Metal-containing covalent organic frameworks (MCOFs), as a class of crystalline organic polymers with abundant single-atom metal sites, can respond effectively to various vital reactions, including hydrogen evolution reaction (HER), CO 2 reduction reaction (CO 2 RR), oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The advent of MCOFs provides a platform for the establishment of model catalysts with highly repetitive structure to facilitate theoretical calculations and high-throughput screening while designing flexibility in monomer construction to lay the foundation for the development of highly selective and active photo/electrocatalysts. In this review, we summarize the recent progress in this field and highlight several important MCOFs photo/electrocatalysts for OER, ORR, HER, and CO 2 RR. Moreover, various approaches are also mentioned to improve or optimize the catalysts and indicate the future research direction on enhancing the performance of MCOFs catalysts based on the current existing challenges.
