Abstract

A three dimensional (3D) N-doped porous graphene and vanadium nitride co-promoted Pt (3DNPG/VN/Pt) electrocatalyst was first presented in this work. Such multi-component catalysts exhibited superior performance for the oxygen reduction reaction (ORR). The mass activity of 3DNPG/VN/Pt is 535 mA mg⁻¹ Pt (after IR correction), which is 4.35 times as high as that of commercial Pt/C (123 mA mg⁻¹ Pt). Higher stability of 3DNPG/VN/Pt is also demonstrated in comparison with the commercial Pt/C.
