Facile Fabrication of Radial PtCo Nanodendrites for Enhanced Methanol Oxidation Electrocatalysis

To improve the catalytic performances of Pt-based catalysts toward the methanol oxidation reaction (MOR) and reduce the consumption of Pt, we report one-step facile fabrication of radial PtCo nanodendrites (NDs) by a modified solvothermal method. It is noticeable that the radial PtCo NDs have a Pt-rich surface, and the radial PtCo NDs possess more tip areas due to unique first level NDs and more interconnected second level NDs, which can facilitate electronic transmission and mass exchange. Compared with commercial Pt/C, the radial PtCo NDs catalyst shows enhanced catalytic performance and stability toward the MOR. More importantly, this study offers more opportunities to prepare bimetallic NDs with enhanced catalytic performance.
