Promoted Hydrogenolysis of Furan Aldehydes to 2,5‐Dimethylfuran by Defect Engineering on Pd/NiCo₂O₄

Integrated Cascade Process for the Catalytic Conversion of 5‐Hydroxymethylfurfural to Furanic and TetrahydrofuranicDiethers as Potential Biofuels

“…In particular, by‐products deriving from hydrogenolysis were identified, such as the 2,5‐dimethyltetrahydrofuran (DMTHF) (Figure S16), whose amount increased with the prolonging of time, analogously to the other by‐products, up to the yield of about 16.9 mol% after 300 min. In fact, a recent work found that the C−O bond cleavage of 2,5‐bis(alkoxymethyl)furans is easier and faster than the respective diols; thus, the hydrogenolysis was promoted in this reaction [37] . In order to investigate the role of temperature and promote the hydrogenation respect to the hydrogenolysis, the temperature was decreased to 80 °C, keeping the pressure at 60 bar (Figure 7B).…”

2D MOF with Compact Catalytic Sites for the One‐pot Synthesis of 2,5‐Dimethylfuran from Saccharides via Tandem Catalysis

“…When interacting with Pd/NUS and Pd/C, C=O group peaks redshifted from 1668 cm À 1 to 1642 cm À 1 over Pd/NUS, and to 1649 cm À 1 over Pd/C (Figure 5D). [62,63] However, the position of the furan ring group is invariable at 1043 cm À 1 over Pd/NUS, but redshifted to 1020 cm À 1 over Pd/C. The results indicate that both the furan ring and C=O groups of 5-HMF are adsorbed, activated, and hydrogenated on the Pd/C surface, but only C=O group interact with MOF-based catalyst, which ensures the highly efficient preparation of 2,5-BHMF and inhibits the formation of BTHMF.…”

Spinel-based catalysts for the biomass valorisation of platform moleculesviaoxidative and reductive transformations

“…Recently, Deng and coworkers engineered a multifunctional Pd supported on NiCo 2 O 4 catalyst by hydrogen plasma etching and phosphonation. 90 Both H 2 plasma etched and phosphonated catalysts were effective in the hydrogenation of HMF. However, the phosphonated Pd/NiCo 2 O 4− x –P catalyst (surface area of 106.8 m 2 g −1 ) was more selective in producing DMF (90.5% selectivity) than the H 2 plasma etched Pd/NiCo 2 O 4− x –H catalyst (76.9% DMF selectivity) (Table 8, entry 9).…”
