Biomass-derived 5-alkoxymethylfurfurals (AMFs) are an important kind of high-quality liquid biofuel or diesel additive, which commonly produced by the etherification 5-hydroxymethylfurfural (HMF) with alcohols. To produce various AMFs in a convenient and practical manner, design high-performance catalysts preeminent catalytic universalities is particularly interesting meaningful task. Herein, we developed useful carbonization–coordination–sulfonation strategy, was employed to construct Lewis–Brønsted bifunctional carbonaceous acid catalyst (Zr/GHTC–SO3H). The characterization results demonstrated that Zr/GHTC–SO3H contained strong Lewis acidic sites (Zr4+) Brønsted (−SO3H), could promote HMF then facilitate formation AMFs. Simultaneously, basic (O2–) were dramatically destroyed weakened, restrict transfer hydrogenation improve selectivity Due synergistic effects different active sites, showed excellent performance universality. When etherified methanol, ethanol, n-propanol, isopropanol, n-butanol, sec-butanol, corresponding product yield be up 91.6, 94.8, 93.3, 94.4, 92.9, 92.1% under appropriate reaction conditions, respectively. Moreover, also stable displayed satisfactory reusability. In summary, this work presented special research idea prepare high-efficiency for AMFs, provide significant references production other biomass-derived furanic ethers.

The new insights toward the cascade synthesis of isopropyl levulinate (i-PL), an important biofuel additive and precursor to highly valued γ-valerolactone (GVL), from bioderived furfural (FA) via Meerwein–Ponndorf–Verley (MPV) reduction followed by alcoholysis were studied. For that, a sustainable catalyst nickel exchanged 12-tungstophosphoric acid anchored zeolite HY was synthesized characterized different techniques such as FTIR, UV–vis–NIR, TGA, BET, XRD, 31P NMR, HRTEM, EDX, XPS. total acidity well types studied NH3-TPD pyridine FTIR. exhibited its exceptional performance attain 72% yield i-PL which successfully implied strategy "say no external H-source" leading remarkable turnover number (1385). features boosted regeneration reuse. comparison study highlighted superiority in terms employing non-noble metal highest desired product. reaction pathway also proposed on basis control experiments.
