A novel hybrid nanostructure based on SiO2@carbon nanotube coaxial nanocable

Abstract

We present a simple, generally applicable procedure for obtaining diameter-controlled SiO₂@ carbon nanotubes (CNTs) coaxial nanocables. These coaxial nanocables with high solubility in polar solvents, have been used as functional templates for assembling CNTs/Au nanorods heterogeneous nanostructures to form multifunctional assembly system. These hybrid nanostructures may find applications in nanoelectronics, photonics, and nanodevices.
