Two-nozzle flame synthesis of Pt/Ba/Al2O3 for NOx storage

Büchel R., Strobel R., Pratsinis S.E., Baiker A., ETH Zürich, CH

A novel two-nozzle flame spray pyrolysis (FSP) process is presented for one-step preparation of Pt/Ba/Al2O3 particles for NOx storage-reduction (NSR) catalysts. These storage catalysts are of particular interest for mobile engines operating under lean conditions [...]

One-Step Flame-Synthesis of Carbon-Embedded and -Supported Platinum Clusters

Ernst F.O., Büchel R., Strobel R., Pratsinis S.E., ETH Zürich, CH

Carbon-embedded or -supported Pt-clusters were made by a scalable, single-step flame spray pyrolysis (FSP) process. Pt-containing precursors was dissolved in xylene and sprayed and combusted in a controlled oxidation atmosphere resulting in nanostructured, carbon-embedded Pt-clusters. [...]
