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.
我们报道了采用一种简单的低成本水热技术合成铁基钛酸盐（Fe₂TiO₅）薄膜。我们表明，由于具有有利的能带能量，这种Fe₂TiO₅作为光阳极用于光电化学水分解时表现良好。已对薄膜进行了进一步表征，包括相对于水氧化还原水平的能带位置。我们得出结论，Fe₂TiO₅是一种有前景的材料，可与赤铁矿相媲美用于构建光电化学电池。
