The alloy catalyst formed by transition metal and a small amount of noble metal has become the most promising substitute for M-based (M = Pt, Pd, Ru, Rh) catalyst. However, due to the direct exposure of the metal core to the electrolyte, it is vulnerable to corrosion and oxidation, which in turn reduces the catalytic stability and is becoming a major obstacle to sustainable hydrogen production. The present work addresses this issue by developing a one-step immersion-adsorption-pyrolysis strategy for synthesizing FeM alloy nanoparticles with N-doped carbon coatings (FeM@CN) for use as electrocatalysts in the HER. The deliberately designed metal-organic framework material was used as the precursor of catalyst synthesis to achieve the carbon coatings and simultaneously the heteroatom in-situ doping for the alloy nanoparticles. The optimal FePt@CN demonstrates excellent catalytic stability and HER activity in an acidic electrolyte medium. The reactions obtain a small overpotential of 28 mV to achieve current densities of 10 mA cm⁻², which are comparable to a high-performance commercial Pt/C electrocatalyst with a much higher Pt loading. The FeRu@CN also demonstrates an outstanding performance with an overpotential of only 18 mV to achieve a current density of 10 mA cm⁻² in an alkaline medium.

由过渡金属与少量贵金属形成的合金催化剂已成为最有前途的M基（M= Pt、Pd、Ru、Rh) 催化剂。然而，由于金属核直接暴露在电解质中，容易腐蚀和氧化，进而降低催化稳定性，成为可持续制氢的主要障碍。目前的工作通过开发一种一步浸渍-吸附-热解策略来合成具有 N 掺杂碳涂层 (FeM@CN) 的 FeM 合金纳米粒子，用作 HER 中的电催化剂，从而解决了这个问题。精心设计的金属有机骨架材料用作催化剂合成的前体，以实现碳涂层，同时原位掺杂合金纳米颗粒。最佳的 FePt@CN 在酸性电解质介质中表现出优异的催化稳定性和 HER 活性。^-2，可与具有更高 Pt 负载量的高性能商业 Pt/C 电催化剂相媲美。FeRu@CN 还表现出出色的性能，在碱性介质中实现 10 mA cm ^-2的电流密度的过电位仅为 18 mV 。
