“…The H 2 ‐TPR profile of as‐synthesized Fe−Pd/Al‐pillared laponite sample indicates the successful loading of Pd and Fe into the Al‐pillared laponite clay structure (Figure ). Therein, the presence of an intense peak near to the 200 °C represent the characteristic reduction of PdO to Pd, whereas a broad peak appeared in the range 470 to 700 °C due to the reduction of Fe 2 O 3 to Fe via two step reduction process (reduction of Fe 2 O 3 to FeO followed by FeO into Fe) . The presence of these Fe particles is expected to show the magnetic properties that make ease separation of catalyst from the liquid reaction medium .…”

Fe‐Pd‐Immobilized Al‐Pillared Laponite Clay as an Efficient Catalyst for the Conversion of Furfural into Tetrahydrofurfuryl Alcohol

Furfural has been widely reported as a new-generation renewable source for the production of chemicals and fuels. In this study, FeÀ Pd immobilized Al-pillared laponite clay material with suitable catalytic properties was explored as an efficient catalyst for the direct conversion of furfural (FAL) into tetrahydrofurfuryl alcohol (THFOL) under the mild reaction conditions (H 2 pressure-10 bar, temperature-60°C and time-4 hrs). The synthesized samples were characterized by several physico-chemical techniques. XRD, FT-IR, H 2-TPR and ICP-OES results revealed the successful loading of those bi-metals into the Al-pillared laponite structure. Acidity of the sample has been thoroughly investigated by NH 3-TPD and FT-IR techniques. The catalytic activity of synthesized samples was thoroughly evaluated for the total hydrogenation of FAL for the production of THFOL. It was observed that pure FeÀ Pd catalyst showed very low FAL conversion (∼ 53 %) and THFOL selectivity (∼ 38 %), whereas the Al-pillared laponite clay supported FeÀ Pd catalyst showed an increase in the FAL conversion and THFOL selectivity up to 95 % and 98 %, respectively. The high performance of FeÀ Pd/Al-pillared laponite catalyst towards the formation of THFOL is not only ascribed to the fine dispersion of Fe and Pd species and their synergistic effect but also due to the high surface area, mesoporosity and suitable acidity of Al-pillared laponite. The recyclability of the catalyst was also explored thoroughly which confirmed their stability. Sustainability of this process lies in the utilization of low-value bio-derived FAL for the production of industrially important THFOL chemical.

“…The catalytic transfer hydrogenation (CTH) process also known as Meerwein-Ponndorf-Verley (MPV) reduction using isopropanol as the hydrogen source is commonly used. Various catalysts, such as Ni, 1 Co-Pd, 2 Cu, 3 Ru, 4,5 Fe, 6 Ir, 7 beta zeolite, 8 and Pd, 9 have been applied for the CTH reaction of carbonyl compounds. The common transition metal-based catalysts oen suffer from complex preparation processes and high reaction temperatures.…”

“…The conversion of furfural to valuable chemicals was attracting more attention as the consuming in fossil resources [2][3][4][5][6][7]. The main products from furfural were cyclopentanone [8][9][10][11][12], furfuryl alcohol (FA) [13][14][15][16], tetrahydrofurfuryl alcohol (THFA) [17][18][19][20][21][22][23][24][25][26][27][28][29][30], 1,2-pentanediol [31][32][33][34][35], furan [36,37], and methyl furan [38]. The THFA was a typical product from furfural through the hydrogenation of C=C and C=O in furfural.…”

“…Guan et al got 98% conversion of FA and 98% selectivity to tetrahydrofurfuryl alcohol under mild condition in ethanol [47]. In a survey of literature, the yield of THFA could reach a high value in both the direct hydrogenation of furfural procedure and the two steps procedure via FA as an intermedia [17][18][19][20][21][22][23][24][25][26][27][28][29][30]. The weakening of the dependence on harsh reaction conditions (high temperature and pressure, organic solvent) was one of the interest points for the production of THFA.…”

Facile Preparation of Pd/UiO-66-v for the Conversion of Furfuryl Alcohol to Tetrahydrofurfuryl Alcohol under Mild Conditions in Water

The hydrogenation of furan ring in the biomass-derived furans is of great importance for the conversion of biomass to valuable chemicals. Fabrication of high activity and selectivity catalyst for this hydrogenation under mild conditions was one of the focuses of this research. In this manuscript, UiO-66-v, in which vinyl bonded to the benzene ring, was first prepared. Then, the uniformly distributed vinyl was used as the reductant for the preparation of Pd/UiO-66-v. The catalyst was characterized by X-ray diffraction, thermogravimetric, N2 physical adsorption/desorption, X-ray photoelectron spectroscopy, scanning electron microscope, transmission electron microscopy, energy dispersive spectrometer elemental mappings, and inductively coupled plasma atomic emission spectroscopy to find the Pd/UiO-66-v had a narrow palladium nanoparticles size of 3–5 nm and maintained the structure and thermal stability of UiO-66-v. The Pd/UiO-66-v was used for the hydrogenation of furfuryl alcohol to tetrahydrofurfuryl alcohol in water. 99% conversion of furfuryl alcohol was obtained with 90% selectivity to tetrahydrofurfuryl alcohol after reacted at 0.5 MPa H2, 303 K for 12 h. The Pd/UiO-66-v was proved to be effective for the hydrogenation of furan ring in furans and could be used for at least five times.
