Multiwall WS2 nanotube templates were used as hosts to prepare core-shell Pbl2@WS2 nanotubes by a capillarywetting method. Conformal growth of Pbl2 layers on the inner wall of the relatively wide WS2 nanotubes (i.d. ca.10 nm) leads to nanotubular structures which were not previously observed in narrow carbon nanotube templates. Image simulation after structural modeling (see picture) showed good agreement with the experimental HRTEM image.
