It is shown that the effect of the catalytic layer is twofold: First it dramatically increases the sensitivity of the tungsten oxide film to benzene vapours and second, it de-sensitises the film to ethanol. The response of the sensors with catalytic filter to other gases such as CO, CH4, NH3 and NO2 has been studied. The results show that the use of two sensors (one coated with a catalytic filter and one uncoated) allows for the selective detection of benzene in the presence of any of these gases and ethanol"@en . .
