Hydrogen-Free Catalytic Reduction of Biomass-Derived 5-Hydroxymethylfurfural into 2,5-Bis(hydroxymethyl)furan Using Copper–Iron Oxides Bimetallic Nanocatalyst

“…1,2 As a result, there is a growing demand for the conversion of renewable resources into chemicals and fuels. 3,4 As the only renewable carbon source available on earth, lignocellulosic biomass is an excellent candidate to be transformed to a high value chemicals and fuels. 5−7 Among the most promising biomass-derived chemicals, HMF is recognized as an important intermediate for production of several high-value chemicals through various chemical transformation processes including hydrogenation, etherification, amination, oxidation, isomerization, condensation, and cyclization.…”

“…Recently, climate change and severe environmental problems have been connected with the utilization and consumption of the conventional fossil energy sources used in the traditional chemical industries, such as petroleum and natural gas. , As a result, there is a growing demand for the conversion of renewable resources into chemicals and fuels. , As the only renewable carbon source available on earth, lignocellulosic biomass is an excellent candidate to be transformed to a high value chemicals and fuels. − Among the most promising biomass-derived chemicals, HMF is recognized as an important intermediate for production of several high-value chemicals through various chemical transformation processes including hydrogenation, etherification, amination, oxidation, isomerization, condensation, and cyclization. − HMF is mainly prepared through acid-catalyzed dehydration of sugars in various organic solvents. , HMF possesses three different unique functional groups (hydroxyl, aldehyde, and aromatic furan ring) which make it flexible for further catalytic valorization into a high range of chemicals . The hydrogenation process of HMF produces a variety of different useful products, such as BHMF, 2,5-dimethyltetrahydrofuran, 2,5-dimethylfuran, and 1,6-hexanediol. ,− …”

Transfer Hydrogenation of Furfural to 2-Methylfuran over a Cu-BTC-Derived Catalyst with Isopropanol as a Hydrogen Donor

“…Both metallic and acidic sites must be present in the catalyst for the 2-MF formation . Several transition metals, including Ru, Pd, Ni, Cu, Ir, Fe, and Mg, have been explored for 2-MF production, with Cu receiving significant research attention due to its abundance, cost-effectiveness, and its ability to adsorb furfural via the η 1 -( O )-aldehyde configuration, essential for selective 2-MF formation. , However, conventional methods for producing metallic and Lewis acidic sites in Cu-based catalysts often involve high-temperature H 2 reduction, − which poses significant safety hazards and infrastructure costs. Recently, catalysts derived from metal–organic frameworks (MOFs) have become a focal point of research due to their generally high surface areas, accessible porosity, and potential tunability .…”

Hydrodeoxygenation of Furfural over Unsupported, SiO2‐supported or Metal‐promoted Mo Carbides: Tunning the Selectivity between 2‐Methylfuran and C10 Furoins Diesel Precursors

“…[1,2] The HDO of furfural has been reported to occur over Cu, [11][12][13] Ni, [14,15] and bimetallic catalysts, [16][17][18] as well as noble metals, such as Re, [19][20][21] Ru, [22][23][24] Ir, [25] Pt [26] and Pd. [27] In general, Cu-based catalysts are selective in breaking CÀ O bonds, because they adsorb furfural in the h 1 -(O) configuration via the aldehyde function, [1] but they exhibit poor ability to dissociate hydrogen and low activity. In contrast, Ni-based catalysts readily dissociate hydrogen, [28] but it is poorly selective as it can hydrogenate the aromatic furan ring of furfural due to its adsorption in the h 2 -(C,O)-aldehyde mode, leading the catalyst to interact with both the aldehyde group and the furan ring.…”
