· CuTaO3

CuTaO3 is a ternary oxide ceramic compound combining copper and tantalum in an oxide matrix, belonging to the broader family of complex metal oxides with potential semiconductor properties. This material remains primarily in the research and development phase, investigated for optoelectronic and photocatalytic applications where its unique electronic structure and phase stability could offer advantages over binary oxides. Interest in CuTaO3 stems from its potential use in visible-light photocatalysis, thin-film electronics, and energy conversion devices, where the combination of copper and tantalum oxides may enable band gap engineering and enhanced catalytic activity compared to single-component alternatives.
