Sensitivity improvement of WO3 thick film to benzene using Pt catalytic filter
Original language description
We present the results on the use of a catalytic filter (Pt-Al2O3) printed on a tungsten oxide active layer to detect benzene selectively. It is shown that the effect of the catalytic layer is twofold: It dramatically increases the sensitivity of the tungsten oxide film to benzene vapours at first and on contrary it de-sensitises the film to ethanol. The response of the sensors with catalytic filter to other gases such as CO, and CH4 has been studied. The results show that the use of two sensors (one cooated with a catalytic filter and one uncoated) allows for the selective detection of benzene in the presence of any of these gases and ethanol.
