“…In a similar way, thiophene improves the selectivity towards unsaturated alcohols (S UOL ) for the monometallic ruthenium samples in the detriment of that of citronellal (S Cal ), this being more perceptible for sample Ru/KL-N. With respect to RuCu/KL-C, thiophene does not substantially modifies the reaction product distribution. This latter result is comparable to that found by Ashour et al [19] in the hydrogenation of crotonaldehyde in the gas phase over thiophene-modified Pd-Cu/SiO 2 catalysts.…”

Thiophene as Internal Promoter of Selectivity for the Liquid Phase Hydrogenation of Citral Over Ru/KL Catalysts

The effect of thiophene (Th) addition, in the concentration range 0-6 ppm, on the performance of Ru/KL catalysts is analyzed for the liquid phase hydrogenation of citral at 323 K and 4 MPa. The results show a promoter effect of thiophene on the overall hydrogenation activity of the catalysts, with a maximum at 3 ppm concentration of Th. Particularly, it is evidenced an increase in the selectivity towards the hydrogenation of the carbonyl group of citral.

“…IR spectra of CO on Pd/SiO 2 contain bands at 2085, 1984 and 1948 cm À1 , and similar IR spectra were also reported for Pd/SiO 2 catalysts [13,14]. The CO peak positioned at 2085 cm À1 (L 1 band) was assigned to CO linearly bound to steps or defects [15,16].…”

“…5 shows. Ashour et al studied co-adsorption of SO 2 and CO on Pd/SiO 2 ; they also reported that SO 2 preferentially bound on imperfect sites of Pd (B 1 site in this paper) to hinder CO adsorption [13]. Such bonding implies that the B 1 site corresponding to defect bridge sites of (1 1 1) facets possess higher potential energy, and so the site could readily bind with molecules during pre-adsorption.…”

“…Bimetallic catalysts with group 10 metals, Ni, Pd, Pt. Several bimetallic catalysts having metal from group 10 have been investigated in chemoselective hydrogenations, like Pd-Cu/SiO 2 [81,104], Pd-Sn/SiO 2 [105,106], Ni-Cu/ SiO 2 [102], Ni-Co-B [125], Ni-Pt/Y [24], Pt-Sn/Al 2 O 3 [43,64,127], Pt-Sn/SiO 2 [29], Pt-W/Al 2 O 3 [116], Pt-Ge/ Al 2 O 3 [43,127], Pt-Sn/C [43,126], Pt-Co/SiO 2 [128], Pt/ ZnO [36,67], Pt-Sn-B [108], Pt/SnO 2 [68,69], Pt-Sn/SiO 2 [29,[129][130][131][132], Pt-Sn/MgO [15], Sn/Pt(1 1 1) model catalyst [107] and Pd-Au/C [133].…”
