· JVASP-29862· Mo2H2O7

Mo₂H₂O₇ is an experimental molybdenum oxide hydrate ceramic compound belonging to the mixed-valence transition metal oxide family. This research-phase material is of primary interest in electrochemistry and catalysis applications, where layered molybdenum oxides show promise for energy storage and chemical conversion processes. The hydrated oxide structure makes it potentially suitable for applications requiring ionic transport or surface-active catalytic sites, though it remains largely a laboratory compound without established commercial production or widespread industrial deployment.
