· JVASP-54698· Mn2HO4

Mn₂HO₄ is a manganese oxide hydroxide ceramic compound belonging to the family of mixed-valence manganese oxides. This material is primarily of research interest for electrochemical energy storage and catalytic applications, where manganese-based ceramics are valued for their variable oxidation states and ion-exchange capabilities. It is notable in battery cathode development and heterogeneous catalysis as a potentially cost-effective and earth-abundant alternative to precious-metal or cobalt-based systems.
