Which device is commonly used to reduce nitrogen oxides emissions?

Catalytic converters are commonly used to reduce nitrogen oxides (NOx) emissions in vehicles and other internal combustion engines. These devices facilitate a chemical reaction that converts harmful gases produced during combustion into less harmful substances. Specifically, in the presence of a catalyst, nitrogen oxides are reduced to nitrogen and oxygen, which are naturally occurring and non-toxic components of the atmosphere.

Catalytic converters also play a crucial role in simultaneously reducing other pollutants, such as carbon monoxide and unburned hydrocarbons, further enhancing air quality. The effectiveness of catalytic converters is one reason for their ubiquitous use in automotive emissions control, reflecting their importance in environmental management strategies aimed at reducing vehicle emissions and improving air quality standards.
