Abstract
Chromium-doped mesoporous tungsten trioxide – with KIT-6 structure – was prepared through a chemical route. The resulting material was deposited on a micromechanically fabricated hot-plate and tested as a sensor for ammonia and trimethylamine in the temperature range of 200–500 °C. Maximum response was reached at 350 and 450 °C for ammonia and TMA, respectively. It was also found that the sensor shows a non-linear cross-sensitivity to the gases.
