The Microwave-Assisted Synthesis and Gas Sensing Properties for Ethanol of SnO2 Nanomaterials
With the advantages of the microwave-assisted method, good crystalline quality SnO2 nanomaterials were successfully synthesized. The morphology and microstructure of SnO2 were characterized by X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy and high-resolution (HRTEM) used to examine SnO2 nanomaterials. Indirect-heating sensors based on nanorods were fabricated and investigated for the gas sensing properties to ethanol. The investigation demonstrates that the sensor based on prepared SnO2 nanomaterials has good sensitivity, low detection limit and short response and reversion time to ethanol at 275 °C.
