TiO\u2082 sol\u2013gel films doped with gold nanoparticles are used as both optical and conductometric sensors for the detection of CO and H\u2082. Tests performed at 360\ub0C show for the first time CO- and H\u2082-induced reversible variations in the optical absorption of thin TiO\u2082/Au sol\u2013gel 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 H\u2082 elicits almost ideal, step-like dynamic responses using conductometric detection.Peer reviewed: YesNRC publication: Ye
