Pt crystallite size effects on ..delta..H/sub ad/ were investigated by varying particle sizes from 1.5 to 1500 nm on SiO/sub 2/. This property for CO and H/sub 2/ adsorption on Pt is much less affected by crystallite size than on Pd. We have completed our study of heats of adsorption on Pd. It also has provided insight into the H/sub 2/-D/sub 2/ exchange reaction on Pd. The study of C/sub 6/H/sub 6/ hydrogenation over Pd catalysts has been completed. We have found that the rate of acetone hydrogenation to isopropanol can be enhanced 100- to 1000-fold over TiO/sub 2/-supported Pt. Ongoing studies of crotonaldehyde hydrogenation have provided evidence that selective hydrogenation of the C=0 bond compared to the C=C bond can be induced by a metal-support effect. Only butyraldehyde is obtained over Pt on typical supports like SiO/sub 2/ and Al/sub 2/O/sub 3/ whereas the use of TiO/sub 2/ can produce over 35% crotyl alcohol.
