High‐Performance Electrocatalysts for Oxygen Reduction Derived from Cobalt Porphyrin‐Based Conjugated Mesoporous Polymers

Abstract

A cobalt-nitrogen-doped porous carbon that exhibits a ribbon-shape morphology, high surface area, mesoporous structure, and high nitrogen and cobalt content is fabricated for high-performance self-supported oxygen reduction electrocatalytsts through template-free pyrolysis of cobalt porphyrin-based conjugated mesoporous polymer frameworks.
