| 英文摘要 | Fe2O3 is supposed to be one of the most promising photoanode materials. In terms of charge collection and transfer efficiencies, one-dimensional nanostructure arrays exhibit superior performance with great application potential in different fields. In the articles, Fe2O3 nanorod arrays (Fe2O3NRA) have been fabricated on the conductive fluorine-doped tin dioxide glasses by the hydrothermal method, In2O3 with different times cycles anchored Fe2O3NRA photoelectrode was also prepared by a simple dip-coating process. The structure, morphology, crystalline and optical property of the as-prepared photoelectrode were characterized by X-ray diffraction, Raman spectra, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy, etc. The photoelectrochemical performance of the samples was investigated under visible light irradiation. A highest photocurrent density of 23 ?A/cm2 at 1.23 V (versus the reversible hydrogen electrode) is obtained for the In2O3 with 4 times cycle anchored Fe2O3NRA photoelectrode in a 1 M Na2SO4 aqueous solution. The maximum applied bias photon-to-current efficiency is observed for the In2O3 with 4 times cycle anchored Fe2O3NRA photoelectrode with values 0.0033%. The results indicated that the appropriate decoration amount of In2O3 nanoparticles significantly hinders the recombination process of electron-hole pairs and improves the separation efficiency of photogenerated charge carriers of Fe2O3NRA. |
