SYNTHESIS OF DESIGNED TEMPLATES FOR NOVEL SEMICONDUCTOR MATERIALS WITH HOLLOW STRUCTURES

Abstract

We develop several strategies for the synthesis of novel templates based on a solution method aimed at the synthesis of hollow structures for functional materials. Hollow ZnO microrings are successfully established using a new sacrificial template route by employing insoluble salts as the template. We also develop an in situ template strategy to synthesize ZnO tubes on zinc foil in an acid medium to avoid the multiple steps that are currently used in the preparation of other hollow structures. Finally, a bubble template method is discovered for the preparation of a new type of complex ZnO hollow structures constructed by polyhedral particles. The unique methods presented herein provide a new template technique for chemically designing and synthesizing functional materials with hollow structures.
