Operando high-resolution visible spectroscopy for Fe oxide covered FTO as working electrode (a, b) in KOH (pH 14). Each amperometry and its related high-resolution visible spectroscopy is in the same color (see Fig. S4 for setup). Two schematic proposed mechanisms for OER by Fe oxide under alkaline conditions (c).
