Abstract
Abstract The catalytic treatment of motor vehicle exhaust gas has been a feature of all passenger cars in the USA since the 1975 model year. It has since been adopted in all the developed countries as the principal means of con-trolling the emissions from vehicles powered by Otto-cycle internal com-bustion engines. These include passenger cars, light trucks, and heavy-duty trucks. Catalysts have been developed for motorcycles and even smaller power plants. The so-called three-way catalyst (TWC) has been in use since the 1979 model year. The name reflects the simultaneous treatment by this catalyst of the two reducing pollutants, carbon monoxide and uncombusted hydrocarbons, and the oxidizing pollutant, oxides of nitrogen.
期刊介绍：
Catalysis Reviews is dedicated to fostering interdisciplinary perspectives in catalytic science and engineering, catering to a global audience of industrial and academic researchers. This journal serves as a bridge between the realms of heterogeneous, homogeneous, and bio-catalysis, providing a crucial and critical evaluation of the current state of catalytic science and engineering. Published topics encompass advances in technology and theory, engineering and chemical aspects of catalytic reactions, reactor design, computer models, analytical tools, and statistical evaluations.
