Benzaldehyde hydrogenation over titania-covered Pt powder
- Pennsylvania State Univ., University Park, PA (United States). Dept. of Chemical Engineering
Titania when used as a support has been found to have a significant effect on the activity and selectivity of Pt during the hydrogenation of aldehydes and ketones. Turnover frequencies based on hydrogen adsorption sites are markedly enhanced, and rates per gram Pt (at similar dispersions) are also often increased. There are several explanations to account for this performance, at least partially. In an effort to determine the validity of these explanations, and hopefully to eliminate them as possibilities, a Pt powder was studied before and after the addition of varying amounts of TiO{sub 2} on its surface, and a physical mixture of this powder plus TiO{sub 2} was also examined and compared both to these catalysts and to Pt dispersed on TiO{sub 2}. The results follow.
