Abstract
Two methods of modification of monometallic platinum catalyst supported on functionalized active carbon were used for the preparation of Ge–Pt/C bimetallic catalysts: (i) conventional impregnation (CI) and (ii) controlled surface reactions (CSRs). All results, namely the study of germanium anchoring reaction, two test reactions (cyclohexane dehydrogenation and cyclopentane hydrogenolysis), H2 and CO chemisorption, indicate that the modification of Pt with Ge using CSRs was highly selective, i.e., almost 100% of Ge introduced was anchored to platinum. On the other hand results showed that in catalysts prepared by CI method Ge was located mainly on the support.
