“…And the absorption band at 564 cm -1 is an indication of the presence of Si-O-Fe; this band overlaps the Fe-O band of the magnetite [18]. The structure of the Keggin ions of [PW 12 O 40 ] 3is well known, and their bands have been reported in previous works [23,24] (they are also detailed in Supplementary Material). In the sample Fe 3 O 4 @SiO 2 @SiO 2 /TPA 400N2 , they are overlapped by the wide bands originated from the silica network [20,22].…”

Magnetic materials based on Keggin heteropolyacids immobilized on mesoporous silica-coated magnetite particles with a core-shell structure were synthesized. The activity of the catalyst was studied in the esterification reaction of levulinic acid with n-butanol, and its kinetics was studied by the systematic variation of several reaction parameters, such as stirring speed, catalyst loading, molar ratio of reactants, and temperature. It was also seen that the reaction was free from any external mass transfer as well as intraparticle diffusion limitations and was intrinsically kinetically controlled. A second-order kinetic equation was found to be consistent with the experimental data. Also, an experimental activation energy of 17 kcal/mol was found. A solvent-free condition for this reaction has also added the green chemistry perception to the reaction. In addition, the resulting catalyst can be used repeatedly without significant decrease in activity.

“…Carboxylic acids can also be produced via oxidation from FUR. Furoic acid (employed in the pharmaceutical, agrochemical and cosmetic fields) and maleic acid (an important raw material employed in the manufacture of textiles, food additives, plasticizers, bulk‐drugs and agricultural chemicals) can be formed from FUR adding O 2 as an oxidant.…”

Recent Advances in the Catalytic Production of Platform Chemicals from Holocellulosic Biomass

This Review discusses novel catalytic pathways of lignocellulosic biomass to value‐added chemicals including biomass‐derived sugar alcohols, organic acids, furans and biohydrocarbons. These production approaches are undertaken by biological, chemical and thermochemical transformations or a combination of them. Nevertheless, the majority of research in this area is focused on the design of heterogeneous catalysts to convert value‐added products from holocellulosic biomass. Biorefineries represent the peak of biomass processes in order to produce valuable chemicals and liquid fuels avoiding the utilization of corroding and toxic elements. The aim of the present Review is to offer the readers a broad overview of recent holocellulosic‐based chemical and fuels production technologies via heterogeneous catalysis. There is also an overview of the economic aspects to efficiently produce these platform chemicals at industrial scale. To summarize this Review, an outlook and conclusions of the reported processes to date is provided.

As a result, many efforts have been devoted to exploring the conversion of furfural into 2‐furoic acid recently.…”

Electrocatalysis of Furfural Oxidation Coupled with H₂ Evolution via Nickel‐Based Electrocatalysts in Water

et al. 2017

Electrocatalytic water splitting has been widely considered as a promising approach to produce clean H2. The anodic half reaction of water splitting, the O2 evolution reaction (OER), is the kinetic bottleneck of the overall process and its product O2 is not of high value. Herein, we report a novel strategy to replace OER with a thermodynamically more favorable anodic reaction, furfural oxidation to 2‐furoic acid. Furfural is one of the dehydration products of biomass and its oxidation product 2‐furoic acid has many industrial applications. A bifunctional electrocatalyst of Ni2P‐derived arrays on nickel foam (Ni2P/Ni/NF) was developed for the integrated electrocatalysis of both furfural oxidation and H2 production. When Ni2P/Ni/NF acts as the electrocatalyst for both anode and cathode, nearly 100 % Faradaic efficiencies for H2 evolution and furfural oxidation were obtained. Such an integrated electrolysis catalyzed by Ni2P/Ni/NF required an applied voltage ≈110 mV smaller than that of pure water splitting to achieve the current density of 10 mA cm−2, together with robust stability. Overall, our novel electrolyzer produced valuable products at both electrodes (H2 at cathode and 2‐furoic acid at anode) and may extend to the coupling of H2 evolution with many other valuable organic oxidation reactions.
