摘　　要：以泡沫镍(NF)为镍源和载体,采用水热法在其表面原位合成纯NiSe。扫描电镜表明NiSe以蜂窝状覆盖在泡沫镍表面。分别在自然环境以及电场作用下研究了NiSe/NF片催化溶液中水合肼氧化性能,结果表明,NiSe/NF片表现出较高的催化活性和循环稳定性能。该NiSe/NF片所具有的制备简易、降解液便于分离以及较高的活性和稳定性等特点,使其在含水合肼的废水的快速检测与降解以及催化制氢等方面都有较好的应用前景。NiSe was prepared on the surface of Nickel foam(NF)by hydrothermal method with nickel foam and Selenium powder as raw material.SEM indicated that the black coating on the NF surface is pure NiSe crystal with honeycomb-like interwoven morphology.The catalytic performance of NiSe/NF sheet for hydrazine oxidation was investigated respectively at natural environment and under the action of electric field.The results shows that NiSe/NF exhibits good catalytic activity and stability performance.With the advantages of simple preparation,easy separation from degradation solution,high activity and stability,The NiSe/NF piece has a good application prospect in the rapid detection and degradation of wastewater containing hydrazine hydrate and catalytic hydrogen production.
