“…The Cu 2p XPS spectrum showed three characteristic sets of peaks, each having a 2:1 area ration for the 2p 3/2 and 2p 1/2 peaks. The Cu 2p 3/2 ; Cu 2p 1/2 and satellite peaks at 932.6, 952.5 and 942.1 eV, respectively, indicate the presence of Cu species exists in the form of Cu 0 (2p 3/2 = 932.8 eV, 2p 1/2 = 952.5 eV) and Cu 2+ (2p 3/2 = 934.5 eV, 2p 1/2 = 954.3 eV) in CuO or Cu 2 AlO 4 ( Figure 5B ) ( Shang et al, 2020 ; Umasankar et al, 2020 ). The Co 2p XPS spectrum ( Figure 5C ) showed two distinct sets of peaks: Co 2+ (2p 3/2 = 781.9 eV, 2p 1/2 = 796.8 eV) and Co 3+ (2p 3/2 = 780.3 eV, 2p 1/2 = 795.2 eV).…”

“…Based on the results, in can be concluded that cobalt in the samples is closely associated with copper and nickel. These interactions promote the reduction of Co and were expected to modify the performance of the catalyst ( Gupta et al, 2020 ; Umasankar et al, 2020 ). The used CuCoNiAl-MMO-3 catalyst showed TPR peaks at 330, 418, and 680°C.…”

The catalytic hydrogenolysis of 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF) is a promising route towards sustainable liquid fuels with a high energy density. Herein, a novel CuCoNiAl-containing mixed metal oxide catalyst (CuCoNiAl-MMO) was prepared by calcination a layered double hydroxide (LDH) precursor in N2 at 500 °C, then applied for the catalytic hydrogenolysis of HMF to DMF. The effects of reaction time, reaction temperature and hydrogen pressure on DMF selectivity were investigated. Under relatively mild reaction conditions (180°C, 1.0 MPa H2, 6.0 h), CuCoNiAl-MMO showed both a high initial activity and selectivity for hydrogenolysis of HMF to DMF, with HMF conversion rate of 99.8% and DMF selectivity of 95.3%. Catalysts characterization studies using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) revealed the presence of various metal oxides and metallic copper on the surface of the CuCoNiAl-MMO catalyst, with the presence of mixed metal-oxide-supported metallic Cu nanoparticles being responsible good hydrogenolysis activity of the catalyst for selective DMF synthesis.

“…[165] In NiÀ Cu/SBA-16 bimetallic catalyst prepared by incipient wetness impregnation, the added Cu improved the Ni reducing ability and minimized the carbon deposition. Nevertheless, due to the weak hydrogenolysis capacity, only 60.7 % yield of DMF was provided by the optimized 5 wt %Ni-12wt %Cu/SBA-16 at 483 K, 2 MPa of H 2 in 4 h. [166] The individual metal particles in catalysts prepared by wet impregnation can hardly bear uniform composition. Some Ni-rich particles limited the DMF selectivity.…”

The catalytic conversion of 5-hydroxymethylfufural (HMF), one of the vital platform chemicals in biomass upgrading, holds great promise for producing highly valuable chemicals through sustainable routes, thereby alleviating the dependence on fossil feedstocks and reducing CO 2 emissions. The reductive upgrading (hydrogenation, hydrogenolysis, ring-opening, ring-rearrangement, amination, etc.) of HMF has exhibited great potential to produce monomers, liquid fuel additives, and other valuable chemicals. Thermocatalytic conversion has a significant advantage over photocatalysis and electrocatalysis in productivity. In this Review, the recent achievements of thermo-reductive transformation of HMF to various chemicals using heterogeneous catalytic systems are presented, including the catalytic systems (catalyst and solvent), reaction conditions, (reaction temperature, pressure, etc.), and reaction mechanisms. The current challenges and future opportunities are discussed as well, aiming at guiding the catalyst design and practical scalable productions.

Catalytic Upgrading of Bio‐Based 5‐Hydroxymethylfurfural to 2,5‐Dimethylfuran with Non‐Noble Metals

et al. 2021

View full text Add to dashboard Cite

2,5-Dimethylfuran (DMF) is considered one of the most promising liquid transport fuels due to its high energy density, high boiling point, high octane number, and immiscibility with water. It can be obtained mainly by hydrogenolysis of biomass-derived 5-hydroxymethylfurfural (HMF) over metal catalysts. This review describes the latest research progress of developing various nonnoble metal catalytic materials for hydrogenolysis of HMF to produce DMF. The effects of different carriers (e.g., carbon materials, nitrogen-doped carbon materials, and metal oxides), the bimetallic synergistic effect, and catalyst type on the catalyst activity are systematically introduced. The reaction paths of producing DMF from HMF affected by reaction parameters such as non-noble metals, hydrogen donors, and temperature are discussed. In addition, potential directions for the large-scale industrial production and application of DMF are proposed.
