The catalyst used in the converter is mostly a precious metal such as platinum, palladium and rhodium. Platinum is used as a reduction catalyst and as an oxidation catalyst. Although platinum is a very active catalyst and widely used, it is very expensive and not suitable for all applications.
Although catalytic converters are most commonly applied to exhaust systems in automobiles, they are also used on electrical generators, forklifts, mining equipment, trucks, buses, locomotives and motorcycles. They are also used on some wood stoves to control emissions.n vehicles with OBD II, a second oxygen sensor is fitted after the catalytic converter to monitor the O 2 levels. The O 2 levels are monitored to see the efficiency of the burn process. The on-board computer makes comparisons between the readings of the two sensors.
