Abstract

The activity and/or selectivity determining roles of carbonaceous deposits of various kinds and metal-metal oxide interfaces were studied in metal-catalyzed hydrogenation and isomerization reactions. Several probe molecules (cyclopropane, 1,1-dimethylcyclopropane, propylcyclobutane, methyloxirane, 2-methyl-2-butene, cyclohexene) were tested in the presence of H2 or D2, and the catalysts used were silica-supported Pt, Pd, Rh, Ni, and Cu. The properties of catalytic surfaces were characterized by IR spectroscopy and kinetic methods in static or flow reactors. To study the surface transformations during or after the reaction, six treatment or reaction types were applied. Carbonaceous deposits of different kinds were identified and their reaction influencing properties were analyzed. Metal-metal oxide interfaces were crucial in the hydrogenative ring opening of methyloxirane and the roles of the metal and the metal-oxide were elucidated.
