2 S-F/Pd(II) hybrids on the hydrogenation of 1-octene in methanol as a catalytic test were evaluated. 100 % conversion to n-octane at T = 323.1 K and P = 15 bar, was obtained with both catalysts and most of Pd(II) was reduced to Pd(0) nanoparticles, which remained on the AC surface. Reusing of the catalysts in three additional cycles reveals that the catalyst bearing the F ligand with larger Pd-complexing ability showed no loss of activity (100 % conversion to n-octane) which is assigned to its larger structural stability. The catalyst with the weaker F ligand underwent progressive loss of activity (from 100 % to 79 % in four cycles), due to the constant aggregation of the Pd (0) nanoparticles. Milder conditions, T = 303.1 K and P =1.5 bar, prevent the aggregation of the Pd(0) nanoparticles in this catalyst allowing the retaining of high catalytic efficiency (100 % conversion) in four reaction cycles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
