Water oxidation is a key step and a bottleneck for large-scale energy storage in artificial photosynthesis. Herein Fe oxide on the surface of fluorine-doped tin oxide electrode was synthesized by a very simple, new and low-cost method, using the reduction of K2FeO4 in water. The electrode was characterized by scanning electron microscopy, transmission electron microscopy, energy dispersive spectrometry, X-ray diffraction, diffuse reflectance infrared Fourier transform spectroscopy and Raman spectroscopy. Such fluorine-doped tin oxide electrode could be used as stable water-oxidizing anodes at pH = 13 to yield current densities of 1 mAcm−2 at an overpotential of 550 mV.
