Effect of Electric Field and Temperature in Electrochemical Dissolution and Deposition Process on Morphologies of ZnO Nanostructures

Abstract:

Zinc oxide nanostructures were synthesized by an electrochemical dissolution and deposition process. The zinc plates were immerged in deionized water and used as two electrodes. The process was operated by applying the electric field of 10, 12.5, 25 and 50 V/cm, the constant voltage of 10 V and varied the temperatures from room temperature to 70 °C during 1 h. It was found that the electric field and temperature of electrolyte solution had affected to morphologies of ZnO NSs and were grown in forms of nanoflakes, nanoparticles and nanorods.
