Chelate formation and stability analysis of cobalt, nickel and copper with lomatiol

The pH-metric studies on the interaction of divalent metal cations, Co (II), Ni (II) and Cu (II) with lomatiol have been performed under the thermodynamic conditions achievable at constant ionic strength and infinite dilution in which a mole of divalent metal, combined with 02 mol of lomatiol. Lomatiol being bidentate could replace two water molecules at a time. The values of stepwise formation constants showed no conspicuous difference at 25 degrees C and 35 degrees C, and the complexes, registered a decrease in their stability values suggesting the low temperature as a favorable condition under which the chelation of metal with lomatiol is feasible. The reaction takes place without the use of any specific catalyst although under alkaline conditions. The reactions of lomatiol with metal cations in solution had been adjudged as the spontaneous reaction on account of the negative Delta G value in all the metal lomatiol systems. Also the study showed the positive experimental values of entropy changes in all the systems and negative value of free energy. The continuous fall in the values of the stepwise formation constants (k(1) > k(2) > k(3)) in the divalent metal-lomatiol system has been assigned to the statistical factor. (C) 2020 The Author(s).

Charge-distribution modulation of copper ferrite spinel-type catalysts for highly efficient Hg-0 oxidation

Hg-0 catalytic oxidation is an attractive approach to reduce mercury emissions from industrial activities. How-ever, the rational design of highly active catalysts remains a significant challenge. Herein, the charge distribution modulation strategy was proposed to design novel catalysts: copper ferrite spinel-type catalysts were developed by introducing Cu2+ cations into octahedral sites to form electron-transfer environment. The synthesized catalysts with spinel-type stoichiometry showed superior catalytic performance, and achieved > 90 % Hg-0 oxidation efficiency in a wide operation temperature window of 150-300 degrees C. The superior catalytic performance was closely associated with the mobile-electron environment of copper ferrite. Hg-0 oxidation by HCl over copper ferrite followed the Eley-Rideal mechanism, in which physically adsorbed Hg-0 reacted with active chlorine species. Density functional theory calculations revealed that octahedral Cu atom is the most active site of Hg-0 adsorption on copper ferrite surface. Both direct oxidation pathway (Hg* -> HgCl2*) and HgCl-mediated oxidation pathway (Hg* -> HgCl* -> HgCl2*) played important role in Hg-0 oxidation over copper ferrite. HgCl2* formation was identified as the rate-limiting step of Hg-0 oxidation. This work would provide a new perspective for the development of admirable catalysts with outstanding Hg-0 oxidation performance.

Steam reforming of ethanol over copper-zirconia based catalysts doped with Mn, Ni, Ga

The activity toward hydrogen production in steam reforming of ethanol (SRE) reaction has been evaluated for CuO/ZrO2 catalysts doped with Mn, Ni, Ga at 350 degrees C. The copper based catalysts were synthesised by co-precipitation method at constant pH = 7 and fixed (wt.%) CuO/ZrO = 2.3. The catalysts were characterised by means of N-2 adsorption, temperature programmed reduction (H-2-TPR), N2O dissociative chemisorption, X-ray diffraction (XRD), CO2 temperature programmed desorption (CO2-TPD), and temperature programmed oxidation (TPO). It has been found that copper based catalysts exhibit high ethanol conversion in SRE (>86%) at 350 degrees C. Due to basic character of catalysts, the formation of acetaldehyde is observed. The CuO/ZrO2 catalyst modification with dopants increases the hydrogen yield with maximum (52%) for CuO/ZrO2/NiO. The addition of Ni changes the distribution of carbon-containing products. In this case, the increase in selectivity to CO, CO2 and CH4 is observed whereas selectivity to acetaldehyde is significantly decreased. This shows that presence of Ni facilities the C-C bond cleavage. On the other hand, the formation of acetic acid is limited upon addition of Mn and Ga. For all modified catalysts, decrease in carbon deposition rate during SRE is pronounced according to TPO experiments. The modification of Cu/Zr with Mn, Ni and Ga causes the decrease in copper particle size, which hinders the carbon deposit formation. (C) 2020 Hydrogen Energy Publications LLC.

Design and Synthesis of La-Modified Copper Phyllosilicate Nanotubes for Hydrogenation of Methyl Acetate to Ethanol

A novel La modified copper phyllosilicate nanotubes (Cu-PSNT) were designed for hydrogenation of methyl acetate (MA) to ethanol. La/Cu-PSNT catalysts were prepared by the focus on the formation of unique tubular structure and evolution of copper species by varying La loading. The physicochemical properties and distribution of the copper species were systematically studied through several characterizations. The results showed that the Cu-PSNTs catalyst exhibited superior catalytic activity in comparison with the catalyst prepared by traditional ammonia-evaporation (AE method). Moreover, the addition of La greatly influenced the dispersion of active copper species and the ratio of Cu-0/(Cu-0 + Cu+) through the strong interplay between copper and lanthanum species. An appropriate amount of La could increase the surface area of active copper and enhance the ability to dissociate H-2 on La/Cu-PSNT catalyst, which were essential to increase the activity and stability in this hydrogenation reaction.

Cross dehydrogenative C-O coupling catalysed by a catenane-coordinated copper(i)

Catalytic activity of copper(i) complexes supported by phenanthroline-containing catenane ligands towards a new C(sp(3))-O dehydrogenative cross-coupling of phenols and bromodicarbonyls is reported. As the phenanthrolines are interlocked by the strong and flexible mechanical bond in the catenane, the active catalyst with an open copper coordination site can be revealed only transiently and the stable, coordinatively saturated Cu(i) pre-catalyst is quickly regenerated after substrate transformation. Compared with a control Cu(i) complex supported by non-interlocked phenanthrolines, the catenane-supported Cu(i) is highly efficient with a broad substrate scope, and can be applied in gram-scale transformations without a significant loss of the catalytic activity. This work demonstrates the advantages of the catenane ligands that provide a dynamic and responsive copper coordination sphere, highlighting the potential of the mechanical bond as a design element in transition metal catalyst development.

Ultra-deep oxidative desulfurization of real fuels by sandwich-type polyoxometalate immobilized on copper ferrite nanoparticles, Fe6W18O70 subset of CuFe2O4, as an efficient heterogeneous nanocatalyst

In order to obtain the clean gasoline, we report on the synthesis and characterization of a new heterogeneous nanocatalyst comprised of the sandwich-type polyoxotungstate [(FeW9O34)(2)Fe-4(H2O)(2)](-10) (Fe6W18O70) clusters and copper ferrite (CuFe2O4) nanoparticles. The materials were characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), ultraviolet-visible (UV-vis), and scanning electron microscopy (SEM). The Fe6W18O70 subset of CuFe2O4 nanocatalyst catalyzed the oxidative desulfurization (ODS) reactions of hazardous sulfur-containing compounds by H2O2-CH3COOH as oxidant. The nanocatalyst exhibited an exceptionally high catalytic performance in the ultra-deep ODS of simulated fuels and real gasoline. The experimental results revealed that the oxidation reaction efficiencies were up to 95% at the temperature of 35 degrees C and the contact time of 1 h. Particularly, the removal (%) of thiophene (C4H4S), benzothiophene (C8H6S), and dibenzothiophene (C12H8S) from simulated fuels over Fe6W18O70 subset of CuFe2O4 nanocatalyst could reach 98%, 99%, and 99%, respectively. Moreover, the heterogeneous nanocatalyst could be easily recovered and reused multiple times by filtration with no obvious loss of activity. The present study will lead to the widespread catalytic application of Fe6W18O70 subset of CuFe2O4 material in the efficient and feasible ODS of petroleum fractions.

Zn-CNTs-Cu catalytic in-situ generation of H2O2 for efficient catalytic wet peroxide oxidation of high-concentration 4-chlorophenol

4-chlorophenol (4-CP) with high concentration is difficult to degrade thoroughly by traditional treatment methods due to its high biotoxicity and refractory to bio-degradation. A novel catalytic we peroxide oxidation (CWPO) system based on Zn-CNTs-Cu catalysts through the in-situ generation of H2O2 was constructed and investigated for the degradation of high-concentration 4-CP for the first time. Zn-CNTs-Cu composite was prepared by the infiltration melting-chemical replacement method. The operational factors effect, mechanism, and pathways of Zn-CNTs-Cu/O-2 system for high concentration of 4-CP degradation were systematically performed and discussed. At the optimal experimental conditions, the degradation efficiency of 4-CP through CWPO system with Zn-CNTs-Cu/O-2 achieved 100 %, which was 689 % higher than that of we oxidation system with O-2 alone. According to the mainly in-situ generated H2O2, the strong oxidative O’H radical and wet-oxidation effect of O-2, high concentration of 4-CP degraded into small molecular organic matter, even been mineralized into carbon dioxide and water in the Zn-CNTs-Cu/O-2 based CWPO system. Overall, Zn-CNTs-Cu/O-2 CWPO system can efficiently degrade high-concentration 4-CP through the in-situ generation of H2O2 without extra replenishment, and it provides a novel method and strategy to the efficient treatment of refractory chlorophenols wastewater.

Copper(II) Schiff Base Complex with Electrocatalytic Activity Towards the Oxygen Reduction Reaction and Its Catalase Activity

The fuel cell is a continuously operating, low environmental impact, highly energy-efficient electrochemical device that has been cited as a clean energy source to replace fossil fuels. However, noble metals, such as platinum, are used as electrocatalysts to improve reaction kinetics, which raises the cost of this renewable energy source. This work aimed to evaluate a graphite paste electrode, modified with a copper(II) coordination compound containing N,O-donor groups, as an electrocatalyst in oxygen reduction reactions (ORR) and its catalase-like activity. Through electrochemical analyses, such as cyclic voltammetry and chronoamperometry, the modified electrode activity was investigated at different pH values and scan rates. Catalase activity was also investigated at different pH values in order to establish which would be the most active. The modified electrode proved to be a promising electrocatalyst in ORR in alkaline medium, and the copper(II) complex actively degraded hydrogen peroxide under alkaline conditions, which can help to increase the lifetime of the fuel cell device.

Inverse CeO2/CuO WGS catalysts: Influence of the presence of oxygen in the reactant mixture

Three catalysts based on inverse configuration of copper-ceria catalysts, i.e. CeO2/CuO and two others in which the copper oxide phase is doped with Mn and Zn, respectively, are examined with respect to their performance for the water-gas shift reaction (WGS) and the influence of oxygen and/or hydrogen presence in the reaction mixture. Multitechnique characterization of the catalysts evidence the inverse configuration of the catalysts prepared by microemulsion method, which are basically constituted by small ceria particles of 4-5 nm supported onto larger copper oxide particles of 12-20 nm. Doping with Mn or Zn enhances the WGS performance of the catalyst. The presence of small amounts of oxygen in the reaction mixture importantly enhances the CO conversion as a consequence of the competing CO oxidation reaction. However, oxygen promotion of the WGS activity is only observed for the undoped catalyst at relatively low temperature and high CO/O-2 ratio. The catalysts display high CO conversion levels even in the presence of hydrogen and oxygen, suggesting the feasibility of carrying out WGS and CO-PROX in a single step using them.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 14347-78-5, you can contact me at any time and look forward to more communication. Safety of (R)-(2,2-Dimethyl-1,3-dioxolan-4-yl)methanol.
