Solvent-mediated selectivity control of furfural hydrogenation over a N-doped carbon-nanotube-supported Co/CoOx catalyst

Composition control of Pd-based bimetallic alloys to boost selective hydrogenation of furfural in aqueous micelles

“…Excessive reduction of the amount of Pd in the alloy catalyst will reduce the efficiency of the catalyst, resulting in poor reaction results. 25,80 Similar to the results of the PdCu catalytic system, when no surfactant was added, the activity of the PdNi catalyst decreased significantly, and outperformed by adding surfactants with the structure of the ether bond and amino or Schiff base (Table 1, entries [18][19][20][21][22][23][24]. Because the concentration of the surfactant can change the reaction process and improve the yield of the product, [81][82][83] the effect of different concentrations of GluM on the catalytic performance was studied.…”

“…17 Therefore, a number of environmentally friendly metal catalysts, e.g., Pd, Ni, Co and Fe, have been employed as alternatives to the Cr component. [18][19][20][21][22][23][24][25][26][27] Although non-noble metal catalysts have attracted much attention due to their abundance and inexpensiveness, they are restricted by the use of potentially toxic organic solvents and harsh reaction conditions. 26,[28][29][30][31][32] Thus, Pd is still the preferred candidate in the selective hydrogenation of FF owing to its high intrinsic activity and low activation energy.…”

Cu/SiO2 synthesized with HKUST-1 as precursor: high ratio of Cu+/(Cu+ + Cu0) and rich oxygen defects for efficient catalytic hydrogenation of furfural to 2-methyl furan

“…On the other hand, the solvent medium plays an important role in product distribution, 53,54 in which the H 2 O generated due to the interaction between FF and the solvent molecules (e.g., MeOH) benefits the ring-opening of FA and the further reaction to obtain CPO. By comparison, the reaction pathway of FA to CPO in THF medium was thus absolutely inhibited because no H 2 O was formed.…”

Synthesis of renewable C–C cyclic oxygenated compounds dedicated for high-density biofuels from biomass-derived cyclopentanone

“…30,31 Admittedly, the use of bio-based platform molecules with a cyclic carbon chain as starting materials for the synthesis of cycloalkanes represents the most straightforward approach to obtain cycloalkanes. 32,33 Cyclopentanone, an attractive compound derived from furfural via Piancatelli rearrangement and hydrogenation, 34,35 represents an ideal feedstock for the synthesis of cycloalkanes. In particular, the self-condensation of cyclopentanone has gained much attention in the field of highdensity fuel production because the obtained products contain two or more cyclic carbon chains.…”
