Using Surface Chemistry to Probe the Mechanisms of Emissions Aftertreatment Catalysts

Lead Research Organisation: Cardiff University
Department Name: Chemistry

Abstract

The control of exhaust emissions from vehicles with internal combustion engines is of vital importance. In particular, the emissions of carbon monoxide, volatile organic compounds, nitrogen oxides and particulates have to be controlled, and ideally eliminated totally. Catalysis has a critical role in controlling vehicle emissions, and currently catalytic technology is employed on gasoline and diesel fuelled vehicles. Although the catalysts employed are efficient the permitted emission levels of pollutants are continually being reviewed, and ever stricter emission targets are regularly introduced. In order to meet these targets improvements in engine combustion technology are important, however, in parallel improvements in catalyst performance are also required.

This project is in collaboration with Jaguar Land Rover, and it will focus on enhancing fundamental understanding of catalysts used for vehicle exhaust after-treatment. A range of model catalysts will be studied for reactions leading to removal of carbon monoxide, hydrocarbons and nitrogen oxides. Particular focus will be on establishing robust relationships between the microstructure of the catalytically active components and catalyst performance. This fundamental understanding will aid the rational design of the next generation of emission control catalysts.
