Abstract
The effectiveness of using zeolites as a method of introducing variance in the gas responses of semiconductor metal oxide gas sensors is demonstrated. Screen printed tungsten trioxide (WO3) and chromium titanium oxide (CTO) thick films overlaid with the hydrogen form of different zeolites were exposed to organic vapours with similar functional groups. The composite metal oxide-zeolite gas sensors responses exhibit reproducible gas specific enhanced and diminished responses. (C) 2010 Published by Elsevier Ltd.
