Hydrogen energy has long been recognized as a clean alternative to conventional fossil fuels, which can be applied in a wide range of transportation and power generation applications. The rational design and engineering of high-performance and robust catalysts for hydrogen evolution reaction (HER) shows not a great significance but a challenge for efficient electrochemical water splitting. Herein, a new type of Ni-based Ni-ABDC precursor has been obtained, which leads to the formation of N-doped porous carbon nanomaterials uniformly coated with well-proportioned bimetallic AgNi alloys via a stepwise strategy. To their credit, all samples of AgNi/NC-X are structurally calcined from the pristine AgNi-ABDC-X by tuning the different concentration of AgNO₃, which means all of them maintain the vermicelli-like morphology compared with Ni-ABDC. The series of AgNi/NC-X materials can be regarded as effective electrocatalysts for HER both in acidic and alkaline media, but an acid-leaching phenomenon is observed. Among them, the as-prepared AgNi/NC-2 exhibits a low overpotential of 103 mV at the current density of 10 mA cm⁻² and decent durability with a high retention rate of 90.9% after 10 h in 1.0 mol L⁻¹ KOH electrolyte. The compelling HER properties of AgNi/NC-2 can be attributed to the synergistic effect between the hierarchical carbon materials, partial N-doping and abundant AgNi alloys. Meanwhile, this study provides a practicable method for the development of efficient HER electrocatalysts for energy applications, which can be conveniently prepared through the reasonable introduction of active components in the crystalline inorganic-organic precursors.

长期以来，氢能一直被认为是传统化石燃料的清洁替代品，可广泛应用于交通运输和发电等领域。用于析氢反应 (HER) 的高性能和稳健催化剂的合理设计和工程对高效的电化学水分解来说意义不大，但却是一个挑战。在此，获得了一种新型的 Ni 基Ni-ABDC前驱体，它通过逐步策略形成了均匀涂覆均匀的双金属 AgNi 合金的 N 掺杂多孔碳纳米材料。值得赞扬的是，所有AgNi/NC-X样品都是从原始AgNi-ABDC-X结构上煅烧而来的通过调整不同浓度的 AgNO _{3 ，这意味着与}Ni-ABDC相比，它们都保持了粉丝状形态。AgNi/NC-X系列材料在酸性和碱性介质中均可被视为 HER 的有效电催化剂，但观察到酸浸出现象。其中，所制备的AgNi/NC-2在 10 mA cm ^-2的电流密度下表现出 103 mV 的低过电位和良好的耐久性，在 1.0 mol L ^-1 KOH中 10 小时后保留率为 90.9%电解质。AgNi/NC-2引人注目的 HER 特性这可以归因于多级碳材料、部分 N 掺杂和丰富的 AgNi 合金之间的协同效应。同时，该研究为开发用于能源应用的高效HER电催化剂提供了一种可行的方法，可以通过在结晶无机-有机前驱体中合理引入活性成分来方便地制备。
