Abstract： By the method of chemical precipitation, zinc oxide powders were prepared with the precipitated precursors hydrothermal modified and unmodified by benzoic acid respectively. The effect of hydrothermal modification by benzoic acid on morphology of zinc oxide particles were characterized by XRD, SEM and other methods. The formation mechanism of zinc oxide nano-particles hydrothermal modified by benzoic acid was discussed. The results show that the zinc oxide particles obtained under the unmodified conditions are granular with average diameter of 300 to 400 nm. Through hydrothermal modifying precipitated precursors by benzoic acid, the zinc oxide nano-sheets can be prepared with thickness of 30 to 60 nm.
