Disclosed is a propylene direct oxidation reaction catalyst capable of preparing a propylene oxide from propylene and oxygen at a higher yield than catalysts prepared by conventional methods, by applying a specific transition metal oxide promoter in preparation of a catalyst containing silver, a transition metal oxide promoter and a carrier through a slurry process. The present invention provides a propylene direct oxidation reaction catalyst, which is a supported silver catalyst used for preparing a propylene oxide from the propylene direct oxidation reaction, the catalyst including a molybdenum oxide and a tungsten oxide as a catalyst promoter.
A propylene direct oxidation reaction catalyst, which is a supported silver catalyst used for preparing a propylene oxide from a propylene direct oxidation reaction, the catalyst comprising, as a catalyst promoter, a molybdenum oxide (MoO3) and a tungsten oxide (WO3), wherein a carrier used for the supported silver catalyst is a zirconium oxide, and wherein the zirconium oxide has a monoclinic crystal phase fraction of 0.15-1.00 as calculated based on X-ray diffraction analysis results according to the following equation:
