    Abstract: The effect of TiO 2 layer applied to the conventional Fe 2 O 3 /FTO photoanode to improve the photoelectrochemical performance was assessed from the viewpoint of the microstructure and energy band structure. Regardless of the location of the TiO 2 layer in the photoanodes, that is, Fe 2 O 3 /TiO 2 /FTO or TiO 2 /Fe 2 O 3 /FTO, high performance was obtained when α -Fe 2 O 3 and H-TiNT/anatase-TiO 2 phases existed in the constituent Fe 2 O 3 and TiO 2 layers after optimized heat treatments. The presence of the Fe 2 O 3 nanoparticles with high uniformity in the each layer of the Fe 2 O 3 /TiO 2 /FTO photoanode achieved by a simple dipping process seemed to positively affect the performance improvement by modifying the energy band structure to a more favorable one for efficient electrons transfer. Our current study suggests that the application of the TiO 2 interlayer, together with α -Fe 2 O 3 nanoparticles present in the each constituent layers, could significantly contribute to the performance improvement of the conventional Fe 2 O 3 photoanode.
