· Mg2 Co4 O8

Mg₂Co₄O₈ is a ternary oxide semiconductor compound combining magnesium, cobalt, and oxygen in a fixed stoichiometric ratio. This material belongs to the spinel or spinel-derivative oxide family and is primarily investigated in research contexts for energy storage and catalytic applications. The compound's mixed-metal oxide structure makes it of interest for next-generation battery electrodes, electrocatalysts for water splitting, and potentially magnetic or optical devices, where the synergistic properties of cobalt and magnesium oxides can be exploited beyond what single-component oxides offer.
