Cobalt sulfide nanoparticles impregnated nitrogen and sulfur co-doped graphene as bifunctional catalyst for rechargeable Zn–air batteries

Author affiliations

Abstract

We report cobalt sulfide nanoparticles decorated nitrogen and sulfur co-doped graphene nanosheets as an effective bifunctional oxygen catalyst. Its oxygen evolution reaction (OER) catalytic activity outperforms Pt/C, giving a current density of 38.19 mA cm−2 at 1.0 V. Zn–air batteries using this material on air-cathode show high stability and good rechargeability.
