Intercalation Reactions of Layered Manganese(III, IV) Oxides

Abstract Layered hydrated birnessite-type manganese oxides have been intercalated with n-alkylammonium ions by ion-exchange for interlayer sodium or potassium, and by acid-base reactions. The expanded phases have modified interlayer environments and can be used as precursors for intercalation of aniline, which is oxidised and polymerised between the layers.
