开发了一种氢氧化钠辅助还原方法来控制负载在纳米多孔碳 Maxsorb MSC-30 上的超细无表面活性剂双金属 NiPt 纳米颗粒 (NP) 的合成。该催化剂首次在室温下发挥极高的催化活性，将肼硼烷（HB）100%选择性转化为氢气。这种非常简便有效的还原方法为超细合金纳米粒子提供了强有力的切入点，以充分利用贵金属并实现增强的性能，其中合金的成分可以进行广泛的调整和定制。此外，催化结果为HB作为有前景的储氢材料的有效应用开辟了新途径。
A sodium-hydroxide-assisted reduction approach has been developed to control the synthesis of ultrafine surfactant-free bimetallic NiPt nanoparticles (NPs) supported on nanoporous carbon, Maxsorb MSC-30. For the first time, this catalyst exerts exceedingly high catalytic activity for 100% selective conversion of hydrazine borane (HB) to hydrogen at room temperature. This remarkably facile and effective reduction approach provides a powerful entry into ultrafine alloy NPs to make full use of noble metals and achieve enhanced performance, where the compositions of the alloy can be widely adjusted and tailored. Moreover, the catalytic results open up new avenues in the effective application of HB as a promising hydrogen storage material.
