Abstract
Nanocrystalline TiO2 materials were prepared by a sol–gel method. A series of tests on indirect-heating sensors made of these materials showed that the nanocrystalline TiO2 materials exhibited high responses to TMA with anatase having higher response than rutile. It was also found that proper doping in nanocrystalline TiO2 could increase the TMA response, reduce its resistance, and enhance the selectivity against disturbing gases. The nanocrystalline materials doped with Ag+ showed the best performance among some other metal ions.
