B3 - In situ/operando Characterization of Noble Metal Clusters and Particles on Metal Oxides at Work

Objective

This project aims at tracking and correlating the structure and activity of oxide-supported metals under steady and transient reaction conditions. For this purpose, operando X-ray absorption/emission and IR spectroscopy complemented by in situ TEM will be applied to investigate selected catalysts based on Pt, Pd and Pt-Pd nanoparticles deposited on well-defined CeO₂, TiO₂, and Al₂O₃ supports under emission control reaction conditions. The complementary techniques will elucidate the impact of fluctuations in the gas feed and temperature on the sintering behavior, oxidation/reduction, redispersion processes, morphology changes of nanoparticles and segregation processes in bimetallic systems.
