What do catalytic converters do?

a catalytic converter is device made up from metals like metals like palladium and rhodium to reduce the toxic gases emitted in the environment

Explanation:

Catalytic converter is an exhaust emission controlling device. It was made to reduce pollutants in air. Almost every automobile has a catalytic converter. It is present to completely remove the fuel that was not combusted and other toxic/dangerous compounds before they are let out in the environment.

If the catalytic converters are not used then the harmful compounds are released in the air and thus increasing air pollution and also decreasing the air quality for breathing in the surrounding environment.

Catalytic inverter is a device that converts harmful gases into harmless gases

Example: Carbon monoxide is converted into carbon dioxide
