Abstract
Tin dioxide (SnO2) nanobelts have been successfully synthesizedin bulk quantity by the CVD process based on the thermal evaporation oftin powders. The x-ray diffraction analysis indicates that thenanobelts are the tetragonal rutile structure of SnO2. Scanningelectron microscopy and transmission electron microscopy observationsreveal that the nanobelts are uniform. The selected-area electrondiffraction analysis demonstrates that the nanobelts are singlecrystals. The energy dispersive x-ray analysis of the nanobelt showsthat the nanobelts are composed of Sn and O. Gas-sensing componentshave been manufactured with prepared SnO2 nanobelts. Theirperformance indicates that SnO2 nanobelts have high sensitivityand selectivity to liquefied petroleum gas with fairly goodresponse-recovery characteristic and stability at 220°C.
