The catalytic coupling of CO 2 and propylene has been studied on a silica‐supported platinum–tin catalyst containing the well‐defined PtSn phase. Microcalorimetry of adsorption has been applied to investigate the interaction of the reactants with the surface of the catalyst. When the adsorption properties of the bimetallic catalyst are compared with those of monometallic counterparts, significant differences in the strength and number of adsorption sites concerning CO 2 and propylene are evidenced. The adsorption properties of the bimetallic catalyst have been related to its catalytic behaviour. Copyright © 2000 John Wiley & Sons, Ltd.
