Na1 Ni2 O3

Na₁Ni₂O₃ is a ternary oxide semiconductor composed of sodium, nickel, and oxygen, belonging to the family of mixed-metal oxides with potential electrochemical and catalytic properties. This material is primarily investigated in research contexts for energy storage applications (battery cathodes, supercapacitors) and as a catalyst precursor, where its layered or spinel-like structure can facilitate ion transport and surface reactivity. Its selection would be driven by the need for low-cost, earth-abundant transition metal alternatives to conventional lithium-based or precious-metal catalysts, though industrial adoption remains limited compared to well-established nickel oxide or sodium-ion battery chemistries.
