Abstract:

We have prepared a number of noble metal nanostructures from the organic medium that is constrained in the swollen liquid crystal templates. A suitable noble metal salt is either dissolved or phase transferred into toluene and this was used as the oil phase to swell the surfactant tubes that form the SLCs. The noble metal ions were then chemically and/or radiolytically reduced to form the nanostructures. Thus ultra thin Pd nanofilms, Pt nanorodes, Pt nanoballs and facetted Au nanoparticles were prepared and characterised.
