared with unsupported powdered CoB catalyst. The hydrogen generation rate of CoB/ZSM-5 supported eatalysts reaeh about 1. 3 L/（min·g）. It was found that the aetivation energy for NaBH4 hydrolysis is caleulated to be 54. 4 kJ/mol based on CoB/ZSM-5 supported eatalysts whieh is obviously lower than unsupported powdered CoB eatalyst（71. 4 kJ/mol）.
