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

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.
