Abstract
A silver catalyst comprises a sinter resistant carrier covered with finely ivided particles of a metal, a metal alloy or a partially reduced metal oxide having silver deposited thereon such that the outer surface of the particles consists essentially of monometallic silver. The metals are selected from Re, Ru, Os, Rh, Ir, Pd, Pt, Pb and Bi; the metal of the alloy from Re, Ru, Os, Rh, Ir, Pd and Pt; and the oxide from tin dioxide, lead oxide and bismuth oxide. The catalyst is useful in a variety of applications, particularly in the preparation of ethylene oxide.
