- Ethanol gas sensing characteristics of semiconductor type gas sensors with channels composed of pure and (Mn, Co) co-doped ZnO nanoparticles were investigated in this study. The morphology and structure of ZnO nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). Compared with high temperature sintered ZnO nanoparticles, low temperature sintered ZnO nanoparticles have better sensibility. The main advantages of these sensors are featured in the excellent selectivity, fast and high response (sensitivity) to ethanol.
