Generation of hydrogen by sodium borohydride solution had attracted lots of attention. A serial of nanosized NiB catalysts were prepared using the chemical reduction method through introducing AlCl3 into the preparation. Catalytic performance of NiB catalysts were investigated in the hydrolysis of alkaline NaBH4 solution. The catalysts were characterized by X-ray diffraction (XRD), N2 adsorption, Transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results showed that NiB catalysts possessed amorphous alloy structure, and the particle size could be adjusted by the AlCl3 amount. Catalytic performance showed that NiB catalyst with smaller particle size had much higher activity. The NiB catalyst also displayed high stability, the catalytic activity could retain about 84% of its initial value after four cycles.

使用纳米 NiB 非晶合金催化剂水解硼氢化钠制氢

硼氢化钠溶液制氢引起了人们的广泛关注。采用化学还原法通过引入AlCl制备了一系列纳米NiB催化剂3进入准备阶段。NiB催化剂在碱性NaBH水解中的催化性能研究4解决方案。催化剂通过 X 射线衍射 (XRD)、N2吸附、透射电子显微镜 (TEM) 和 X 射线光电子能谱 (XPS)。结果表明，NiB催化剂具有非晶合金结构，粒径可以通过AlCl2调节。3数量。催化性能表明，粒径较小的NiB催化剂具有更高的活性。NiB催化剂也表现出较高的稳定性，四次循环后催化活性可以保持在初始值的84%左右。
