    Abstract: PROBLEM TO BE SOLVED: To provide a catalyst for epoxidizing olefins with an improved selectivity of olefin oxides, a method for preparing catalysts, and a method for preparing olefin oxides.SOLUTION: There is provided a catalyst for epoxidizing olefins comprising a carrier as well as silver, a rhenium promoter, a first co-promoter, and a second co-promoter that are deposited on the carrier, wherein a mole ratio of the first co-promoter to the second co-promoter is more than 1. The first co-promoter is selected from sulfur, phosphorus, boron, and mixtures thereof; and the second co-promoter is selected from tungsten, molybdenum, chromium, and mixtures thereof. A method for preparing the catalyst, and a method for preparing olefin oxides by reacting a feedstock including olefin and oxygen in the presence of catalysts are also provided. The present invention includes converting the olefin oxides into a 1,2-diol, a 1,2-diolether, a 1,2-carbonate, or an alkanolamine.
