Boosting oxygen reduction activity with low-temperature derived high-loading atomic cobalt on nitrogen-doped graphene for efficient Zn-air batteries

Abstract

High-loading atomic cobalt (12.8 wt%) dispersed on nitrogen-doped graphene was successfully synthesized via considerably low temperature pyrolysis. The catalyst exhibits excellent electrocatalytic performance towards oxygen reduction reaction with large limiting diffusion current density of 5.60 mA cm-2 (10% higher than that of commercial Pt/C), and when acting as the air catalyst of Zn-air batteries, a high open-circuit voltage of > 1.40 V and excellent power density are also achieved.
