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.

我们开发了一种复杂且可控的双还原剂策略，通过使用软模板定向组装方法合成具有可调节成分的介孔镍钴硼（NiCoB）非晶合金球（AAS）。选择性使用四丁基溴化膦（Bu4PBr）有利于生成轮廓分明的中孔。我们的内消旋 Ni10.0Co74.5B15.5 AAS 对氨硼烷 (AB) 的水解脱氢具有最高的催化性能。其高性能归因于Ni、Co和B之间的最佳协同效应以及开放介孔带来的高表面积和良好的传质效率。
