ZnO nanorods, ZnO thick nanosheets and ZnO thin nanosheets can be facilely synthesized at low temperature using Zn(CH3COO)2•2H2O, Zn(NO3)2•6H2O and ZnSO4•7H2O as zinc resources, respectively. In the novel synthesis process, the precursors were firstly prepared using the reaction of zincate and NaOH in ethanol/water mixed medium. Then ZnO nanorods and ZnO nanosheets can be obtained by calcined procuesors at 300°C. The method is simple and low cost and expected to be applied in industry in the future. In addition, the mixed medium could be recycled by distillation process. The kinds of zinc resources and reaction temperature have a noticeable effect on the morphology of the ZnO particles produced.
