合理设计具有中空结构的金属介孔纳米结构为提高其在各种催化领域的性能提供了有效的途径。在这里，我们报道了一种简单的两步法制备三金属空腔PtPdCo介孔纳米多面体(PtPdCo MHNPs)的方法，其中Pd@PtPdCo核壳介孔纳米多面体(Pd@PtPdCo MHNPs)是通过简单的化学还原反应直接制备的，然后对Pd核进行刻蚀。PtPdCo MHNPs由于其介孔和中空的纳米结构与三金属组成相结合，表现出更高的电催化活性和对甲醇氧化反应的耐久性。
The rational design of metallic mesoporous nanoarchitectures with hollow cavities offers an effective way to boost their performance in various catalytic fields. Herein, we report a facile two-step strategy for the fabrication of trimetallic PtPdCo mesoporous nanopolyhedra with hollow cavities (PtPdCo MHNPs), in which Pd@PtPdCo core–shell mesoporous nanopolyhedra (Pd@PtPdCo MNPs) are directly prepared by a simple chemical reduction reaction followed by etching of the Pd cores. The PtPdCo MHNPs show enhanced electrocatalytic activity and durability for the methanol oxidation reaction, enabled by their mesoporous and hollow nanoarchitectures coupled with trimetallic compositions.
