· NaCuO2

NaCuO2 is a layered sodium copper oxide ceramic compound that belongs to the class of mixed-valence transition metal oxides. This material exhibits interesting electrochemical and structural properties typical of copper oxide systems, making it a subject of research in energy storage and catalysis applications. While primarily investigated at the laboratory scale rather than widely deployed industrially, NaCuO2 and related sodium-copper oxide phases are of interest for battery cathode materials, heterogeneous catalysts, and functional ceramic applications where copper's variable oxidation states can be exploited.
