Facilitating ZnO nanostructure growths by making seeds for self-catalytic reactions Academic Article uri icon


  • Long and straight single-crystalline ZnO nanowires were successfully synthesized on ZnCl 2-coated Zn foils in oxygen environment by using simple thermal annealing processes. With relatively low reaction temperatures (410 and 700 C), nanowires whose lengths and diameters are up to 50 m and 10100 nm were obtained. We found that ZnO seeds created from ZnCl 2 played an important role in facilitating the ZnO nanowire growth via self-catalytic reactions. Systematic studies by altering critical synthesis factors that determine shape, length, diameter, and density of the nanowires were performed in order to unveil the growth mechanisms. We also compared the nanowires synthesized from Zn foils with tetrapod ZnO nanostructures synthesized from Zn powders at various temperatures. 2012 Elsevier Inc. 2012 Elsevier Inc.
