摘要：

The reaction of sub-ppm amounts of SO2 and NO2 in dry and humid air on a gold foil was studied using a chemical reactor technique. Initially a humidity-independent transient reaction occurs that produces NO and SO3. This reaction is inhibited by the sulfuric acid formed. After this stage another reaction follows that is strongly humidity-dependent and occurs on the gold surface beneath a film of aqueous sulfuric acid. This reaction produces HNO2, NO, and H2SO4.
