Correction: Lee, S.; Park, J.-W. Hematite/Graphitic Carbon Nitride Nanofilm for Fenton and Photocatalytic Oxidation of Methylene Blue. Sustainability 2020, 12, 2866

The authors would like to make the following correction to the published paper [1]. The change is as follows:

The XRD peak structure of α-Fe₂O₃/g-C₃N₄ in Figure 3 has been revised. Accordingly, the original Figure 3:

Figure 3. X-ray diffraction (XRD) pattern of bare fluorine-doped tin oxide (FTO), β-FeOOH, α-Fe2O3, and α-Fe2O3/g-C3N4.

Has been replaced with the corrected version, the corrected Figure 3 appears below:

Figure 3. X-ray diffraction (XRD) pattern of bare fluorine-doped tin oxide (FTO), β-FeOOH, α-Fe₂O₃, and α-Fe₂O₃/g-C₃N₄.

Figure 3. X-ray diffraction (XRD) pattern of bare fluorine-doped tin oxide (FTO), β-FeOOH, α-Fe₂O₃, and α-Fe₂O₃/g-C₃N₄.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
