· Sr0.5TaO3

Sr0.5TaO3 is a perovskite-structured oxide semiconductor containing strontium and tantalum, representing a mixed-valence transition metal oxide compound. This material is primarily investigated in research contexts for photocatalytic and photoelectrochemical applications, particularly water splitting and environmental remediation, where its band gap and electronic structure offer potential advantages over conventional titanium dioxide-based catalysts. The strontium doping strategy is employed to modify electronic properties and enhance light absorption compared to undoped tantalum oxide phases, making it relevant to emerging clean energy and catalysis technology development.
