Popis: Well-dispersed SnO 2 nanosheets were obtained by the reaction of SnCl 2 ·5H 2 O and CO(NH 2 ) 2 on Al 2 O 3 tube using homogeneous precipitation method. The morphology, size and phase of the nanosheets were analyzed by scanning electron microscope (SEM) and X-ray diffraction (XRD). A novel micro gas sensor based on as-prepared SnO 2 nanosheets was successfully fabricated. The gas-sensing results show that the sensor response of SnO 2 nanosheets sensor reaches 48.377 to 100 ppm ethanol with a response time less than 8 s.
