Metal–organic frameworks derived magnetic Fe₃O₄/C for catalytic transfer hydrogenation of furfural to furfuryl alcohol

Abstract

Abstact BACKGROUND Fe based metal organic frameworks (Fe‐MOFs) were prepared by solvothermal method, and carbon loaded Fe3O4 (Fe3O4/C) was prepared by pyrolytic carbonization and carbothermal reduction. RESULTS Various analytical techniques were used to characterize the physicochemical structure of Fe‐MOFs and Fe3O4/C under different solvothermal and calcination conditions. Fe3O4/C was then employed as a catalyst for the catalytic transfer hydrogenation of furfural with alcohol as a hydrogen donor, and the effect of hydrogen donor species, reaction temperature, and reaction time were investigated. CONCLUSION The Fe3O4/C catalyst could be easily collected with a magnet and reused for four runs without significant loss of its catalytic. A possible mechanism for the catalytic transfer hydrogenation of furfural over Fe3O4/C was proposed. © 2020 Society of Chemical Industry (SCI)

Recent advances in the catalytic transfer hydrogenation of furfural to furfuryl alcohol over heterogeneous catalysts

“…Jiang et al fabricated a carbon-supported Fe 3 O 4 catalyst (Fe 3 O 4 /C) via pyrolytic carbonization and carbothermal reduction. 88 FFA selectivity reached 98.5% at 76.4% FF conversion at 473 K and 2 MPa N 2 using isopropanol as the hydrogen donor over Fe 3 O 4 /C, which can be easily collected and reused for four runs without significant loss of catalytic activity. Examination of the hydrogen donor showed that isopropanol had lower reduction potential, leading to higher H proton provision ability than ethanol.…”

Highly Active, Ultra-Low Loading Single-Atom Iron Catalysts for Catalytic Transfer Hydrogenation

“…Some other effects like pyrolysis temperature or H donor were shown in Tables S10 and S11. Strikingly, Fe-ZIF-8-800 catalyst affords 99.6% FF conversion and 96.9% FA selectivity at 120°C in 6 h. This performance is comparable to state-of-the-art catalysts (Table S12) [25,[32][33][34][35][36][37][38][39][40][41][42], signi cantly better than our previous Fe catalysts, named Fe-phen/C-800 [25], and much better than other Fe catalysts under mild conditions (Table S13) [25,[43][44][45][46][47][48][49]. Fe-MOF-5-800 and ZIF-8-800 catalysts give lower FF conversion and FA selectivity and TOF of ca.…”

Recent advances in the conversion of furfural into bio-chemicals through chemo- and bio-catalysis

“…Besides the use of H 2 as a hydrogen source, catalytic transfer hydrogenation (CTH) is a potential alternative protocol for the hydrogenation of furfural to FOL. 93,[98][99][100][101] Zr-based catalysts, [102][103][104][105] CuNi@C, 101 single-atom Ni catalyst, 93 metal-organic framework (MOF) materials, 101,103,106,107 noble metal catalysts such as Pd, Pt, and Ru, [108][109][110][111] and transition metal catalysts such as Fe oxides 112 have been used to catalyze the reaction. MOF-808 has been shown to be the most active catalyst in the CTH of FUR to FOL among the Zr-MOFs due to the facile modication of the metal node mediating the acid-base properties by the introduction of coordinatively unsaturated sites, hydroxyl and methoxy groups in the framework of the Zr-MOF, which favor the adsorption of furfural and 2-propanol.…”
