Abstract Electrochemical conversion of carbon dioxide (CO 2 ) into value‐added products is promising to alleviate greenhouse gas emission and energy demands. Metalloporphyrin‐based covalent organic frameworks (MN 4 ‐Por‐COFs) provide a platform for rational design electrocatalyst CO reduction reaction RR). Herein, through systematic quantum‐chemical studies, the N‐confused metallo‐Por‐COFs are reported as novel catalysts RR. For MN ‐Por‐COFs, among ten 3d metals, M = Co/Cr stands out in catalyzing RR or HCOOH; hence, Por‐COFs with Co/CrN 3 C 1 centers designed. Calculations indicate CoN x y ‐Por‐COFs exhibit lower limiting potential (−0.76 ‐0.60 V) ‐to‐CO than its parent (−0.89 make it feasible yield deep‐reduction degree CH OH . Electronic structure analysis reveals that substituting /CoN increases electron density on Co‐atom raises d ‐band center, thus stabilizing key intermediates determining step lowering potential. similar reason, changing core from CrN /CrN lowers ‐to‐HCOOH reduction. This work predicts be high‐performance catalyst candidates. Inspiringly, proof‐of‐concept study, provides an alternative strategy coordination regulation theoretical guidelines catalysts.
