Answer
The reduction catalyst [Pt/Pd] of the catalytic converter separates the nitrogen atom from NO and NO2 molecules freeing oxygen in the form of O2 molecule.
2NO ⟶ N2 + O2
2NO2 ⟶ N2 + 2O2
Thus, the oxides of nitrogen which are pollutants are converted to free nitrogen by the catalytic converter thereby reducing pollution.
