Two-dimensional graphdiyne analogue Co-coordinated porphyrin covalent organic framework nanosheets as a stable electrocatalyst for the oxygen evolution reaction

Abstract

Employing metalloporphyrin as monomer is an effective strategy to overcome the drawback of graphdiyne in electrocatalytic process. The Co–N4 active centers, expanded pores, and conjugated structure altogether endow the Co-PDY with excellent OER catalytic performance.
