Abstract: Silver based ethylene oxide catalysts having enhanced stability are disclosed. The enhanced stability silver based ethylene oxide catalysts include an alumina carrier which has been modified to include cavities on the surface of the carrier. The presence of the cavities on the surface of the modified carrier stops or at least impedes the motion of silver particles on the surface of the carrier during an epoxidation process. In particular, the cavities on the surface of the alumina carrier effectively trap and/or anchor silver particles and prevent them from further motion.
