Synthesis and Growth Mechanism of Ultralong ZnO Nanocombs and Nanobelts on Cu Substrate

Abstract

We successfully synthesized ultralong ZnO nanocombs and nanobelts on Cu substrate for the first time. The morphology and structure of the as-grown ZnO nanocombs and nanobelts were characterized by means of scanning electron microscopy and X-ray diffraction. Scanning electron microscopy images show that Cu substrate is red and not oxidized, X-ray diffraction studies support Cu is present during the growth process, and we explained the growth mechanism for ultralong ZnO nanostructures.
