A new preparation of silver supported alumina catalysts, with highly dispersed and stable silver particles, is reported. The preparation, performed from a mixture of silver oxide and alumina, consists simply of heating this mixture under an oxidizing gas containing awater vapour concentration higher than 5.0 mol% in a temperature range between 903-948 K.
