Nature-inspired high-spin Fe IV  = O generation enables efficient ambient methane oxidation. By engineering sulfur-bridged dual ≡Fe II …Fe II ≡ sites on pyrite (FeS 2 ) mimicking soluble methane monooxygenase, we achieve O 2 -driven formation of high-spin (S = 2) surface Fe IV  = O species at room t...
