以氯化锌和氢氧化钠为反应原料,利用水浴恒温加热,在溶液中直接制备出呈花状形貌的纳米ZnO;采用扫描电镜、X射线衍射、透射电子显微镜等分析方法对所得产物的形貌和结构进行了表征,结果表明,在低温(45℃)时可制备出大量呈花状形貌的纳米ZnO.

Flower-like zinc oxide (ZnO) nano-structures have been synthesized in the reaction of aqueous solution of zinc chloride and NaOH by water-bath heating method. The products are characterized by XRD, SEM and TEM. The results show that a large quantity of flower-like ZnO nano-structures can be obtained at 45℃.
