Abstract
The present invention relates to hierarchical structured nanotubes, to a method for preparing the same and to an application for the same, wherein the nanotubes include a plurality of connecting nanotubes for constituting a three-dimensional multi-dendrite morphology; and the method includes the following steps: (A) providing a polymer template including a plurality of organic nanowires; (B) forming an inorganic layer on the surface of the organic nanowires in the polymer template; and (C) performing a heat treatment on the polymer template having the inorganic layer on the surface so that partial atoms of the organic nanowires enter the inorganic layer.
