"Pattern formation during the CO oxidation reaction on non reconstructing platinum group metal"
Sunday, 21 October 2007
Next Tuesday professor Stefan Wehner from University of Bayreuth (Germany) will give a seminar on pattern formation. I attach below a summary of the talk. The seminar will take place in the laboratory of Matter out of Equilibrium (DFI, downstairs) at 16pm.
Best, Enrique.
Abstract
The catalytic CO oxidation on platinum metal surfaces attracts high interest not only from the scientific point of view but also as a result of industrial needs. Some hundred million cars use a three way catalytic converter to clean their exhaust. One task of this exhaust cleaning process is the removal of carbon monoxide via oxidation to CO2. The CO oxidation on platinum metal catalysts has been repeatedly examined over the decades using various surface science techniques. The (111)-surfaces of Platinum, Palladium, Rhodium and Iridium do not reconstruct under reaction conditions and have been therefore selected for the ongoing studies.
