A catalyst for gas phase oxidation of ethylene which excels in selectivity and life performance, a method for the production of the catalyst and a method for the production of ethylene oxide by the use of the catalyst are disclosed. Specifically, the catalyst for the production of ethylene oxide has silver deposited on a carrier containing 90.0-98.9 mass % of alpha-alumina, 0.01-1 mass % of a compound of at least one metal element selected from the group consisting of potassium and iron (calculated as oxide), 0.1-5 mass % of a silicon compound (calculated as oxide), and 1-5 mass % of zirconium compound (calculated as oxide) in inner portion thereof, the method for the production of this catalyst, and the method for the production of ethylene oxide by the use of this catalyst. |
