The effect of the support, SiO 2 or Al 2 O 3, on the promotion of platinum by Cr–ZnO in the selective hydrogenation of cinnamaldehyde has been studied. Cr–ZnO could be well dispersed on the SiO 2 support, forming small particles as revealed by TEM, XRD and XPS. However, the same results could not be obtained when the support used was alumina.Cited by: 20

1. Introduction. Aluminum oxide is widely used as a support for various catalysts, mostly in the form of γ-Al 2 O 3.According to Morterra and Magnacca , this is due to a number of factors.First, the alumina surface has Lewis acid sites, which have a major effect on the distribution and state of the active components and catalytic activity in different reactions.Cited by: 276

XRD and IR measurements indicated that the support in the Co-Al2O3 catalyst underwent partial nitridation forming aluminum nitride and nitrogen containing Co species due to the SEA synthesis conditions. It was found that the Co-Al2O3 catalyst, under identical reaction conditions, could achieve similar ethanol conversion and ethylene selectivity ...Author: Priya D.

Pt/Al 2 O 3 with 0.1 wt% Pt could completely convert toluene (1000 ppm, SV=24000 mL·g −1 ·h −1) to CO 2 at about 180 ℃.. TOF value calculated with the dispersion of Pt can reach 0.0685 s −1, representing a high utilization efficiency of Pt.. The reaction obeys the modified L-H mechanism and synergism of Pt nanoparticles and Al 2 O 3 support enhances the activity.Cited by: 2
