Abstract Coordination structure engineering represents a promising approach for optimizing the catalytic properties of single‐atom catalysts (SACs). However, precise tailoring sites remains challenging. Herein, pre‐coordination strategy is proposed to design SACs with tunable local coordination environments on 2D honeycomb‐like carbon nanofoams. By pre‐coordinating metal precursor customized functional groups layered Mg(OH) 2 template through strong d‐p orbital hybridization, featuring Co─N 4 (Co 1 /NC), Co─C /CC), and S /CSC) configurations are fabricated. The lamellar architecture facilitates active site exposure, reactant enrichment, mass transfer during reaction process. Consequently, Co /NC catalyst, despite its extremely low loading 0.12 wt.%, demonstrates exceptional activity stability nitroaromatics reduction, achieving an impressive overall turnover frequency (TOF) 73668 h −1 conversion 4‐nitrophenol 4‐nitroaniline, surpassing most reported catalysts. Theoretical calculations indicate configuration possesses moderate Fermi electronic states compared , significantly promoting formation utilization reactive H * species accelerating kinetics aromatic nitroreduction. This work establishes novel avenue meticulous manipulation structures in SACs, paving way advancement sophisticated materials chemical transformations.
