Abstract

The effects of surface oxidation of etched metallic Zn foils by hot water treatment for variable times and temperature investigated. ZnO nanostructures were obtained after undergoing hot water treatment at 50°C and 90°C for 2 to 24 hours. The SEM inorphology showed ZnO nanostar-like and nanoneedle-like were observed with different hot water treatment temperature. XRD analysis confirmed the existing of ZnO nanostar-like and nanoneedle-like in a hexagonal,wurzite structure. On the basis of the changes in morphology and microstructure induced h-y hot water treatment, it is concluded that the formation of ZnO are promising at low temperature.
