The transition metal alloy nanoparticles (NPs) have received significant attention because of their unique physicochemical properties as well as low cost. Herein, we report a facile and clean synthetic route to prepare porous FeCo/C bimetallic alloy nanocomposites by using metal-organic gels (MOGs) as precursors. The bimetallic MOGs based on iron and cobalt bridged by tri-carboxylate organic ligands were first synthesized by a general and fast solvothermal method. The desired FeCo/C nanocomposites were then obtained by a one-step annealing process in which MOGs served as both the precursor and the self-sacrificing template. Significantly, the as-synthesized FeCo/C nanocomposites exhibit excellent catalytic activity and lithium-ion batteries performance. This fast and clean synthetic strategy is extended to synthesis diversity and range of potential applications of porous carbon-coated transition-metal alloy nanocomposites.
过渡金属合金纳米粒子（NPs）因其独特的物理化学性质和低成本而受到广泛关注。在此，我们报告了一种简便、清洁的合成方法，通过使用金属有机凝胶（MOGs）作为前体制备多孔 FeCo/C 双金属合金纳米复合材料。基于铁和钴的双金属 MOGs 通过三羧酸酯有机配体桥接，首先通过通用且快速的溶剂热法合成。然后，通过一步退火过程获得所需的 FeCo/C 纳米复合材料，其中 MOGs 既是前体又是自牺牲模板。重要的是，合成的 FeCo/C 纳米复合材料表现出优异的催化活性和锂离子电池性能。这种快速、清洁的合成策略可扩展到多孔碳涂层过渡金属合金纳米复合材料的多样性和潜在应用。
