Novel one-dimensional (1D)/two-dimensional (2D) hybrids of sodium tungsten oxide@carbon nanocables anchored on reduced graphene oxide (rGO) nanosheets were successfully synthesized by a facile sonochemical method followed by annealing without extra carbon sources. Morphology, structure and chemical states of the hybrids were characterized by scanning electron microscopy, high resolution transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy techniques. The characterization results indicate that the nanocable structure is composed of single crystalline Na0.1WO3nanorod wrapped with thin graphitic carbon layer. Optical absorption peak of the hybrids demonstrates an evident red shift compared with physical mixture of sodium tungsten oxide/rGO, which indicates hybridization effect between the nanocables and the rGO nanosheets and promises potential of the hybrids for various nanodevice applications.
