· Ta4 Cu2 O12

Ta₄Cu₂O₁₂ is a mixed-metal oxide semiconductor combining tantalum and copper in a complex crystalline structure. This compound belongs to the family of transition-metal oxides and is primarily of research interest for electronic and photocatalytic applications rather than established commercial production. Its potential lies in photocatalysis, oxide electronics, and advanced functional materials where the combined properties of tantalum and copper oxides may offer advantages in light absorption, charge transport, or catalytic activity compared to binary oxide alternatives.
