摘要: Abstract The SnO2 nanobelts were prepared through simply thermal evaporation process of metallic tin foil at 1100 °C under ambient atmospheric pressure without any catalysts. as-prepared products characterized using X-ray powder diffraction (XRD), scanning electron microscopy, energy-dispersive spectroscopy, transmission microscopy (TEM), and selected-area (SAED). XRD SAED results reveal that the are pure single-crystalline. widths range from 400 to 600 nm, thickness is about 50 nm. as-products high sensitivity fast response time ethanol gas.
