How Do Different Gases in the Atmosphere Interact with Catalysts?
The presence of specific gases such as oxygen, hydrogen, and nitrogen oxides can have profound effects on catalytic reactions. For instance, in automotive catalytic converters, oxygen is crucial for the oxidation of carbon monoxide and unburned hydrocarbons. Conversely, certain gases like sulfur compounds can poison catalysts, reducing their effectiveness by binding strongly to active sites and blocking reactant access.
