- Abstract
- The Sb-doped SnO2 nanowire network sensors were prepared by thermal evaporation of the mixtures between tin and antimony powders. Pure SnO2 nanowire networks showed high sensor resistance in air (99 M ), similar gas responses to 4 diffferent gases (5 ppm C2H5OH, CO, H2, and trimethylamine), and very sluggish recovery speed (90% recovery time > 800 s). In contrast, 2 wt% Sb-doped SnO2 showed the selective detection toward C2H5OH and trimethylamine, relatively low resistance (176 k ) for facile measurement, and ultrafast recovery speed (90% recovery times: 6 -18 s). The change of gas sensing charactersitics by Sb doping was discussed in relation to gas sensing mechanism.
