New Functional Ceramic Membranes Using Nanoporous Metals

我们开发了一种复杂且可控的双还原剂策略，通过软模板指导组装的方法合成了组成可调的介孔镍钴硼(NiCoB)非晶态合金球(AASS)。选择性地使用四丁基溴化膦(Bu4PBr)有利于生成定义良好的介孔。我们的介孔分子筛Ni10.0Co74.5B15.5对氨基硼烷(AB)的水解脱氢反应具有最高的催化性能。它的高性能归功于Ni、Co和B之间的最佳协同效应以及由于开放的介孔而具有的高比表面积和良好的传质效率。

We develop a sophisticated and controllable dual-reducing agent strategy to synthesize the mesoporous nickel–cobalt boron (NiCoB) amorphous alloy spheres (AASs) with adjustable compositions by using a soft template-directed assembly approach. The selective use of tetrabutylphosphonium bromide (Bu4PBr) is beneficial to generate well-defined mesopores. Our meso-Ni10.0Co74.5B15.5 AASs generate the highest catalytic performance for the hydrolytic dehydrogenation of ammonia borane (AB). Its high performance is attributed to the combination of optimal synergistic effects between Ni, Co, and B as well as the high surface area and the good mass transport efficiency due to the open mesopores.
