A Novel Preparation Method of Ni–Sn Alloy Catalysts Supported on Aluminium Hydroxide: Application to Chemoselective Hydrogenation of Unsaturated Carbonyl Compounds

Abstract

A novel method was applied for the preparation of Ni–Sn alloy catalysts that were utilized for chemoselective hydrogenation of unsaturated carbonyl compounds, producing unsaturated alcohols almost exclusively. The formation of the Ni–Sn alloy may have played a key role in the enhancement of the chemoselectivity.

Total Hydrogenation of Biomass-Derived Furfural Over Raney Nickel-Clay Nanocomposite Catalysts

“…The yield of THFalc gradually increased while the yield of FFalc gradually decreased as temperature was increased, and complete formation of THFalc (~99%) was achieved at 393 K. It is clearly observed that at 333-343 K, the yield of FFalc (72%) higher than that of THFalc (24%) indicating hydrogenation of C=O bond is favorable rather than C=C bond. These results are consistent to our previous results on the chemoselective hydrogenation of furfural over Ni-Sn alloy catalysts [27][28].…”

Selective Hydrogenation of Dodecanoic Acid to Dodecane-1-ol Catalyzed by Supported Bimetallic Ni-Sn Alloy

“…The H2 uptake supported Ni-Sn alloy in this work was much lower than that of the Raney Ni or supported Ni on aluminium hydroxide, suggesting that the presence of second metal of Sn reduced significantly the accessibility of hydrogen on the surface of Ni metal. Consequently, the catalytic reaction may be effectively proceeded at high pressure of H2 as its have been reported previously [15][16][17][18][19],…”

“…NiCl2 or NiCl24H2O) produced from both bulk and supported Ni-Sn alloys [15] and, second, from Raney Ni-supported on aluminium hydroxide (R-Ni/AlOH), which produced a nickel-tin alloy supported on aluminium hydroxide (Ni-Sn(x)/AlOH; x = Ni/Sn molar ratio) [16]. We have also recently reported the catalytic performance of the Ni-Sn alloy during hydrogenation of biomass-derived levulinic acid in water to -valerolactone (GVL) [17].…”

Development of Nanoporous Ni-Sn Alloy and Application for Chemoselective Hydrogenation of Furfural to Furfuryl Alcohol

“…The chemoselectivity of Ni-Sn alloy catalysts in C=O hydrogenation could be controlled by changing the additive amount of Sn [20,21]. In the present work, we continue to describe the catalytic performances of our Ni-Sn alloy catalysts that were obtained according to the previous reported [20] in the selective hydrogenation of FFald to FFalc.…”
