In this work, we study the influence of the introduction method of Pt atoms on the sensitivity to traces of ethanol of Pt-doped SnO 2 sensors. The tin oxide films were obtained by a screen-printing process. Two different methods were employed to introduce Pt atoms on SnO 2 films. In the first one, the Pt atoms were added to the screen-printed tin oxide layer by using RF magnetron sputtering...
