catalytic reduction of nitrogen oxides

What is a Three-Way Catalytic Converter?

A Three-Way Catalytic Converter (TWC) is used in gasoline engines to reduce NOx, carbon monoxide (CO), and unburned hydrocarbons (HC) simultaneously. The catalyst is typically made of platinum, palladium, and rhodium. The key reactions in TWC are:
2NO → N2 + O2
2CO + O2 → 2CO2
2CxHy + (x+y/4)O2 → xCO2 + y/2H2O
