Nanostructured Catalysts

Solid catalysts are often structured on the nanoscale. Various methods are available to achieve such nanostructuring, including different templating pathways. The combination of high surface area support materials and pre-formed nanoparticles provides a highly flexible access to nanostructured catalysts. We use a wide range of different nanoparticles to synthesize high activity supported catalysts, for instance for ultra-low temperature CO oxidation. Elaborate procedures are used for the synthesis of core-shell systems, in which single metal nanoparticles are encapsulated in hollow spheres. Since the nanoparticles are effectively isolated from each other, sintering is effectively prevented.
