Facile preparation of Fe2O3thin film with photoelectrochemical properties

We report a simple approach for preparing undoped and Pt-doped Fe2O3 thin films with excellent photoactivity via facile hydrothermal growth. The photocurrent densities of undoped and Pt-doped Fe2O3 thin films were recorded up to 1.2 and 1.38 mA cm−2 at 0.23 V Ag/AgCl under 1 sun illumination, respectively.
