OMS were prepared from a layered manganese oxide (Na-Birnessite, Na4 Mni4027 9H20, 2 x oo) under hydrothermal reaction conditions with different pH values of the solutions. ... 

Inorganic molecular sieves in which all of the framework cations are coordinated octahedrally comprise a small but significant family of microporous solids. The octahedral molecular sieves, or OMS materials, related to manganese oxide minerals of the hollandite family, are the most important of these. Examples have been prepared by Suib and co-workers through the hydrothermal treatment of layered manganese oxides. Careful choice of additional metal ion content of such preparations controls the inorganic phase that forms. The... 

MnO has been also coated with PANl to improve its electrochemical performance. Shin et al found that the cobalt-intercalated layered manganese oxide (CLMO) displayed the excellent cyclability over 40 cycles, although it exhibited a low discharge capacity (143 mA h g at 40 mA g current density) [51]. After chemical oxidative polymerization of aniline... 

As the typical layered compound, MnO provides the open structure for conjugated-polymer intercalation [55]. The typical preparation methods for organic-intercalated MnO is complicated because of the fussy steps [55-59] (i) The layered manganese oxide (or Birnessite-type manganese oxide) A MnO (where A is K, Na, etc.) is first prepared by a soft...

Although there are numerous families of lamellar solids, only a handful of them exhibit the kind of versatile intercalation chemistry that forms the basis of this book. In arriving at the content of this volume, the editors have accurately identified six classes of versatile layered compounds that are at the forefront of materials intercalation chemistry, namely, smectite clays, zirconium phosphates and phos-phonates, layered double hydroxides (known informally as hydrotalcites or anionic clays ), layered manganese oxides, layered metal chalcogenides, and lamellar alkali silicates and silicic acids. Graphite and carbon nanotubes have not been included, in part because this specialty area of intercalation chemistry is limited to one or two molecular layers of comparatively small guest species that are capable of undergoing electron transfCT reactions with the host structure.
