High quality ZnO nanocombs have been fabricated in high yields through oxidative evaporation of pure zinc powder without catalyst at 600–650 C. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations showed that the resulting ZnO nanostructures have one main type of single crystal morphology. Investigations through XRD revealed that the growth of the synthesized ZnO nanostructures was controlled ... إقراء المزيد
