摘　　要： ZnO nanorods were successfully synthesized by thermal decomposition of Zn（OH）2 in the ionic （liquid） 1-butyl-3-ethylimidazolium tetrafluoroborate, and the growth mechanism of ZnO micro-crystallites was presumed. Their structure and morphology were characterized by means of transmission electron microscopy（TEM）, infrared spectroscopy（IR）, and X-ray powder diffraction（XRD）. The TEM results （indicate） that the diameters and lengths of the ZnO nanorods were ca. 25 nm and ca. 150 nm, respectively. The IR spectra show that the ZnO nanorods were modified by 1-butyl-3-ethylimidazolium tetrafluoroborate. The XRD pattern reveals that the prepared ZnO nanorods belong to the hexagonal crystal system. The above-mentioned results indicate that ionic liquid can not only act as a reaction medium but also modify ZnO nanorods in the reaction.
