Abstract
Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic microenvironment‐oxidation pathway relations remain significant challenges in Fenton‐like chemistry. Herein, incorporating sulfur heteroatoms into the higher coordination shell of FeN 4 structure (Fe‐NSC) exhibited a volcano trend of p ‐hydroxybenzoic acid oxidation, aligning with the number and positions of sulfur dopant. Specifically, higher shell S coordination with moderate electronegativity and larger atomic radii triggers long‐range electronic interactions, which provoke Fe 3d orbital splitting and spin electron rearrangement, resulting in a spin crossover with orbital states d xy 2 d yz 1 d xz 2 d…
