Core-Shell PbI2@WS2 Inorganic Nanotubes from Capillary Wetting

摘要

One of the defining structural features of nanotubular structures is their long inner hollow cavity.Capillarity has been shown to drive the wetting and filling of multiwalled carbon nanotubes(MWNTs)with liquid and molten-phase inorganic salts if the.surface tension of the filling materials is less than about 180 mN m~(-1).It was subsequently shown,that various inorganic salts can be encapsulated inside the comparatively narrow(0.8-1.5 nm)hollow core of single-walled carbon nanotubes(SWNTs)by molten-phase capillary wetting.
