A three-way catalytic converter makes use of two catalysts to convert harmful gases to harmless gases. They are: 1  Reduction Catalyst and. 2  Oxidation Catalyst.he gases that finally come out of the catalyst chamber are N 2, CO 2, and H 2 O. 3-way catalytic converters are so named because they are capable of eliminating three pollutants â NO x, CO and HC.
Did you know? Catalytic converters can effectively remove hydrocarbons, carbon monoxide, and nitrous oxides from car exhaust. But they do not reduce harmful emissions of carbon dioxide (CO 2), which is a greenhouse gas that contributes significantly to global warming.However, catalytic converters are less efficient when used with diesel engines, which run colder than gasoline engines. Catalytic converters work best at higher temperatures.his is accomplished using a catalyst, which gives the device its name. The catalyst used in a catalytic converter is a combination of platinum (Pt), palladium (Pd), and rhodium (Rh). These metals coat a ceramic honeycomb (or ceramic beads) contained within a metal casing that is attached to the exhaust pipe.
