“…From this point of view, catalysts and experimental conditions are the main factors which impose a crucial influence on the selectivity in the reductive conversion of furfural [4,5] . Supported noble metal (Pt, Pd, Ru and Ir) as well as transition metal (Cu, Fe, Ni) nanoparticles have been proposed as heterogeneous catalysts for the direct hydrogenation (under H 2 pressure) and the catalytic transfer hydrogenation (using an organic molecule as the hydrogen source) of furfural [6–26] . Depending on the metal nature and structure (distribution of exposed active sites, such as edges, corners, terraces), furfural can adopt different adsorption modes on the active surface, [27] which are schematically depicted in Scheme 1 b.…”

Here, tetrakis(hydroxymethyl)phosphonium chloride‐protected colloidal iridium nanoparticles were deposited by sol‐immobilisation on three different supports (CeO2, NiO and TiO2) and were investigated for the liquid‐phase direct hydrogenation (H2 atmosphere) and catalytic transfer hydrogenation – CTH (N2 atmosphere) of furfural to study the effect of the H donor. The occurrence of strong‐metal support interactions in 1 wt % Ir/CeO2 catalyst, as disclosed by XPS, was revealed to be responsible for the high activity observed in the direct hydrogenation (81 % conversion after 6 h) and for the unusual selectivity to 2‐methylfuran (70 %) under CTH conditions. On the other hand, Ir/NiO showed peculiar selectivity to tetrahydrofurfuryl alcohol in both H2 and N2 atmospheres (71 % and 70 %, respectively). The density functional theory calculations further showed that the unique selectivity of Ir/NiO may be ascribed to the adsorption properties of furfural on the support, which activates a dual‐site hydrogenation mechanism.

“…As a result, the design of an effective catalytic system for the conversion of furan derivatives was one of the key problems for biomass conversion. It was reported that the furfural and HMF could be converted to a various of chemicals such as tetrahydrofurfuryl alcohol, [21–23] furfuryl alcohol, [24] furan‐2,5‐dicarbaldehyde, [25] furan‐2,5‐dicarboxylic acid, [26–30] 2,5‐dimethylfuran, [31–34] 1‐hydroxyhexane‐2,5‐dione (HHD), [35–48] cyclopentanone [49–54] and diols derivatives [55–59] . The products covered the areas of aldehydes, ketones, acids, esters, ethers, and diols.…”

The catalytic conversion of furan derivatives, furfural and 5‐hydroxymethylfurfural (HMF), to valuable chemicals is of great importance due to the increase in carbon emissions and decrease in fossil fuels. In this manuscript, 1,2,5‐hexanetriol was transformed to HMF through a two steps procedure. The HMF was first hydrogenated to 1‐hydroxyhexane‐2,5‐dione (HHD). The reaction scale could be enlarged from 1 mmol to 50 mmol of the reactant with a similar yield of HHD, and the purity of HHD was over 95 % after a simple extraction. Then the HHD was hydrogenated to 1,2,5‐hexanetriol on Ru/C at very mild reaction conditions. The parameters of pressure, solvent, the concentration of HHD, reaction time and temperature on the hydrogenation of HHD were investigated to find the optimal reaction conditions. The 1,2,5‐hexanetriol could be obtained from HMF in a one‐pot reaction by removing the Pd/C and adding Ru/C after the HMF hydrogenation step. The fresh and used Pd/C and Ru/C were characterized by XRD, TEM, XPS, and the Ru/C was further characterized by EDS mappings. The characterization showed partial agglomeration of Pd occurred after the Pd/C was used. The Ru/C had a narrow Ru distribution and was stable under the reaction conditions. The Ru/C could be used at least 5 times. This manuscript showed an easy route for the production of valuable chemicals from renewable biomass furan derives.

“…In all the above cases, OMCs were efficiently applied as supercapacitors for energy storage. In addition, the applicability of OMCs can further be enhanced by loading active metals such as nickel and zinc on their surface [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. Common doping methods include wet impregnation and coprecipitation, but both require complex operation procedure and may result in metal leaching [ 20 ].…”

Ni-Doped Ordered Nanoporous Carbon Prepared from Chestnut Wood Tannins for the Removal and Photocatalytic Degradation of Methylene Blue

et al. 2022

View full text Add to dashboard Cite

In this work, Ni-doped ordered nanoporous carbon was prepared by a simple and green one-pot solvent evaporation induced self-assembly process, where chestnut wood tannins were used as a precursor, Pluronic® F-127 as a soft template, and Ni2+ as a crosslinking agent and catalytic component. The prepared carbon exhibited a 2D hexagonally ordered nanorod array mesoporous structure with an average pore diameter of ~5 nm. Nickel was found to be present on the surface of nanoporous carbon in the form of nickel oxide, nickel hydroxide, and metallic nickel. Nickel nanoparticles, with an average size of 13.1 nm, were well dispersed on the carbon surface. The synthesized carbon was then tested for the removal of methylene blue under different conditions. It was found that the amount of methylene blue removed increased with increasing pH and concentration of carbon but decreased with increasing concentration of methylene blue. Furthermore, photocatalytic tests carried out under visible light illumination showed that purple light had the greatest effect on the methylene blue adsorption/degradation, with the maximum percent degradation achieved at ~4 h illumination time, and that the percent degradation at lower concentrations of methylene blue was much higher than that at higher concentrations. The adsorption/degradation process exhibited pseudo second-order kinetics and strong initial adsorption, and the prepared carbon showed high magnetic properties and good recyclability.
