We successfully synthesized ultra-long 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 ultra-long ZnO nanostructures.
