摘　　要：实验采用一步化学沉积法,制备非贵金属CoM基纳米催化材料,同时采取控制变量法,改变了泡沫铜金属片在沉积时镀液中Co/Mo的摩尔比。并且把所制得的催化剂用于催化硼氢化钠(NaBH4)制氢,比较不同体系中产出氢气量,除以泡沫铜上生成催化剂的质量,得出析氢速率。得出该体系催化剂的最佳Co/Mo摩尔比。结果表明:当水浴温度为25℃、且镀液积淀时间为3 min时,Co/Mo摩尔比为1∶1时催化剂的催化效果最好。对NaBH4水解的产氢速率达到8 938.5 mL·min^(-1)·g^(-1)。The non-noble metal COM-based catalytic materials were prepared by one-step chemical deposition method. Meanwhile, the control variable method was used to change the molar ratio of Co to Mo in the deposition solution of the foam copper sheet. The hydrogen evolution rate was obtained by comparing the amount of hydrogen produced in different systems and dividing by the mass of catalyst generated on the copper foam. The best Co/Mo molar ratio of the catalyst was obtained. The results showed that when the bath temperature was 25 ℃, the bath deposition time was 3 min,and the molar ratio of Co to Mo was 1∶1,the best catalytic effect was achieved. The hydrogen production rate of NaBH4 hydrolysis reached 8938.5 mL·min^(-1)·g^(-1).
