B1 – Synthesis and Characterization of Metal Oxide Supports with Anisotropic Shape

Objective

Project B1 aims at the synthesis and characterization of metal oxide supports (CeO2, Al2O3, TiO2) with anisotropic shape. This includes materials with well-faceted crystal surfaces (e.g. tetrahedra, octahedra, cubes) and those with high surface area (nanoplates, nanorods, nanotubes, hollow nanospheres) as well as the thermal, structural and chemical stability of composite catalysts (i.e. metal oxide support with deposited Pt/Pd) under transient conditions. Electron microscopy and electron spectroscopy (e.g. electron energy loss spectroscopy, tomography, pair-distribution analysis) will be used to characterize the 2D/3D morphology, the local oxidation state and the metal-support interaction.
