LaTiO2N

LaTiO₂N is an oxynitride semiconductor compound combining lanthanum, titanium, oxygen, and nitrogen in a perovskite-derived crystal structure. This is primarily a research material investigated for photocatalytic and photoelectrochemical applications due to its tunable bandgap that responds to visible light, positioning it as an alternative to traditional wide-bandgap semiconductors like TiO₂. While not yet widely commercialized, LaTiO₂N represents the broader family of metal oxynitrides developed for solar-driven catalysis, water splitting, and environmental remediation—applications where visible-light absorption and stability are critical advantages over conventional oxide photocatalysts.
