A Bimodal-Pore Strategy For Synthesis Of Pt3co/C Electrocatalyst Toward Oxygen Reduction Reaction Dagger

A bimodal-pore strategy was developed for preparation of the Pt3Co/C catalyst with active Pt3Co nanoparticles located around the mass transfer channels rather than inside them, which leads to ca. 29% higher mass transfer efficiency and a superior single-cell performance under an ultralow Pt loading.
