“…These results suggest that the higher dispersions of Ni-Sn alloy on the TiO2 were formed as roughly depicted in the average Ni3Sn2 (101) crystallite sizes, which were 6 nm ( Table 2). In conclusion, the XRD analysis and H2 measurement results confirm that Ni-Sn alloy phases were also formed on the supports and that their characteristics were consistent with the results observed for the bulk material as reported previously [15]. The results of ammonia-temperature programmed desorption (NH3-TPD) measurements of the synthesized catalysts are summarized in Table 3 and the NH3-TPD profiles are shown in Figure 3 and Figure 4.…”

“…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],…”

“…It was reported that metal species lead more dispersible on support with lower porosity (e.g. TiO2) due to strong interaction between metal and support which will prevent metal aggregation or sintering during thermal treatment [15,23].…”

“…A typical procedure of the synthesis of titanium oxide supported Ni-Sn (1.5 is feeding ratio) alloy catalyst is described as follows [15]: NiCl2·6H2O (7.2 mmol) was dissolved in deionized water (denoted as solution A), and SnCl2·2H2O (4.8 mmol) was dissolved in ethanol/2-methoxy ethanol (2:1) (denoted as solution B) at room temperature. A one-gram titanium oxide (TiO2), solutions A, and B were mixed at room temperature; the temperature was subsequently raised to 50 o C and the mixture was stirred for 12 h. The pH of the mixture was adjusted to 12 through the dropwise addition of an aqueous solution of NaOH (3.1 M).…”

“…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].…”

Selective hydrogenation of dodecanoic acid over supported bimetallic Ni-Sn alloy catalysts into dodecane-1-ol is demonstrated. Bimetallic nickel-tin supported on titanium oxide (Ni-Sn(1.5)/TiO2) and gamma-alumina (Ni-Sn(1.5)/-Al2O3); 1.5 = Ni/Sn molar ratio) were synthesized via hydrothermal method in a sealed-Teflon autoclave reactor at 150 o C for 24 h, then followed by reducing with hydrogen gas at 400 o C for 1.5 h. The synthesized catalysts were characterized by means of XRD, IC-AES, N2-adsorption (BET method), H2-chemisorption, and NH3-TPD. Bimetallic Ni-Sn(1.5)/TiO2 catalyst was found to be effective for hydrogenation of dodecanoic acid (>99 % conversion) to dodecane-1-ol (93% yield) at 160 o C, 30 bar H2, and 20 h and the highest dodecane-1-ol (97 % yield) was obtained at initial pressure of H2, 50 bar. An increase of reaction temperature slightly enhanced the degree of hydrodeoxygenation of dodecanoic acid to produce dodecane over both Ni-Sn(1.5)/TiO2 and Ni-Sn(1.5)/-Al2O3 catalysts.

The chemoselective hydrogenation of alkyne is of great importance in the chemical industry, in which intermetallic compounds (IMCs) have attracted extensive interest as efficient catalysts. Herein, we demonstrate the preparation of several supported Ni–Ga IMCs (Ni3Ga, Ni5Ga3, and NiGa) via a facile in situ reduction of layered double hydroxide (LDH) precursors, which demonstrate significantly improved catalytic activity and selectivity for the selective hydrogenation of phenylacetylene to styrene. The composition and particle size of Ni–Ga IMCs can be tuned by adjusting the Ni/Ga ratio or reduction temperature during the topotactic transformation process of LDHs, and the best catalytic behavior can be obtained over the Ni3Ga IMC with a styrene yield of 87.7 % (particle size=7.2 nm at 40 °C and 0.3 MPa), which is better than that of most of the reported Ni catalysts. The X‐ray absorption fine‐structure characterization and DFT calculations reveal the electron transfer from Ga to Ni and active‐site isolation by Ga in Ni–Ga IMCs, which account for the excellent hydrogenation selectivity. The significantly improved catalytic performance makes Ni–Ga IMC catalysts promising candidates for the selective hydrogenation of alkyne.
