Selective Oxidation of Propane to Acetone over Au-(oxoTi) Catalysts

摘要

Supported Au catalysts catalyze selective oxidation of propane using a mixture of H2 and O2. The primary product changed from propene over Au/TiO2 to acetone over Au/TS-1. The fact that Ti exists as isolated species in TS-1 implies that the oxo-Ti-Au interface may be active in the selective oxidation reaction. We have investigated the catalytic properties of this interface by generating it in a controlled manner.
