Zusammenfassung:	Provided are catalyst composites useful for the production of vinyl acetate monomer, as well as methods of making using same. The catalyst composites may comprise a support comprising silica and about 1 to about 3 wt-% alumina, wherein the support has a surface area of about 175 to about 300 m2/g; and an eggshell layer on the support comprising Pd and Au. L'invention concerne des composites catalyseurs utiles pour la fabrication de monomère d'acétate de vinyle, ainsi que des procédés de fabrication utilisant ces composites. Les composites de catalyseur peuvent comprendre un support comprenant de la silice et environ 1 à environ 3 % en poids d'alumine, le support ayant une surface spécifique d'environ 175 à environ 300 m²/g; et une couche de coquille d'oeuf sur le support comprenant Pd et Au.
