· JVASP-35249· Cu3O2

Cu₃O₂ is a mixed-valence copper oxide ceramic compound that combines copper in both +1 and +2 oxidation states, representing a non-stoichiometric intermediate phase in the Cu-O system. While not widely deployed in mature commercial applications, this material is primarily investigated in research contexts for semiconductor and photocatalytic properties, with potential relevance to optoelectronic devices, solar energy conversion, and gas-sensing systems where its intermediate bandgap and electronic structure offer advantages over conventional binary oxides like Cu₂O or CuO.
