Representative work: Abstract Selective oxidation of CH bonds is one of the most important reactions in organic synthesis. However, activation of the α‐CH bond of ethylbenzene by use of photocatalysis‐generated superoxide anions (O 2 •− ) remains a challenge. Herein, the formation of individual Fe atoms on polymeric carbon nitride (CN), that activates O 2 to create O 2 •− for facilitating the reaction of ethylbenzene to form acetophenone, is demonstrated. By utilizing density functional theory and materials characterization techniques, it is shown that individual Fe atoms are coordinated to four N atoms of CN and the resultant low‐spin Fe–N 4 system (t 2g 6 e g 0 ) is not only a great adsorption site for oxyge Developing cost-efficient electrocatalysts for oxygen evolution is vital for the viability of H2 energy generated via electrolytic water. Engineering favorable defects on the electrocatalysts to provide accessible active sites can boost the sluggish reaction thermodynamics or kinetics. Herein, Co1–x S nanosheets were designed and grown on reduced graphene oxide (rGO) by controlling the successive two-step hydrothermal reaction. A belt-like cobalt-based precursor was first formed wit
