Description

Highlights: •Hydrothermal and solvothermal preparation of NaTaO3 heteroepitaxial films on SrTiO3(001) •Doping with Ba2+ cations up to 4 mol% relative to Ta •Feasibility of X-ray fluorescence holography for NaTaO3 film characterization -- Abstract: Perovskite-structured NaTaO3 films were epitaxially deposited on centimeter-sized SrTiO3(001) wafers by hydrothermal and solvothermal reactions to examine the surface science for an efficient photocatalytic water-splitting reaction. The addition of Ba cations in the starting solutions afforded Ba-doped NaTaO3 films. X-ray fluorescence holography was employed to investigate and confirm the heteroepitaxial relationship between the Ba-doped film and substrate.
