The synthesis of ZnO prickly spheres using precipitation followed by heating treatment was investigated. Zn(OH)₂ precursor was prepared by precipitation process using Zn(CH₃COO·₂·2H₂O in mixed 1-propanol-water solvent. Sodium dodecyl sulfate (SDS) as the anionic surfactant was added to control the morphology. The size and structure of ZnO prickly spheres were studied using XRD, TEM and SEM. The results showed that the morphologies and size of the spheres strongly depended on the volume ratio of 1-propanol/water and molar ratio of SDS/Zn²⁺. ZnO prickly spheres composed of nanorods could be obtained, when the volume ratio of 1-propanol/water=2:3 and the molar ratio of Zn²⁺/SDS≈450:1.
