在聚氧乙烯五醚（NP5）,聚氧乙烯九醚（NP9）,乳化剂（OP）和环己烷组成的微乳体系中制备二氧化锡前驱物.然后再经800～820℃焙烧2.5h,成功地制备了直径为30～90nm,长5～10μm的金红石结构的二氧化锡纳米棒,并用透射电子显微镜,电子衍射,X射线衍射对二氧化锡纳米棒的结构进行了表征.用熔盐合成机理对其形成进行了讨论,初步认为是成核、长大过程形成了二氧化锡纳米棒.
SnO2 nanorods with the rutile structure were prepared by annealing precursor powders?， which were produced by mixing three kinds of microemulsions (NP5，NP9, OP and
cyclohexane with the volume ratio 1:1:1:2) in the presence of salts such as SnCl4，Na2CO3, NaCl respectively. The structure and morphology of SnO2 nanorods
were investigated by transmission electron microscopy (TEM), selected area electron diffraction (SAED) and X-ray diffraction. The results showed that the diameter
and length of the as-prepared nanorods were 30～90nm and several micrometers respectively. The nanorods were perfect crystals. The mechanism of the formation
of SnO2 nanorod was simply discussed in terms of the nucleation and growth process.
