Abstract

A cooperation of neighboring rhodium atoms in catalysis is prevented by the incorporation of tin atoms into the surface of an SiO2‐supported rhodium catalyst in accord with equation (a). This manifests itself for example in the absence (IR) of bridged CO ligands after chemisorption of CO on the Rh/Sn/SiO2 catalyst, and leads to an increase in selectivity in the hydrogenation of ethyl acetate: The amount of ethanol increases from 57.2 (Sn/Rh = 0/1) to 97.2% (Sn/Rh = 1.7/1). At the same time the conversion of ethyl acetate increases from 1.32 to 4.66%. (Figure Presented.)
