Creating a new chem. ecosystem based on platform chems. derived from waste biomass has significant challenges; catalysts need to be able to convert these highly functionalized mols. to specific target chems., economical – not relying on large quantities of precious metals – and maintain activity over many cycles. Herein, we demonstrate how Pd/NiO is able to direct the selectivity of furfural hydrogenation and maintain performance at low Pd loading by a unique dual-site mechanism. Sol-immobilization was used to prepare 1 wt% Pd nanoparticles supported on NiO and TiO2, with the Pd/NiO catalyst showing enhanced activity with a significantly different selectivity profile; Pd/NiO favors tetrahydrofurfuryl alc. (72%), whereas Pd/TiO2 produces furfuryl alc. as the major product (68%). D. functional theory studies evidenced significant differences on the adsorption of furfural on both NiO and Pd surfaces. Based on this observation we hypothesized that the role of Pd was to dissociate hydrogen, with the NiO surface adsorbing furfural. This dual-site hydrogenation mechanism was supported by comparing the performance of 0.1 wt% Pd/NiO and 0.1 wt% Pd/TiO2. In this study, the 0.1 and 1 wt% Pd/NiO catalysts had a comparable activity, whereas there was a 10 fold reduction in performance for 0.1 weight% Pd/TiO2. When using TiO2 as the support the Pd nanoparticles are responsible for both hydrogen dissociation and furfural adsorption, and the activity is strongly correlated with the effective metal surface area. This work has significant implications for the upgrading of bio-derived feedstocks, suggesting alternative ways for promoting selective transformations and reducing the reliance on precious metals.

Arumugam, Selvamani; Kuppan, Jayaprakash; Devaraj, Murugan; Arumugam, Sivasamy published the artcile< Fe-Pd-immobilized Al-pillared laponite clay as efficient catalyst for conversion of furfural into tetrahydrofurfuryl alcohol>, Name: (Tetrahydrofuran-2-yl)methanol, the main research area is iron palladium immobilized laponite hydrogenation catalyst furfural tetrahydrofurfuryl alc.

Furfural has been widely reported as a new-generation renewable source for the production of chems. and fuels. In this study, Fe-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 alc. (THFOL) under the mild reaction conditions (H2 pressure- 10 bar, temperature- 60°C and time- 4 h). The synthesized samples were characterized by several physico-chem. techniques. XRD, FT-IR, H2-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 NH3-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 Fe-Pd catalyst showed very low FAL conversion (∼53%) and THFOL selectivity (∼38%), whereas the Al-pillared laponite clay supported Fe-Pd catalyst showed an increase in the FAL conversion and THFOL selectivity up to 95% and 98%, resp. The high performance of Fe-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 chem.

G.; Lassi, Ulla; Prati, Laura published the artcile< A Pt-Mo hybrid catalyst for furfural transformation>, Product Details of C5H10O2, the main research area is platinum molybdenum catalyst furfural hydrogenation.

Furfural is a high-value chem., being the precursor of compounds such as furfuryl alc. and tetrahydrofurfuryl alc. Pt is known as active for furfural hydrogenation, but the high price limits its exploitation and imposes the search for alternatives. Here we presented a Pt/Mo bimetallic system with enhanced catalytic activity for furfural hydrogenation. For comparison, monometallic Mo- and Pt-supported on activated carbon have been prepared by impregnation and sol-immobilization. The bimetallic Pt/Mo was prepared impregnating the Mo-AC catalyst with Pt, using Na2PtCl4 as a precursor, PVA, and NaBH4 as reducing agent. HR-TEM analyses on Pt/Mo catalyst showed Mo-containing agglomerates embedded in the carbon matrix, displaying diffraction fringes with spacing typical of Mo4O11 in the orthorhombic phase, as well as Pt nanoparticles more evenly dispersed in the Mo-AC system compared to bare AC. The Pt/Mo catalyst showed higher activity than both monometallic ones, and it converted 92% of furfural to furfuryl alc. and Et furfuryl ether with 20% and 80% selectivity, resp. However, despite a lower initial activity, the monometallic Mo/AC catalyst showed a complete selectivity to the ether.

Pd-TiO2, Pd-Cu and Pd-Fe activated carbon (AC) supported catalysts were employed for continuous selective hydrogenation of furfural. The effect of reaction parameters on product selectivity and space time yield (STY) was determined Weak acid sites, generated by the Pd-TiO2 catalyst opened the furan ring and resulted in a STY of 134 g Lcat-1 h-1 (610 g kgcat-1 h-1) and 39% selectivity to 5-hydroxy-2-pentanone (5H2P), a hydrogenation product of furan ring opening, in a short residence time (7.6 min) at 180°C and 300 psig. The Pd-Cu and Pd-Fe catalysts were selective towards tetrahydrofurfuryl alc. and furfuryl alc. A STY of 259 g Lcat-1 h-1 (1182 g kgcat-1 h-1) and 42% selectivity to furfuryl alc. was achieved in the presence of the Pd-Cu catalyst at 180°C and 300 psig (3.8 min). The Pd/TiO2/AC catalyst shows promise for continuous production of 5H2P, a building block for many drugs and a precursor to 1,4-pentanediol.

Tetrahydrofurfuryl alc. (THFA) is a kind of high value-added compound in industry, which can be obtained from biomass chem. engineering. However, Synthesis of THFA under mild condition with green hydrogen donors remains a big challenge. In this article, a supported Ni catalyst derived from Ni-Al hydrotalcite-like compounds (HTs) as precursors for the reduction of furfuryl alc. (FA) into THFA with NaBH4 as reducing agent in water was first reported. As a result, Ni/Al2O3-HT exhibited high catalytic activity for the transformation, and THFA was achieved in 100% yield at 60°C for 60 min. Moreover, Ni/Al2O3-HT could be recycled at least seven times without the loss of its activity. Under optimized conditions, the reduction reaction of several furan and ketone compounds was investigated. A possible mechanism for the reduction of FA to afford THFA was also proposed.

The design of efficient catalysts is of important significance for the transformation of biomass into chems. In this work, bimetallic Pd-Co nanoparticles were encapsulated within UiO-66 to form a core-shell Pd-Co@UiO-66 catalyst via a facile one-step strategy. The as-synthesized Pd-Co@UiO-66 catalysts were characterized and applied to the selective hydrogenation of furfural (FUR) to cyclopentanone (CPO). Compared with the monometallic Pd@UiO-66, the Pd-Co@UiO-66 could demonstrate excellent performance with 96% CPO selectivity and 99% FUR conversion at 120°C under 3 MPa H2 pressure for 12 h. It was found that trace Co had synergetic and promoting effects on the catalytic performance. The core-shell catalysts showed more outstanding recyclability than the supported catalysts, which could maintain high CPO yield after 5th runs.

MacIntosh, Kathryn L.; Beaumont, Simon K. published the artcile< Nickel-Catalyzed Vapour-Phase Hydrogenation of Furfural, Insights into Reactivity and Deactivation>, Quality Control of 97-99-4, the main research area is nickel catalytic vapor phase hydrogenation furfural.

Furfural is a key bioderived platform mol., and its hydrogenation affords access to a number of important chem. intermediates that can act as drop-in replacements to those derived from crude oil or novel alternatives with desirable properties. Here, the vapor phase hydrogenation of furfural to furfuryl alc. at 180° over standard impregnated Ni catalysts is reported and contrasted with the same reaction over Cu chromite. While the selectivity to furfuryl alc. of the unmodified Ni catalysts is much lower than for Cu chromite as expected, the activity of the Ni catalysts in the vapor phase is significantly higher, and the deactivation profile remarkably similar. In the case of the supported Ni catalysts, possible contribution to the deactivation by acidic sites on the catalyst support is discounted based on the similarity of deactivation kinetics on Ni/SiO2 with those seen for less acidic Ni/TiO2 and Ni/CeO2. Powder x-ray diffraction is used to exclude sintering as a primary deactivation pathway. Significant coking of the catalyst (∼ 30% over 16 h) is observed using temperature programmed oxidation This, in combination with the solvent extraction anal. and IR spectroscopy of the coked catalysts points to deactivation by polymeric condensation products of (reactant or) products and hydrocarbon like coke. These findings pave the way for targeted modification of Ni catalysts to use for this important biofeedstock-to-chems. transformation.

Alloy structures with high catalytic surface areas and tunable surface energies can lead to high catalytic selectivity and activities. Herein, the synthesis of sponge-like Pd3Pb multiframes (Pd3Pb MFs) is reported by using the thermodynamically driven phase segregation, which exhibit high selectivity (93%) for the conversion of furfural to furfuryl alc. (FOL) under mild conditions. The excellent catalytic performance of the Pd3Pb MF catalysts is attributed to the high surface area and optimized surface energy of the catalyst, which is associated with the introduction of Pb to Pd. D. functional theory calculations show that the binding energy of FOL to the surface energy-tuned Pd3Pb MF is sufficiently lowered to prevent side reactions such as over-hydrogenation of FOL.

Nikul’shin, P. A.; Ershov, M. A.; Grigor’yeva, E. V.; Tarazanov, S. V.; Kuznetsova, S. N.; Repina, O. V. published the artcile< Furfural Derivatives as Fuel Components>, Formula: C5H10O2, the main research area is furfural derivative fuel component additive.

Furfural derivatives prepared from vegetable raw materials have recently become popular as high-performance fuel additives. Furfural oxygenates are particularly of interest. A lot of research was devoted to preparing new materials from furfural, however, there is much to be discovered about their effect on physicochem. properties of fuels. The possibility of using furfural derivatives, obtained by their hydrogenation on copper and nickel catalysts with full conversion of furfural, as additives to fuel is considered in this article. Their impact on antiknock properties and chem. stability is evaluated. Futons are mostly effective in low-octane hydrocarbon bases, such as hydrocracking gasoline, at a concentration of 5-30 weight %. A high concentration of potential resins can lead to the formation of deposits in the combustion chamber of the engine, which, in turn, requires addnl. research.

Zhang, Jinxin; Mao, Donglei; Wu, Dongfang published the artcile< Industrially Applicable Aqueous-Phase Selective Hydrogenation of Furfural on an Efficient TiOx-Modified Ni Nanocatalyst>, Recommanded Product: (Tetrahydrofuran-2-yl)methanol, the main research area is industrially aqueous phase selective hydrogenation furfural titania nickel nanocatalyst.

Because water is involved in the formation of furfural (FFR), aqueous-phase selective hydrogenation of FFR to furfuryl alc. (FOL) has the potential for industrial applications, but it has not yet been well exploited. Here, partially reduced TiOx-modified Ni nanocatalysts were studied. The Ni-TiO2 interaction adjusts the Ni electron structure and affects the catalyst adsorption properties. FFR is adsorbed on the TiOx oxygen vacancy (OV) by C=O, and the FOL selectivity is pos. correlated with the surface OV content. The active H atoms dissociated on Ni spillover to the TiOx surface and then attack the adsorbed FFR C=O. The precise synergistic effect of Ni and OV improves the comprehensive performance of FFR hydrogenation. Under mild conditions, FFR conversion can reach 92.5% and FOL selectivity can be as high as 96.8%. This is an extremely excellent performance of aqueous-phase FFR selective hydrogenation, and thus, the TiOx-modified Ni nanocatalyst is a very promising candidate for industrial applications.
