This study introduces a new and previously unconsidered fast abiotic formation of Mn(iv) oxides. We report photochemically assisted fast abiotic oxidation of Mn2+ (aq) to Mn(iv) (s) by superoxide radicals generated from nitrate photolysis. This photochemical pathway generates randomly stacked layered birnessite (δ-MnO2) nanosheets.
