Propylene epoxidation: High-throughput screening of supported metal catalysts combinatorially prepared by rapid sol-gel method
MetadataShow full item record
The gas phase oxidation of propylene using molecular oxygen was studied on a variety of supported metal catalysts. The most promising PO activity was obtained for Cu supported on high surface area SiO 2 and the multimetallic systems exhibit synergistic effects that increased the desired PO yield by several folds for Ag promoted with Cu on SiO 2 after screening a large number of catalysts by a high throughput testing technique. © 2009 Springer Science+Business Media, LLC.
