Abstract: ZnO whiskers with a length of 30-40 mm and a diameter of about 1 mm were synthesized by co-precipitation of ZnSO₄ and Na₂CO₃ solution at room temperature followed by hydrothermal treatment of the as-prepared Zn₅(CO₃)₂(OH)₆ precursor at 160 ℃ for 6 h. The increase of the initial solution pH promotes the hydrothermal conversion of the particulate Zn₅(CO₃)₂(OH)₆ to ZnO whiskers. The presence of minor amount of EDTA in the hydrothermal solution promotes the one dimensional growth of ZnO whiskers, leading to the formation of ZnO whiskers with a length of 50-60 mm and a diameter of 1-2 mm.
