The adsorption of NO on SnO2 has been studied in the temperature range from 0 to 86°C, at pressures from 0.4 to 3.5 Torr. The adsorption isotherms are described by the Freundlich equation. The rate of adsorption obeys the Roginskii-Zeldovitch equation and decreases with increasing temperature. The reduction of SnO2 with carbon monoxide results in a drop in the adsorption rate and in the amount of adsorbed NO.
