Catalytic monoliths with narrow particle size distribution in washcoats with well-defined gradients (C02)

• Subject Area: Solid State and Surface Chemistry, Material Synthesis ; Technical Chemistry
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426888090

This project aims at developing advanced washcoated monoliths as catalysts for studies under transient operating conditions, bridging the gap between model catalysts and more realistic reactor systems. The best candidates for both the supports (with defined morphology) and noble metal clusters/particles are used for the preparation of the washcoat of monoliths. This requires the scaling-up of promising nano-particle preparation routes with narrow size distribution, targeted washcoat preparation and zone and dual layer coating. The resulting coated monoliths serve as basis for X-ray microscopy, spatially resolved catalytic and structural studies and transient lab and engine bench tests.
