摘要：Exploring efficient and low-cost electrocatalysts toward oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is extremely desirable for the commercial application of rechargeable Zn-air battery. Herein, we developed a facile pyrolysis and hydrothermal method for in-situ immobilizing Mn3O4 onto chitosan-deriving Co induced N-doped carbon nanotubes (Mn3O4/NCNTs@Co). The obtained Mn3O4/NCNTs@Co nanohybrid expresses excellent activity for oxygen reversible electrocatalysis with a half-wave potential (E 1/2 ) of 0.85 V and a potential of 1.53 V at 10 mA cm-2. Furthermore, a home-made zinc-air battery with Mn3O4/NCNTs@Co catalyst shows a high open-circuit voltage (OCV) of 1.46 V and excellent cycling stability of nearly 1100 cycles at 5 mA cm-2. The outstanding electrocatalytic activities are comparable to those with commercial noble metal catalysts, ascribing to the synergistic integration among the Co, Mn3O4, and conductive carbon matrix. This work provides a promising route for the scalable preparation of biomass derived efficient metallic compound-carbon-based ORR/OER electrocatalysts. ? 2022, The Authors. All rights reserved.
