Project Title: Lowering the operating temperature of catalysts for diesel particulat destruction
Project Description: Current technologies for controlling the emission of particulate from diesel vehicles rely on the reaction of NOx with the carbon content of the particles. However, the exhaust produced by passenger cars is often not hot enough, or does not contain enough NOx, to remove all the particulate. The aim of this project will be to improve the performance of known catalysts for the alternative (but slower) C+O2 reaction, allowing it to take place at typical car-exhaust temperatures. The major challenge will be to understand the mechanism by which gas-phase O2 is activated by the catalyst and transferred to the particulate, before the practical problem of ensuring effective contact between the catalyst and the immobilised particulate can be addressed.
