Abstract

original image

The right mix! Significant synergistic effects exist between RuOx and CuOx for the propylene epoxidation by oxygen. While supported CuOx and RuOx alone both catalyzed the formation of acrolein as the main partial oxidation product, the combination of RuOx and CuOx in an appropriate ratio afforded an efficient and stable epoxidation catalyst. The supported nanocomposites with the direct contact interface between CuOx and RuOx were proposed for propylene oxide formation (see figure).
