· Cu1 Ni3 O4

Cu1Ni3O4 is a mixed-valence copper-nickel oxide ceramic compound belonging to the spinel family of semiconductors. This material exhibits interesting electrochemical and catalytic properties due to its mixed metal oxidation states, making it an active research compound rather than an established commercial material. It is primarily investigated for energy storage and conversion applications, particularly in electrochemical catalysis, battery electrodes, and supercapacitor systems, where its semiconductor behavior and redox activity offer potential advantages over single-metal oxides.
