Abstract Key to CO 2 reduction transformation is the development of catalysts that efficiently activate inert molecules, enabling rapid reaction kinetics with minimal energy inputs. In this study, we introduce N‐confused porphyrin (NCP) as a highly active ligand scaffold for transition metal‐based in reactions. By breaking D 4h symmetry inherent conventional structures, NCP promotes enhanced electron delocalization around corresponding metal complex, improving catalytic efficiency. A comprehensive study demonstrates NCP‐based complexes (Fe, Co, and Ni) significantly outperform their parent metal‐porphyrin counterparts.
