Time resolved Sintering Study of PdPt Alloy Nanoparticles Supported on Al2O3 During Methane Oxidation

With the end of production of conventional gasoline and diesel engines as legislated by the European Parliament, alternatives like biofuels and natural gas engines will become more important in coming years. However, methane is a greenhouse gas with a 20-times higher impact than CO2. Thus, it is vital to eliminate methane from exhaust gas for which PdPt alloy particles are most commonly used.
In our last experiment CH-6401 we observed severe sintering at the onset of methane production. With this experiment we plan to investigate this sintering process time resolved under reaction conditions for different alloy compositions and gas compositions. With the gathered information we will be able to supply collaborators within our special research project CRC 1441 with vital information for modelling sintering processes and reactivity in the complete parameter space of temperature, gas composition, and alloy composition.
