Abstract
- Exploring economic, scalable, and highly efficient carbon materials for the oxygen reduction reaction (ORR) is of great significance to a variety of renewable energy conversion and storage technologies. Herein, we directly convert soya peptone as a carbon precursor to a series of mesoporous nanocarbon-based materials for the ORR via a one-step pyrolysis process combined with the help of ZnCl<subscript>2</subscript> as an activator. Benefiting from the effective chemical activation effect during carbonization, the optimal electrocatalysts possess mesoporous structures and high surface area (>1000 m<superscript>2</superscript> g<superscript>−1</superscript>) which favor fast mass transport, electron transfer, and exposure of abundant active sites. Remarkably, the electrocatalysts show a comparable ORR catalytic performance, excellent stability, and superior methanol tolerance, comparable to the commercial Pt/C catalyst. Thus, soya peptone biomass derived carbon materials are surely helpful for providing a new space to develop ORR electrocatalysts. [ABSTRACT FROM AUTHOR]
