✦ Synopsis

Catalytic and adsorption properties of (Pt + Fe) /Si02 catalysts prepared by coimpregnation of Si02 with FeC13 and H,PtCI, aqueous solutions have been studied. According to the X-ray diffraction data, Fe-Pt particles of the size 5-36 nm and bee or fee crystal lattice are formed during the reduction of catalysts by flowing hydrogen. Bimetallic catalysts exhibit higher specific activity for the reaction of CO hydrogenation than do monometallic samples. The enhanced activity of Fe-Pt particles manifests itself mainly through increased formation of C 4+ olefins. These observations suggest that the effect of Pt addition on the catalytic properties of silica-supported iron in CO hydrogenation is similar to the effect of potassium addition.
