Fabrication of Ag/C Coaxial Nanocables with Cross-Linked Structure by SDS-Assisted Hydrothermal Approach

Abstract

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.
