Abstract
Evidence for the electronic interaction of CO2 with the SnO2 surface has been collected for the first time. The adsorption of CO2 at 100 °C resulted in an considerable increase in electric resistance of SnO2, holding a quantitative relation between them. Such interaction became invisible in the presence of H2O because of the interference.Keywords
