This study was undertaken to evaluate the potential importance of gas-solid interactions in polluted atmospheres. Model calculations that employed collision theory, transition state theory, and data from the catalysis literature were used to determine the conditions under which the heterogeneous processes could compete with homogeneous gas phase reactions known to be important. Laboratory experiments were conducted with simulated atmospheres to determine whether or not the theoretically derived criteria could be met under ambient conditions. Among the gases studied were NO2, NO, O3, CO. The selection of the solids used in these studies was based on their abundance in polluted atmospheres, as well as on their known catalytic activity. Evaluation of the experimental results leads us to conclude that heterogeneous decomposition of NO2 and O3, as well as heterogeneous oxidation of CO, can be important atmospheric processes. Results from experiments conducted in the presence of moisture indicate that water does not poison catalytic activity. It was found that heterogeneous processes that involve NO are not likely to compete with gas phase reactions.
