ceramic

· JVASP-102837· MnH2O2

MnH2O2 is an experimental ceramic compound containing manganese, hydrogen, and oxygen—a mixed-valence oxide-hydride material that belongs to the broader family of layered metal hydroxides and oxyhydroxides. This compound is primarily of research interest for energy storage and catalytic applications, where the combination of manganese redox chemistry and tunable layer spacing makes it a candidate for electrochemical devices. Its potential relevance lies in emerging technologies such as supercapacitors, battery electrodes, and heterogeneous catalysis, where structural flexibility and surface reactivity are valued over conventional oxides.
