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.
