The shift away from combustion-only car engines to hybrid cars results in much lower temperatures of the exhaust gasses, for which existing Platinum Group Metal (PGM) exhaust catalysts, such as the diesel oxidation catalyst (DOC), are not optimized. Umicore has recently developed new Pt-based catalysts promoted with post-transition metals, which are capable of lowering the CO oxidation temperature, even in the presence of other exhaust gasses such as hydrocarbons and water. The aim of this project is to gain understanding into the metal-promotor and metal-support interactions governing this reaction by developing and employing innovative in-situ and operando characterisation techniques based on X-ray, vibrational and luminescence spectroscopy, allowing the Pt-based catalyst to be tested under realistic DOC reaction conditions.
