Solution to Pollution:
Catalytic Converter:
Figure 4a:
Carbon
monoxide and oxides of nitrogen can be reduced by the use of catalytic
converter in vehicles.
Figure 4b:
The mesh of
ceramic or metallic foil made up of iron, chromium and aluminium increases the
surface are for the catalyzed conversion of oxides of nitrogen and carbon
monoxide to nitrogen and carbon dioxide. Rhodium, palladium, nickel, manganese,
and cerium can also be used as catalysts for this reaction.
