1. A process for preparing a supported silver catalyst for the production of alkylene oxide by the vapor phase oxidation of alkene with an oxygen containing gas comprising:

  • contacting a silver-containing catalyst support with a solution comprising a solvent and at least one metal-containng promoter other than alkali metals or alkaline earth metals at conditions sufficient to associate the desired amount of said metal-containing promoter with said silver-containing catalyst support to enhance the performance of said supported silver catalyst, wherein said solvent does not coordination couple with said metal-containing promoter and said metal-containing promoter in said solution has an increased affinity to said silver-containing catalyst support relative to the affinity of said metal-containing promoter in a similar solution to a similar catalyst support without silver.
