“…A lot of interest is currently focused especially on catalysts for emission control in diesel engines, [2,5,12,13,14] since diesel engines enjoy increasing popularity: In the last decade, the quota of new registrations of passenger cars with diesel engines continuously increased in Germany from 14.6 % (1995) up to 44.8 % (first half of 2004). [3] Particularly diesel engines with their comparativeley cold lean-burn characteristics produce solid and liquid combustion products (besides gaseous compounds of course) which make the after-treatment in diesel automotive catalysts difficult, as will be shown below.…”

Scarcely any other technology is of such a global interest due to economical and ecological reasons like automotive catalysis, and world wide efforts are exerted to improve and optimize automotive emission control systems enclosing new engine concepts, better fuel quality, and novel exhaust catalysts. Especially the continuous improvement of the exhaust catalysts over the last 30 years brought major advances in saving ressources and fulfilling present and future emission directives. This paper deals with current developments in automotive exhaust catalysts. After an introductorily overview, the principles of spark ignition engines and diesel engines will be described, followed by selected fields of recent research of our and others groups. The focus is brought upon Pd‐only catalysts and new oxygen storage systems for three‐way catalysis, as well as on new concepts and characteristics of diesel oxidation catalysts based on platinum and palladium.

“…Especially, the exhaust from vehicles has become a troublesome problem. Although the three-way catalysts (TWCs) have been successfully developed to remove the CO, NO x and hydrocarbons in gasoline engine exhaust during the normal running period [1], these catalysts show very low efficiency for the oxidation of CO and hydrocarbons during the cold-start period because of the very low temperatures of the catalyst-bed and the exhaust itself (<200 • C), which results in the release of 60-80% of CO and hydrocarbons into the air [2]. Therefore, it is very necessary to explore novel oxidation catalysts for the removal of CO and hydrocarbons at relatively low temperatures.…”

“…in catalytic hydrogenations of aromatic molecules such as nitroaromatic compounds to anilines, the conversion of imines to amines, in reductive amination or alkylations, and many other processes [1][2][3]. Prominent applications of supported or unsupported platinum or of platinum alloys of different shapes and dispersity are gas/solid reactions such as the BMA process (synthesis of HCN from CH 4 and NH 3 ) [4], the oxidation of ammonia in the production of nitric acid [5], automotive exhaust gas purification systems [6][7][8][9], and, to a steadily growing extent, the use in fuel cell catalysts [10][11][12]. Especially in fuel cell catalysis very finely divided platinum particles are used on adequate support materials such as special grades of carbon black.…”
