Abstract

The transformation of Et3SiH occurring with CSi bond breaking was studied on CabOSilsupported Cu, Ni, Rh, Pd, and Pt catalysts by the pulse technique in H2 and He at 473-673 K. A serious poisoning of the CSi bond breaking capability of the metals was observed. Cu proved to be much less sensitive to poisoning, and, contrary to the other metals, could be partially reactivated. The poisoning effect of the surface silicon residues was found to be different for the hydrogenation of propene, cyclohexene, and benzene and for the dehydrogenation of 2-propanol and cyclohexene. This new selective poisoning effect may be a new tool for modifying certain metal catalysts.
