Abstract :
Room temperature operated recognition of gases and smells by UV activated SnO2 nanowires are demonstrated in this paper. The recognition and separation of CO, isopropanol, and benzene in concentrations down to 10 ppm in dry and humid air is shown. Also the smells of different burnt materials or fruit can be distinguished via linear discriminant analysis. The detection of the gases is possible within 10 s.
