(a) Proposed two parallel pathways for direct methane oxidation to methanol in the aqueous media using H2O2 as the oxidant. (b) A posed molecular mechanism for the direct oxidation of methane to methanol over a mononuclear Fe5+=O active site. Red, purple, gray, and white spheres represent O, Fe, C, and H atoms, respectively. Adapted with permission from ref (308). Copyright 2021 American Chemical Society.
