制备了一种高稳定性和高活性的硼化镍催化剂(NixB)，并对碱性NaBH4溶液进行了催化水解试验。结果表明，经150℃真空热处理后的NixB催化剂具有较高的催化活性和操作稳定性。在实验条件下，该反应在45℃时可产生6.75wt%的氢气，在室温下也能产生4.0wt%的氢气，其储氢容量远高于目前使用的储氢合金。由于NixB催化剂价格低廉，易于制备，因此将该催化剂用于便携式和现场应用的实际氢气发生器是可行的。(C)2003年国际氢能协会。爱思唯尔科学有限公司出版。版权所有。
A highly stable and active nickel boride catalyst (NixB) was prepared and tested for the catalytic hydrolysis of alkaline NaBH4 solution. It was found that after heat treatment at 150degreesC in vacuum the NixB catalyst shows greatly enhanced catalytic activity and operational stability. In the experimental conditions, the hydrolysis reaction can produce 6.75 wt% hydrogen at 45degreesC and > 4.0 wt% hydrogen even at room temperatures, exhibiting much higher hydrogen storage capacity than currently used alloys for hydrogen storage. Since the NixB catalyst is inexpensive and easy to prepare, it is feasible to use this catalyst in the construction of practical hydrogen generators for portable and in situ applications.
