Abstract

SnOi, Ru/SnC2 and Pt/SnO2 were prepared by sol-gel condensation method. Ru/SnOa was also obtained by supporting the metal on SnU2 xerogel. The reactivity of these materials towards CO and ah-, studied by Electron Paramagnetic Resonance spectroscopy (EPR), suggests that the electron transfer processes at the oxide surface are favored by the presence of the metal, in the order Pt Ru ion-exchanged Ru-supported. A rationale was given for the differences and for the choice of a material suitable to high sensitivity gas sensors
