Abstract

The present invention relates to a support for silver catalyst used in the ethylene oxide production, a preparation method for the same, a silver catalyst prepared from the same, and its use in the ethylene oxide production. The silver catalyst produced from the silver catalyst support has an improved activity, stability and/or selectivity in the production of ethylene oxide by epoxidation of ethylene.
