What do you know about how does the catalytic converter work?

For example: what it does to CO?

[Feman]

CO goes in and is converted to CO2... so you cant remove CO from the exhaust gasses as it would be in the form of CO2 after the redox reactions

If the CO is replaced by CO₂, and is no longer present, it is surely removed from the exhaust gases.
