It is also used as an oxidizer in rockets and in motor racing to increase the power output of engines. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen.

Nitrous oxide, also known as laughing gas, is a colorless gas with a slightly sweet odor. It is commonly used in medical and dental procedures as an anesthetic, and it is also used as a propellant in whipped cream cans.
A catalytic converter is a device found in the exhaust system of vehicles that helps to reduce harmful emissions by converting them into less harmful substances. It contains a catalyst, typically made of platinum, palladium, or rhodium, that facilitates chemical reactions to break down pollutants.
Nitrous oxide is broken down by a catalytic converter through a process called reduction. The catalyst in the converter reacts with the nitrous oxide, causing it to split into nitrogen and oxygen molecules. These molecules are then released into the atmosphere, reducing the amount of nitrous oxide emissions.
Nitrous oxide is a greenhouse gas that contributes to global warming and climate change. It also plays a role in the formation of smog and acid rain, which can have negative impacts on human health and the environment. By breaking down nitrous oxide, catalytic converters help to reduce these harmful effects.
There are some potential downsides to breaking down nitrous oxide in automotive catalytic converters. The process requires high temperatures, which can increase fuel consumption and decrease engine performance. Additionally, some studies have suggested that the byproducts of the nitrous oxide reduction process, such as nitric oxide and nitrogen dioxide, may still be harmful to the environment.
