In this work, we introduce Fe and Ni into Co-MOF to construct a kind of multicomponent phosphide hollow architecture with walls assembled by nanosheets. The multicomponent nature can enhance the intrinsic catalytic activity, while the sheet-like surface and inter-sheet voids provide a large active area, which is beneficial for electrolyte penetration and gas generation. As expected, the optimized product has catalytic hydrogen evolution reaction (HER) overpotentials of 105 and 161 mV at current densities of 10 and 100 mA cm, respectively, and maintained long-term stability for over 100 hours at 10 mA cm current densities.
在本工作中，我们将铁和镍引入钴基金属有机框架中，构建了一种由纳米片组装而成壁的多组分磷化物空心结构。多组分特性可增强本征催化活性，而片状表面和片间空隙提供了大的活性面积，这有利于电解质渗透和气体生成。正如预期的那样，优化后的产物在电流密度为10和100 mA cm时，析氢反应（HER）的过电位分别为105和161 mV，并且在10 mA cm电流密度下保持了超过100小时的长期稳定性。
