Last year the UG was ranked on the 80th place. The instrument was used, range from 0 to 75°. It is the, that Cu was used as metal in the synthesis of Me-PANI-AC electro-, catalysts, whereas the Fe- and Co-containing have already been re-, ported as electrocatalysts for the oxygen reduction reaction and for the, were tested for the electrocatalytic reduction of nitrobenzene, with the. Most useful is the reduction … The peaks in the XRD pattern are, and S3). Selective reduction of nitrobenzene to aniline over electrocatalysts based on nitrogen-doped carbons containing non-noble metals. extended to the synthesis of other metal NPs@NHCS composites for a variety of advanced applications. http://dx.doi.org/10.1016/0013-4686(93)85073-8, http://dx.doi.org/10.1016/S0925-8388(02)01359-2, http://dx.doi.org/10.1007/s11783-015-0782-1. Among the S, Se and Te based iron chalcogenised carbonyl clusters, the diselenide cluster was found to be most efficient and produce almost 90% yield of the desired amino product, the disulfide cluster was also found to be significantly active, produce the 85% yield of amino product, while the ditelluride cluster was not found to be active and produced only 49% yield of the desired product. Characterisation with a combination of techniques (FT-IR and Raman spectroscopy, XRD, N2-physisorption, XPS and ToF-SIMS) showed that the materials exhibit promising features as electrocatalysts for the NO reduction reaction, as they contain the desired isolated FeNxCy sites and have a relatively high degree of graphitisation, which grants good electrical conductivity. When evaluated as anode material for sodium ion batteries (SIBs), the Co9S8/C nanocmposite electrode displays a reversible capacity of ~567 mAh g-1 in the initial cycle and maintains a reversible capacity of ~320 mAh g-1 after 30 cycles, indicating a larger capacity and stable cycling performance. 2 (2012) 884, L.W. On the other, with previous applications of Fe-PANI-AC electrocatalysts in the oxygen, reduction reaction and in the reduction of nitric oxide to hydro-, work, Cu-PANI-AC-A, was employed in a chronoamperometric test in, which 54% conversion of nitrobenzene with a selectivity of 82% to-, at room temperature. The University of Groningen has made energy one of its three main research themes and makes major contributions to the transition to sustainable production and consumption of energy. Co-PANI-AC-B and -C probably also contain small, amounts of metallic cobalt, as suggested by the low intensity peak, the face-centred cubic system. Mitchell, S.A. Campbell, Investigation of CoS, catalysts for the oxygen reduction reaction, J. Catal. balt(II) chloride hexahydrate (98%, reagent grade, Sigma Aldrich), ammonium peroxydisulphate (98%, Acros Organics), sulphuric acid, Fisher Chemical), perchloric acid (70% aqueous solution, Sigma, Metal-containing N-doped carbon materials were prepared through, procedures inspired by a previously reported method (, lative to aniline), and the metal precursor, (1:1 or 1:4 molar ratio re-, lative to aniline) were added to the synthesis mixture. Compared with other catalysts, the strongest binding strength of Ph-NOOH* with PtN3/G is responsible for its superior catalytic activity towards NBER, which can be deeply understood on the basis of the corresponding electronic structures analysis. Most importantly, unprecedented selectivity to aniline was obtained (82%, as determined by chronoamperometry) with this electrocatalyst in a half-cell setup. free selective hydrogenation of nitrobenzene to aniline: an unexpected catalytic. Here, hydrazine hydrate (N2H4⋅H2O) is used as the reducing agent which generates harmless by-products such as N2 and water. The composite material Sc/4ND-CNxNT has an excellent quality as a media for hydrogen storage characterized by strong binding such that each Sc can hold up to five hydrogen molecules. By means of density functional theory studies, it has, been determined that the Me-N bond strength decreases in the order Fe-, copper oxides/hydroxides are strongly anchored to the composite ma-, terial, as shown by the fact that they do not get removed during the acid, treatment, whereas in the case of Co-PANI-ACs a major drop in the, content of oxides/hydroxides is observed upon treatment with H. As determined by deconvolution of the high resolution N 1s XPS signals with MultiPak. Copyright © 2010 Elsevier B.V. All rights reserved. For comparison, the electrochemical performance of Co9S8 and Co9S8/C samples synthesized by solid-state reaction are also displayed. Charge compensation was done by inter-, out using the software supplied by the instrument manufacturer, Sur-, faceLab (version 6.5). The materials were systematically evaluated for catalytic oxidation of metformin, sulfamethoxazole, and phenol and reductive hydrogenation of 4-nitrophenol and 1-nitronaphthalene as model pharmaceutical and industrial pollutants. The carbon intercalation and N coordination optimize the interfacial properties of Co for catalysis.
