| Abstract | TiO₂ sol–gel films doped with gold nanoparticles are used as both optical and conductometric sensors for the detection of CO and H₂. Tests performed at 360°C show for the first time CO- and H₂-induced reversible variations in the optical absorption of thin TiO₂/Au sol–gel films. The absorbance changes are strongly dependent on both the testing wavelength and the film microstructure. Together with the sensing dynamics observed through an electric interface, it is possible to obtain a better understanding of the mechanisms involved in the detection of both gases. The presence of H₂ elicits almost ideal, step-like dynamic responses using conductometric detection. |
