Abstract The direct methanol fuel cell, one of the most promising energy sources for portable devices and transportation applications, has attracted great attention in recent years. However, the high cost and insufficiency of Pt and the CO poisoning phenomenon during the electrocatalysts considerably inhibited the commercialize usage. Therefore, the synthetic methodology of geometrically and electronically optimized nanocatalyst has been studied. Herein, we introduce the synthesis of hierarchical Ru branched RuPtCu nanocages through the co-reduction of Ru, Pt, and Cu precursors, following the injection of additional Ru precursors. The electrochemical tests show that the catalytic activity and stability of hierarchical Ru branched RuPtCu nanocages for methanol oxidation is much higher than those of RuPtCu/C, PtCu/C, the commercial PtRu/C, and Pt/C catalysts.
