摘　　要：Rod-like ZnO particles were synthesized via a sol-gel method by adding ethylene diarnine （EDA） to the reaction system of Zn（Ac）2.2H2O and H2C2O4.2H2O. The crystal phase and morphology of the products were characterized by XRD （X-ray powder diffractometer） and TEM （transmission electron microscope） Rod-like ZnO belongs to the hexagonal Wurtzite system, with diameters and lengths of about 20-200 nm and 0.2-1.5μm, respectively. Experimental results showed that the morphology of nano-ZnO can be controlled by modulating the quantities of EDA added into the reaction system and that EDA plays ar important role in the formation of rod-like ZnO particles. The growth mechanism of the rod-like nano- ZnO was briefly discussed. The proposed facile, reproducible, effective and low-cost synthesis promises future large-scale preparation of nanostructured ZnO for application in nanotechnology.Rod-like ZnO particles were synthesized via a sol-gel method by adding ethylene diarnine （EDA） to the reaction system of Zn（Ac）2.2H2O and H2C2O4.2H2O.
