Abstract

Seeking electrocatalysts with a low Pt content, high activity, and durability in oxygen reduction reaction (ORR) remains one major challenge for fuel cell applications. Herein, by chemical dealloying of AlCoPt ternary alloys, CoO nanosheets with evenly doped ultrasmall Pt clusters/nanoparticles have been obtained. Thanks to the coherent atomic structure between CoO and Pt, the Pt-doped CoO (Pt/CoO) can work stably for ORR in 0.1 M HClO4 after tens of thousands of electrochemical cycles and exhibits a 13.5-fold enhancement in the electrochemically active surface area normalized ORR activity over that of commercial Pt/C catalyst.
