Summary on Grant Application Form |
One of the most exciting emergent branches of heterogeneous catalysis is that of environmental pollution control. However in the challenging field of automotive exhaust emission control, it is not widely appreciated that current diesel pollution control technologies cannot attain emission legislation designated for the year 2000. This proposal will focus on modelling the selective catalytic reduction of nitrogen oxides over Pt catalysts in the presence of known poisons and potential promoter species. In particular we hope to obtain molecule level insight into the complex interdependent interactions between catalyst components and develop predictive models for the rational design of new bimetallic dispersed catalysts. A detailed understanding of the mechanisms of catalyst poisoning and promotion in NOx reduction is currently lacking.This proposal aims to fund the construction of a combined UHV chamber/ high pressure reaction cell where a.) well-defined dispersed metal clusters may be prepared to create catalytically relevant model surfaces, and b.) these surfaces may be tested under realistic conditions of high temperature, pressure and space velocity. Novel organometallic surface chemistry will be utilised to synthesise Nox-traps in intimate contact with dispersed Pt clusters, and to form bimetallic particles of well defined surface alloy compositions.
