Synthesis and Electrochemical Property of Bi2Se3 Nanotubes with Laminar Surface
Abstract:A novel hydrothermal method has been developed for the preparation of Bi2Se3 nanotubes with the laminar surface. The method is based on the template-engaged synthesis in which the as-prepared Se nanotubes were used as template reagent. The morphology, constitution and crystalline phase of the products as-obtained were characterized by SEM, XRD and XPS. On the basis of a series of experiments and characterizations, the effect factors (such as the reaction temperature and the atom ratio of Bi and Se in the precursors) and the formation mechanism of the Bi2Se3 nanotubes were discussed. Furthermore, the electrochemical property of the Bi2Se3 nanotubes was determined by the voltammetric technique, and the significant results were obtained.
