Electrochemical hydrogen production is greatly limited by the low efficiency, high cost, and poor stability of electrocatalysts. Here, we report a facile one-step method to synthesize nitrogen, phosphorus co-doped carbon encapsulated FeP/CoP derived from dual metal-organic frameworks (FeP/CoP@NPC). Thanks to the synergistic effect of its unique composition and structure, the resultant FeP/CoP@NPC shows excellent catalytic HER performance with low potentials of 198, 286, and 339 mV to achieve a current density of 10 mA cm in acidic, neutral, and alkaline media along with remarkable long-time durability, respectively. More importantly, this work provides an efficient strategy for fabricating high-performance and stable pH-universal catalysts toward hydrogen generation.
电化学制氢受到电催化剂效率低、成本高和稳定性差的极大限制。在此,我们报道了一种简便的一步法,用于合成由双金属有机框架衍生的氮、磷共掺杂碳包覆的FeP/CoP(FeP/CoP@NPC)。由于其独特组成和结构的协同效应,所得的FeP/CoP@NPC在酸性、中性和碱性介质中分别具有198、286和339 mV的低电位,展现出优异的催化析氢性能,能够实现10 mA cm的电流密度,同时还具有显著的长期耐久性。更重要的是,这项工作为制备高性能且稳定的pH通用型析氢催化剂提供了一种有效策略。
