过渡金属磷化物在过去的几年中受到了极大的关注，因为它们是地球上丰富的，成本效益高，并在几个电化学驱动的转化，包括析氢，析氧和水裂解中显示出出色的催化性能。作为过渡金属磷化物的一员，考克斯磷基材料作为电催化剂已经得到了广泛的研究，但其在传统热催化方面的应用却鲜有报道。本工作设计了磷化钴/碳纳米立方体催化剂，并研究了其对硝基芳烃选择性加氢合成苯胺的催化活性。高表面积的金属有机框架（MOF）ZIF-67注入了红磷，然后热解促进了磷化物基催化剂的容易生产。所得的复合材料，由Co2 P/CNx纳米立方体，显示出优异的催化性能，在选择性氢化硝基芳烃苯胺。据我们所知，这是首次报道磷化钴在硝基芳烃加氢中的催化活性。
Transition-metal phosphides have received tremendous attention during the past few years because they are earth-abundant, cost-effective, and show outstanding catalytic performance in several electrochemically driven conversions including hydrogen evolution, oxygen evolution, and water splitting. As one member of the transition-metal phosphides, Cox P-based materials have been widely explored as electrocatalyts; however, their application in the traditional thermal catalysis are rarely reported. In this work, cobalt phosphide/carbon nanocubes are designed and their catalytic activity for the selective hydrogenation of nitroarenes to anilines is studied. A high surface area metal-organic framework (MOF), ZIF-67, is infused with red phosphorous, and then pyrolysis promotes the facile production of the phosphide-based catalysts. The resulting composite, consisting of Co2 P/CNx nanocubes, is shown to exhibit excellent catalytic performance in the selective hydrogenation of nitroarenes to anilines. To the best of our knowledge, this is the first report showing catalytic activity of a cobalt phosphide in nitroarenes hydrogenation.
