“…The data presented in Table S2 demonstrate that for all Cu/HPS catalysts, the FF hydrogenation products are FA, furan, and 2‐methylfuran (Scheme a). This is in agreement with the literature data, indicating that copper based catalysts facilitate hydrogenation of the C=O bond due its adsorption on the catalytic site, while the C=C bonds in the furan ring remain unchanged …”

“…In view of high conversion and selectivity of Pd−Cu/HPS‐r, we studied reusability of this catalyst in ten consecutive reactions. Figure demonstrates that both conversion and selectivity to FA decrease by only a couple of percent after ten cycles, indicating enhanced stability of alloy NPs in the HPS pores as well as practically unchanged catalytic performance which exceeds the catalytic performance upon reusability of other catalysts …”

Selective Hydrogenation of Biomass‐Derived Furfural: Enhanced Catalytic Performance of Pd−Cu Alloy Nanoparticles in Porous Polymer

et al. 2020

Here, the development of a new catalyst is reported for the selective furfural (FF) hydrogenation to furfuryl alcohol (FA) based on about 7 nm sized Pd−Cu alloy nanoparticles (NPs) formed in inexpensive, commercially available micro/mesoporous hypercrosslinked polystyrene (HPS). A comparison of the catalytic properties of as‐synthesized and reduced (denoted “r”) catalysts as well as Pd−Cu alloy and monometallic palladium NPs showed a considerable enhancement of the catalytic performance of Pd−Cu/HPS‐r compared to other catalysts studied, resulting in about 100 % FF conversion, 95.2 % selectivity for FA and a TOF of 1209 h−1. This was attributed to the enrichment of the NP surface with copper atoms, disrupting the furan ring adsorption, and to the presence of both zerovalent and cationic palladium and copper species, resulting in optimal hydrogen and FF adsorption. These factors along with exceptional stability of the catalyst in ten consecutive catalytic cycles make it highly promising in practical applications.

“…[5][6][7] Among these furfural derivatives, FFA is one of the key intermediates and has been extensively used to produce resins, vitamin C, synthetic fibres, lysine, lubricants, adhesives, and wetting agents. [8][9] FFA is commonly produced by selective catalytic hydrogenation of FFR by C=O cleavage. However, it can undergo further hydrogenation (C=C cleavage) and deoxyhydrogenation to give side products such as 2-methylfuran (2-MF), furan, tetrahydrofurfuryl alcohol, 2-methyltetrahydrofuran, and tetrahydrofuran.…”

“…Therefore, a catalyst that can selectively hydrogenate the carbonyl group C=O rather than the C=C bonds still presents a considerable challenge. [9][10] For decades, copper-chromite has been the most successful commercial catalyst for FFA production. [11][12][13] However, the chromium trioxide present in the CuÀ Cr catalyst is highly toxic and can lead to severe environmental problems.…”

Hydrogenation of Furfural to Furfuryl Alcohol over Nickel Supported Bentonite Catalyst

In this work, nickel-supported bentonite catalyst was prepared by wet impregnation method followed by activation and reduction. The nickel catalyst showed excellent catalytic activity for hydrogenation of furfural with 98 % selectivity towards furfuryl alcohol. In addition, various reaction parameters such as temperature, time, catalyst loading, solvents, and catalyst recycling, were optimized to enhance furfural conversion and furfuryl alcohol selectivity.

“…However, a monometallic copper catalyst does not have sufficient activity in the process [23], or it is necessary to use high temperature and pressure. Nevertheless, the authors [24] proposed a Cu/SiO 2 catalyst prepared according to [25], that showed 98% selectivity for FA at 100% conversion of furfural at a hydrogen pressure of 0.1 MPa, 130 • C, weight hourly space velocity (WHSV) = 0.4 h −1 . However, total conversion of furfural could be ensured by a low value of WHSV.…”

Highly Active CuFeAl-containing Catalysts for Selective Hydrogenation of Furfural to Furfuryl Alcohol

et al. 2019

CuFe-containing catalysts with different copper oxide content were prepared by fusion of metal salts. The obtained catalyst showed high activity in the hydrogenation of furfural to furfuryl alcohol (FA) in the batch reactor in the presence of isopropanol as a solvent at a temperature of 100 °C and a hydrogen pressure of 6.0 MPa. The yield of FA and furfural conversion are 97% and 98%, respectively. In the solvent-free reaction in the flow-type reactor; the most active catalyst Cu20Fe66Al14 leads to the 96% formation of FA with 100% conversion of furfural at liquid hourly space velocity (LHSV) = 1 h−1; 160 °C and a hydrogen pressure of 5.0 MPa during 30 h. According to the X-ray diffraction (XRD) method, the active component of the spent and fresh Cu20Fe66Al14 catalyst is the same and is represented by metallic copper and Fe3O4-type spinel. Using different methods, the formation of active sites was investigated.
