Abstract: The mixture of SnO2 powder and graphite was ground to ensure complete mixing, and was put into an alumina boat, then this boat was placed in the hot zone of the tube, heated from room temperature to 1100℃ and kept at this temperature for 2.5h in flowing argon. The X-ray diffraction analysis (XRD) indicates that the nanobelts are tetragonal rutile structure of SnO2. Scaning electron microscope(SEM) and transmission electron microscope(TEM) observations reveal that the nanobelts are uniform. The selected-area electron diffraction analysis(SAED) demonstrates that the nanobelts are single crystal . The SnO2 nanobelts might grow via a vapor-solid(VS) process.

Key words: tin dioxide, nanobelt, quasi-one dimensional nanostructure, vapor-solid(VS) process
