Abstract

Tin oxide (SnO₂) nanobelts were prepared by Horizontal Vapor Phase Growth™ (HVPG) technique without a catalyst. The surface morphology of the nanobelt was investigated by the High Resolution Scanning Electron Microscope (HRSEM) while the rutile crystal structure of the nanobelt was verified using X-ray Diffraction (XRD). The response of the SnO₂ nanobelt on ethanol was confirmed with an increase of electric current when exposed to ethanol.
