Abstract

Abstract Synthesis of N-doped MgTiO3 with an ilmenite structure was examined as a new ilmenite-type oxynitride material. N-doped MgTiO3 with Sc-substitution was successfully obtained by flux-assisted nitridation using a LiCl-KCl eutectic under pure NH3 or 5% NH3. The oxynitrides gave visible light absorption which MgTiO3 did not show, and were active for sacrificial O2 evolution using AgNO3 under visible light irradiation.
