· Mo4 O8

Mo₄O₈ is a mixed-valence molybdenum oxide semiconductor compound, part of the broader family of substoichiometric molybdenum oxides (MoOₓ where x < 3). This material exists primarily in research contexts, where it is studied for its electronic properties and potential as a functional oxide in nanostructured and thin-film applications. Mo₄O₈ and related molybdenum oxides are investigated for use in catalysis, electrochemical devices, and optoelectronic components, where their tunable electronic structure and oxygen-deficient nature offer advantages over fully oxidized MoO₃ in redox-sensitive applications.
