PROBLEM TO BE SOLVED: To provide a catalyst precursor for production of a catalyst used in ethylene oxide production which is excellent in activity, selectivity and economical efficiency.SOLUTION: A catalyst for ethylene oxide production is obtained by impregnating, with a solution containing a catalyst ingredient, a support which is a porous support of a specified specific surface area, a specified pore volume and a specified pore distribution especially containing more pores having diameters of 10 μm or larger and baking the resultant catalyst precursor. A method of producing ethylene oxide using the catalyst is also provided. |
