Multilayered 1,2-ethylene-silica nanotubes were prepared with cetyltrimethylammonium bromide(CTAB)as a template and(S)-β-citronellol(CN)as a co-structure-directing agent.For a better understanding of the formation of this structure,the CN/CTAB molar ratio in the reaction mixtures was tuned.With increasing the CN/CTAB molar ratio,a hexagonal to lamellar phase trasformation was observed; and the morphologies of 1,2-ethylene-silica changed from rod to vesicle and then to tubular structure.CN droplets were proposed as the templates for the nanotubes.The obtained samples were characterized by means of X-ray diffraction,nitrogen sorption,field emission scanning electron microscopy and transmission electron microscopy.
