Abstract:
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.

Claim (Index 10):
The method of  claim 8 , wherein the silver precursor is at least one selected from the group consisting of silver oxide, silver nitrate, silver carbonate, silver acetate, silver oxalate, silver lactate, silver citrate and silver propionate.
