Abstract:
1. A method for making zinc oxide nano-structure, the method comprising the following steps of: (a) providing a growing substrate and a growing device, the growing device comprising a heating apparatus and a reacting room therein; (b) forming a metal layer on the growing substrate, the metal layer having a thickness capable of growing a plurality of zinc oxide nanotubes having open ends, and each of the plurality of zinc oxide nanotubes having a hollow center; (c) depositing a catalyst layer on the metal layer; (d) placing the growing substrate together with a zinc source material into the reacting room; (e) introducing an oxygen-containing gas into the reacting room; (f) heating the reacting room to a temperature in a range from 500° C. to 1100° C.; and (f1) growing a zinc oxide nano-structure comprising the plurality of zinc oxide nanotubes having open ends.
