Pd nanoparticles on carbon nitride-graphene for the selective electro-oxidation of glycerol in alkaline solution

A hybrid support consisting of carbon nitride and graphene (CNx/G) is prepared by annealing polypyrrole/GO at 800 °C. Pd nanoparticles (NPs) are then loaded onto the support by a microwave-polyol method. Pd-CNx/G is used as a catalyst for glycerol electro-oxidation in 0.5 M NaOH aqueous solution. Electrochemical characterization and product analysis by high-performance liquid chromatography show that, in comparison to Pd NPs supported on carbon black, Pd NPs on a support containing nitrogen atoms has the ability to promote selectivity toward C3 products as well as increase activity. The main factors influencing the selectivity and activity are also discussed.

Metal nanoparticles on carbon based supports: The effect of the protective agent removal

The sol immobilization technique is widely employed for the synthesis of size- and morphology-controlled supported nanoparticles. The protective agent adsorbed on the surface of nanoparticles can substantially affect the catalytic performances, by limiting the access to the active sites as well as by influencing metal–support and reactant–metal interactions, thus altering not only the activity but also the selectivity of the reaction. Herein, we studied the effect of the capping agent (specifically polyvinyl alcohol, PVA) removal on the catalytic activity and selectivity of gold nanoparticles supported on different carbon based materials using the glycerol oxidation as test reaction.

Toward the electrochemical valorization of glycerol: Fourier transform infrared spectroscopic and chromatographic studies

Glycerol electrooxidation reaction has been investigated by electrochemical, spectroelectrochemical, and chromatographic methods on palladium-nickel and palladium-silver nanoparticules supported on carbon Vulcan XC 72R. These materials, prepared by the so-called "Bromide Anion Exchange" method, exhibited high activity toward the glycerol electrooxidation in alkaline medium showing furthermore an important shift of the onset potential toward low potential values. Electrolysis coupled with high-performance liquid chromatography (HPLC) and in situ Fourier transform infrared spectroscopy (FTIRS) measurements have been used to determine the various compounds generated in the oxidative conversion of this three hydroxyl groups carbon molecule. Some products with high added value such as glycerate and tartronate have been identified. In situ FTIRS results have furthermore shown the pH decrease in the thin layer near the electrode. These results will positively serve as guidelines for future works on the potential use of glycerol in fuel cell devices in a cogeneration of high value chemicals and energy process.

Production of glyceric acid by gluconobacter sp. NBRC3259 using raw glycerol

Gluconobacter sp. NBRC3259 converted glycerol to glyceric acid (GA). The enantiomeric composition of the GA produced was a mixture of DL-forms with a 77% enantiomeric excess of d-GA. After culture conditions, such as initial glycerol concentration, types

Deinococcucins A-D, Aminoglycolipids from Deinococcus sp., a Gut Bacterium of the Carpenter Ant Camponotus japonicus

Four new aminoglycolipids, deinococcucins A-D (1-4), were discovered from a Deinococcus sp. strain isolated from the gut of queen carpenter ants, Camponotus japonicus. The structures of deinococcucins A-D were elucidated as a combination of N-acetyl glucosamine, 2,3-dihydroxypropanoic acid, and an alkyl amine with a C16 or C17 hydrocarbon chain primarily based on 1D and 2D NMR and mass spectroscopic data. The exact location of the olefinic double bond in deinococcucins C and D (3 and 4) was assigned based on the liquid chromatography-mass spectroscopy data obtained after olefin metathesis. The absolute configurations of the N-acetyl glucosamine and 2,3-dihydroxy moieties were determined through gas chromatography-mass spectroscopy analysis of authentic samples and phenylglycine methyl ester-derivatized products, respectively. Deinococcucins A and C displayed significant induction of quinone reductase in murine Hepa-1c1c7 cells.

The Role of Ruthenium on Carbon-Supported PtRu Catalysts for Electrocatalytic Glycerol Oxidation under Acidic Conditions

A series of binary PtRu catalysts with different Pt/Ru atomic ratios (from 7:3 to 3:7) were synthesized on a carbon support using the colloidal method; they were then used for electrooxidation of glycerol in acid media. X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray absorption spectroscopy analyses were used to investigate particle size, size distribution, and structural and electronic properties of the prepared catalysts. Ru added to the Pt-based catalysts caused structural and electronic modifications over the PtRu alloy catalyst formation. The electrocatalytic activities of PtRu/C series catalysts were investigated using cyclic voltammetry. The Pt5Ru5/C catalyst shows enhanced catalytic activity at least 40 % higher than that of the Pt/C catalyst, with improved stability for glycerol electrooxidation; these improvements are attributed to structural and electronic modifications of the Pt catalysts. Using an electrocatalytic batch reactor, product analysis after the oxidation reaction was performed by high-performance liquid chromatography to determine and compare the reaction pathways on the Pt/C and PtRu/C catalysts. To understand different catalytic activities of glycerol oxidation on the PtRu alloy surfaces, density functional calculations were performed.

A novel mechanism for the oxidation of erythro-series pentoses and hexoses by N-arylbromosulphonamides in alkaline medium

Kinetic studies of the oxidation of D-mannose, D-glucose, D-fructose, L-arabinose and D-ribose by bromamine-T (sodium N-bromo-p-toluenesulphonamide or BAT) and bromamine-B (sodium N-bromobenzenesulphonamide or BAB) in alkaline medium were investigated at 30°C. The rate of the reaction was first order both with respect to the oxidant and the sugar and second order with respect to [HO-]. The addition of the reaction product, p-toluenesulphonamide (PTS) or benzenesulphonamide (BSA), and the variation of ionic strength of the medium have no effect on the rate. The rate decreases with decrease in dielectric constant of the medium and values of dAB, the size of activated complex, were calculated. Proton inventory studies were made in H2O-D2O mixtures. The activation parameters of the reaction were computed from Arrhenius plots. HPLC and GLC-MS analysis of the products indicated that the sugars were oxidized to a mixture of aldonic acids consisting of arabinonic, ribonic, erythronic and glyceric acids. A general mechanism consistent with the observed results has been proposed.

Plasmonic Oxidation of Glycerol Using Au/TiO2 Catalysts Prepared by Sol-Immobilisation

Abstract: Au nanoparticles supported on P25 TiO2 (Au/TiO2) were prepared by a facile sol-immobilisation method and investigated for the surface plasmon-assisted glycerol oxidation under base-free conditions. The Au/TiO2 samples were characterized by UV–vis spectroscopy and transmission electron microscopy. Catalysts were prepared using polyvinyl alcohol as stabiliser as well as in the absence of polymer stabiliser. Both the conversion and the reaction selectivity are affected by the plasmon-assisted oxidation and there is an interplay between the presence of the stabiliser and the Au nanoparticle size.

Serinolamides and Lyngbyabellins from an Okeania sp. Cyanobacterium Collected from the Red Sea

NMR- and MS-guided fractionation of an extract of an Okeania sp. marine cyanobacterium, collected from the Red Sea, led to the isolation of four new metabolites, including serinolamides C (1) and D (2) and lyngbyabellins O (3) and P (4), together with the three known substances lyngbyabellins F (5) and G (6) and dolastatin 16 (7). The planar structures of the new compounds were determined using NMR and MS analyses. The absolute configurations of 1 and 2 were determined by Marfey's analysis of their hydrolysates. The absolute configuration of 3 was ascertained by chiral-phase chromatography of degradation products, while that of 4 was determined by comparison to 3 and 5. The cytotoxic and antifouling activities of these compounds were evaluated using MCF7 breast cancer cells and Amphibalanus amphitrite larvae, respectively. Compounds 3, 4, and 7 exhibited strong antifouling activity, and 3 and 7 were not cytotoxic. A structure-activity relationship was observed for the cytotoxicity of the lyngbyabellins with the presence of a side chain (4 is more active than 3) leading to greater activity. For the antifouling activity, the acyclic form without a side chain (3) was the most active.

Combined EC-NMR and in Situ FTIR Spectroscopic Studies of Glycerol Electrooxidation on Pt/C, PtRu/C, and PtRh/C

Glycerol, a byproduct of biodiesel production, is an industrial waste because of its excess yield. Electrooxidation of glycerol is a promising way to utilize glycerol - through harvesting electric energy as fuels in a fuel cell or hydrogen as sacrificial agent in electrolysis cell - while generating valuable chemicals. Here, we report a detailed mechanistic study of the glycerol electrooxidation reaction (GOR) on a series of Pt/C, PtxRuy/C, and PtxRhy/C nanocatalysts synthesized by NaBH4 reduction. The EC cyclic voltammetry characterization indicates that alloying Ru with Pt greatly enhanced the GOR activity, especially at low potential, but not as much with alloying Rh, as compared with Pt/C. In situ FTIR and 13C NMR spectroscopies were used to investigate the GOR mechanism at a molecular level. The results demonstrate that the selectivity of products depends on the type of catalysts and the oxidation potential. Although both PtRu/C and PtRh/C could accelerate the oxygen insertion reactions that led to higher selectivity of carboxylic acids, tartronic acid was more favored at high potential on the PtRh/C surface.
