SnO2 nanorods were prepared by annealing precursor powders produced by mixi
ng three kinds of inverse microemulsions (I muE). The microstructures of th
e resultant nanorods were studied by means of X-ray diffraction (XRD), tran
smission electron microscopy (TEM) and selected area electron diffraction (
SAD). It has been found that the as-prepared materials have a rod-like shap
e with lengths of tens of micrometers and diameters of 30-200 nm under diff
erent conditions. We discussed the influences of temperature and surfactant
on the formation of SnO2 nanorods and the mechanism of the formation of Sn
O2 nanorods. (C) 2001 Published by Elsevier Science B.V.
