· SrTaNO2

SrTaNO2 is an oxynitride semiconductor compound combining strontium, tantalum, nitrogen, and oxygen. This material belongs to the emerging class of mixed-anion semiconductors, which are primarily studied in research contexts for their tunable electronic and optical properties that differ from conventional oxides or nitrides alone. The material shows promise in photocatalysis, water splitting, and visible-light-driven energy conversion applications, where the nitrogen incorporation narrows the bandgap compared to traditional strontium tantalate oxides, making it potentially valuable for sustainable energy and environmental remediation technologies.
