The chemisorption of sulfur dioxide and chlorine on the surface of zinc oxide and the change in the electric conductivity of ZnO during the chemisorption process were studied. It was shown that both gases induce a negative charging of the surface of zinc oxide. The kinetics of the chemisorption of C12 and SO2 is described by the Zel'dovich-Roginskii equation.
The mutual influence of sulfur dioxide and chlorine during successive chemisorption was investigated. It was shown that the nature of the mutual influence depends on the temperature and the sequence of action of the gases. The results obtained were analyzed from the standpoint of the electronic theory of chemisorption on semiconductors.
