In this Article, a green chemical synthetic route was developed to synthesize Te/C nanocables by using glucose as reducing agent and carbon source, Na2TeO3as a tellurium source, and surfactant cetyltrimethylammonium bromide (CTAB) as a structure-directing agent. The products are characterized in detail by multiform techniques: X-ray diffraction, energy-dispersive X-ray analysis, scanning electron microscopy, and transmission electron microscopy. The formation mechanisms of Te/C nanocables are tentatively proposed. By chemical etching of Te/C nanocables with different morphologies, various carbonaceous nanotubes can be obtained at room temperature. [ABSTRACT FROM AUTHOR]

Ag/C nanocables with cross-linked structure were obtained through the reduction of Ag +with glucose in the presence of sodium dodecyl sulfate (SDS) under hydrothermal conditions. In the process, glucose acts as reducing agent and carbon source, and the final morphology of the product was determined by the SDS concentration. The formation process of nanocables included two evolution stages: the synthesis of the Ag nanowires with cross-linked structure by the SDS assistant; the carbonization of glucose and the formation of an amorphous carbon layer on Ag nanowires surface.

MnO2nanostructures with sea urchin shapes have been prepared by an sodium dodecyl sulfate (SDS)-assisted hydrothermal treatment method. The products were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). XRD patterns indicated that the sea urchin shaped MnO2nanostructures were tetragonal phase. Furthermore, SEM and TEM revealed that MnO2nanostructures with sea urchin shapes consisted of MnO2nanorods 150−200 nm wide and several micrometers long. A growth mechanism of MnO2nanostructures with sea urchin shapes was suggested and explained in detail. [ABSTRACT FROM AUTHOR]
