The facile preparation of platinum‐based catalysts with designed compositions and structures is of great importance for fuel cells. In this work, a one‐pot method is developed to synthesize monodispersed trimetallic PtPdCo mesoporous nanoparticles (PtPdCo MNs) with uniform morphology and size. The proposed synthetic method does not require any hard template or organic solvent, which greatly simplifies the preparation procedure. PtPdCo MNs, with a highly porous structure, exhibit enhanced electrocatalytic activities and excellent stabilities for both the formic acid oxidation reaction and the oxygen reduction reaction, relative to bimetallic PtPd MNs and commercial Pt/C catalyst. The proposed synthetic method is highly valuable for the design of mesoporous multimetallic catalysts for fuel cells.

三金属PtPdCo介孔纳米粒子增强的双燃料电池电催化

具有设计的组成和结构的铂基催化剂的简便制备对燃料电池非常重要。在这项工作中，开发了一种单罐方法来合成具有均匀形态和尺寸的单分散三金属PtPdCo介孔纳米粒子（PtPdCo MNs）。所提出的合成方法不需要任何硬模板或有机溶剂，从而大大简化了制备过程。相对于双金属PtPd MNs和市售Pt / C催化剂，具有高度多孔性的PtPdCo MNs表现出增强的电催化活性和优异的甲酸氧化反应和氧还原反应稳定性。所提出的合成方法对于燃料电池的介孔多金属催化剂的设计具有很高的价值。
