Ce2 Cu1 N2 O2

Ce₂Cu₁N₂O₂ is an oxynitride ceramic compound containing cerium and copper, representing an experimental mixed-anion ceramic from the rare-earth oxynitride family. This material class is of primary research interest for advanced ceramic applications where the combination of metal cations with both oxygen and nitrogen anions can provide tuned electronic, optical, or catalytic properties distinct from conventional oxides or nitrides. While not yet established in mainstream engineering practice, rare-earth copper oxynitrides are being investigated for potential roles in photocatalysis, electronic ceramics, and other functional applications where the dual anionic framework offers compositional flexibility.
