Catalytic systems for neutralization of exhaust gases from diesel engines: modern challenges and technological solutions to improve a diesel oxidation catalyst

Diesel vehicles are responsible for the emission of not only soot and NОx to the environment, but also various organic and inorganic toxic compounds. The review provides a detailed discussion of the place of oxidation catalyst in the modern system for purification of exhaust gases from diesel engines, the ways to improve and optimize the oxidation catalysts intended for the neutralization of carbon monoxide and hydrocarbons according to the accepted standards, and the methods for decreasing the content of Pt group metals in the indicated catalytic systems.
