Beta-Fe2O3 nanoparticle-assembled film for photoelectrochemical water splitting
Since Fe2O3 is a promising photoanode material for water splitting, it has attracted much attention, while other phases of ferric oxide are ignored. Here, β-Fe2O3 was used as photoanode material for solar water splitting. The crystal structure and phase of β-Fe2O3 was characterized by X-ray diffraction, X-ray photoelectron spectroscopy, Raman scatter, Mössbauer spectra and Superconducting Quantum Interference Device. The photocurrent density of β-Fe2O3 photoanode at 1.6 VRHE was 0.12 mA•cm-2 under the illumination of simulated sunlight (AM1.5G, 100mW•cm-2).
