· O12 Na4 Ta4

O12Na4Ta4 is an inorganic sodium tantalate compound belonging to the mixed-metal oxide semiconductor family, characterized by a sodium-tantalum-oxygen stoichiometry. This material is primarily of research and developmental interest for photocatalytic and electrochemical applications, particularly in water splitting and environmental remediation, where tantalate-based semiconductors are valued for their chemical stability and band gap characteristics. The sodium component influences crystal structure and charge transport properties, making this compound potentially relevant for emerging energy conversion technologies, though industrial adoption remains limited compared to established tantalum oxide or perovskite alternatives.
