A novel highly sensitive and selective HS gas sensor at low temperatures based on SnO quantum dots-C nanohybrid: Experimental and theory study.

In this study, SnO quantum dots-fullerene (SnO QDs-C) nanohybrid as novel sensing material was synthesized by a simple hydrothermal method. The structure and morphology of the synthesized sample were studied by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The prepared hybrid was used as gas sensors for detection of different gasses including 70 ppm HS, 1% methane, and 1% propane at low temperatures of 100-200 °C.
