In this study, we report the successful preparation of hematite nanostructures coated with thin titania layer for potential solar water splitting applications. The prepared samples were studied systematically by a range of analysis techniques. We showed that resulting hybrid hematite-titania nanosystem exhibited improved photoelectrochemical activity for solar water splitting compared to the bare hematite only. We also showed that this enhancement was achieved through an improvement in light harvesting and better charge carrier separation. Thus, these findings may open new perspectives for the development of photoelectrodes used in photoelectrochemical water splitting applications.
