They convert nitrous oxides, unburnt fuel, and carbon monoxide to water, carbon dioxide and nitrogen.

To keep the car running - not at all. To minimize the amount of polluting exhaust - very.
A 1998 Cadillac Seville's catalytic converter typically contains about 0.1 to 0.2 grams of platinum. The exact amount can vary based on the specific design and model of the converter. In addition to platinum, these converters also contain palladium and rhodium, which are other precious metals used in catalytic converters for their catalytic properties.
The O2 sensors ( 2 of them ) nearest the engine are used to sense the amount of oxygen in the exhaust gasses and send a signal to the PCM that adjusts the air / fuel mixture for the engine . The O2 sensors ( 2 of them ) after the catalytic converters are called catalyst monitors and monitor how well the catalytic converters are performing
Cars that typically have the most rhodium in their catalytic converters are luxury and high-performance vehicles, particularly those with larger engines or those designed for high emissions standards. Brands such as BMW, Mercedes-Benz, and Audi often use more precious metals in their catalytic converters due to stricter regulations and performance requirements. Additionally, some hybrid vehicles may also contain higher amounts of rhodium to optimize emissions control. However, the exact amount can vary by model and year.
To reduce the amount of NOx, CO and HC that is expelled into the environment from a vehicle's exhaust. In other words, it helps keep the air we breathe a bit cleaner.
The oxygen sensors located before ( upstream ) of the catalytic converters are used to " sense " the amount of oxygen in the exhaust to adjust the air / fuel ratio for the engine
Catalytic converters reduce emissions of harmful pollutants that contribute to air pollution and smog, but they do not address greenhouse gases like carbon dioxide that contribute to global warming. Greenhouse gases are mainly produced by burning fossil fuels for energy, transportation, and industrial processes, and require broader strategies such as transitioning to renewable energy sources and improving energy efficiency to address.
As far as the environment is concerned, yes. Catalytic converters are very important in regulating the amount of pollution your vehicle emits. As far as vehicle performance, removing a catalytic converter could increase horsepower and exhaust flow. Removing the converter can (and does on most) cause the computer to over-correct for the improper oxygen sensor readings. This over-correction usually causes a reduction in power, economy, and running performance. It is also highly illegal.
its useful because it reduces the amount of harmful gases but it does not get rid of it completely. it reduses the amount of NOx, CO and HC that is released in the air
Seeing as this is in the car section....if this question is to see if its possible to extract the tiny amount of platinum from the ceramic lattice inside stolen catalytic converters, the answer is; you dont. Aside from destroying someone else's property by stealing the converter off their car, you will probably start a house fire trying to do it.
When it erupts, it releases a large amount of carbon dioxide into the atmosphere, polluting it.
