Preparation method of flower-shaped nanometer zinc oxide

The invention discloses a preparation method of flower-shaped nanometer zinc oxide and relates to a preparation method of nanometer zinc oxide. The preparation method aims at preparing the nanometer zinc oxide which is high in crystallinity and stability, large in specific surface area and free of clustering and has other characteristics. Rosin which is low in price and easy to obtain serves as surfactant to prepare the nanoscale zinc oxide. The method includes the following steps that an alcohol solution of rosin is added into a sodium hydroxide solution and is mixed evenly, and a zinc acetate solution is slowly added dropwise under the conditions of ice water bath and stirring; aging is performed at room temperature, then a hydrothermal reaction is performed, natural cooling and crystallizing are performed, suction filtration is performed, precipitate is washed, calcinating is performed after drying, and then the flower-shaped nanometer zinc oxide is obtained. The product obtained through the preparation me
