Abstract
The effect of traces of hydrogen sulphide and of sulphur dioxide on th e oxidation of methane over supported precious metals has been examine d. Both gases inhibited catalytic oxidation over Pd and Ph, apparently as a result of sulphate formation. However, the catalytic activity of platinum was slightly enhanced by the pollutants.
