• The work function of silver oxide (Ag<SUB>2</SUB>O) decreased by as much as 0.8 eV on exposure to 2-propanethiol [(CH<SUB>3</SUB>)<SUB>2</SUB>CHSH]. The change in work function was irreversible at room temperature, and proportional to the amount of thiol in case where the partial pressure is low, but reversible at 200 °C. The conductivity of the Ag<SUB>2</SUB>O disk showed no substantial change by exposure to thiol. From the infrared absorption spectral studies, it was found that the thiol reacted with the silver oxide forming a (CH<SUB>3</SUB>)<SUB>2</SUB>CH–S–Ag group on the surface. The relationship between the work function and the chemical processes occurirng at the solid surface is discussed.
