· Cu2 O4

Cu₂O₄ is an experimental copper oxide compound in the semiconductor family, composed of copper and oxygen in a 1:2 atomic ratio. While not widely established in commercial use, copper oxides of this stoichiometry are investigated for photocatalytic and photoelectrochemical applications due to their narrow bandgap characteristics and potential for light-driven reactions. Research into this composition focuses on environmental remediation, solar energy conversion, and catalytic processes where the copper-oxygen chemistry offers cost advantages over precious metal alternatives.
