The surface sites of Cd and Sn with different coordination were characterized by chemisorption of CO. It was found, differing from the case in well-oxidized S n 0 2, that electrical conductance of Sn.WO,, and Cd^S films appeared to either increase or decrease when exposed to CO depended on concentration of surface Sn and Cd ions, partial pressure of analyzed gas and operating temperature.ena-SnxWOyIR-spectroscopyCdxSchemical compositionArticle
