In situ preparation of MOF-derived Fe2O3 nanorods for visible-light-driven oxygen evolution

Fe 2 O 3 nanorods were in situ synthesized in ambient air at room temperature by oxidation of Fe-based MOFs, which possess a high photocurrent density up to 0.11 mA cm −2 and exhibit an outstanding oxygen evolution rate efficiency of 55.2 μmol g −1 h −1 .
