A bimodal-pore strategy for synthesis of Pt3Co/C electrocatalyst toward oxygen reduction reaction

Abstract

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.
