A Beginner''s Guide to NOx, NO and NO2 as Air Pollutants

20181213· While NO 2 is a primary pollutant, it is also a contributing component for secondary pollutants formed from a chemical reaction. The most common is ozone. Photochemical smog, most common in sunny, dry locations, is created when NO 2 from gas combustion is exposed to sunlight, splits and releases an oxygen ion (O). The released O combines with oxygen molecule (O 2) forming ozone …

Nitrogen oxide sensor Wikipedia

x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas). In a gasoline engine, NO is the most common form of NO x at around 93%, while NO 2 is around 5% and the rest is N 2 O. There are other forms of NO x such as N 2 O 4 (the dimer of NO 2), which only exists at lower temperatures, and N 2 O 5, for ...
