简介 The invention relates to a shell catalyst for producing vinyl acetate monomer (VAM). Said shell catalyst comprises an oxidic porous catalyst support in the form of a molded body that has an outer shell in which metallic Pd and Au are contained. The aim of the invention is to provide a shell catalyst for the production of VAM which has a relatively high activity and which can be produced at relatively low costs. According to the invention, the catalyst support is doped with at least one oxide of an element selected from the group consisting of Li, P, Ca, V, Cr, Mn, Fe, Sr, Nb, Ta, W, La and the rare earth metals.
