Hydrothermal Grown Nanoporous Iron Based Titanate, Fe₂TiO₅ for Light Driven Water Splitting

We report the synthesis of iron based titanate (Fe₂TiO₅) thin films using a simple low cost hydrothermal technique. We show that this Fe₂TiO₅ works well as a photoanode for the photoelectrochemical splitting of water due to favorable band energetic. Further characterization of thin films including band positions with respect to water redox levels has been investigated. We conclude that Fe₂TiO₅ is a promising material comparable to hematite for constructing PEC cells
