Novel Green Method for the Synthesis of Monoacetin over Bifunctional Cu-Cr Phosphates under the CO2 Atmosphere

Monoacetin was synthesized using a novel green method in which acetonitrile was hydrolyzed and then esterified with glycerol over Cu-Cr phosphates under the CO2 atmosphere. Monoacetin was synthesized with high yield (87.6% glycerol conversion and 86.3% monoacetin selectivity) through this one-pot cascade method. In this process, acetonitrile can react with water to form acetamide and further undergo esterification with glycerol. There are two main reasons for obtaining monoacetin in high yield: (1) the interaction of CO, with high-temperature liquid water enhances the acid strength of the reaction system and then promotes the activation of acetonitrile; and (2) the introduction of Cr species causes a synergistic effect between Cu and Cr species to adjust the acidity and basicity of the catalyst. The introduction of Cr species converts eight-coordinated Cu2+ into four-coordinated Cu2+ to improve the acidity of the catalyst. The introduction of Cr species also causes the surface oxygen to be transformed into lattice oxygen to enhance the basicity of the catalyst. These bimetallic phosphate materials may provide a new pathway for the application of acid-base bifunctional catalytic reactions.

Pd@CeO2-catalyzed cyanation of aryl iodides with K4Fe(CN)(6)center dot 3H(2)O under visible light irradiation

Cyanation of aryl iodides is still challenging work for chemical researchers because of harsh reaction conditions and toxic cyanide sources. Herein, we have developed a new protocol based on the combination of the catalyst Pd@CeO2, nontoxic cyanide source K-4[Fe (CN)(6)]center dot 3H(2)O, and driving force visible light irradiation. The reaction is operated at relatively moderate temperature (55 degrees C) and exhibits good catalytic efficiency of product aryl nitriles (yields of 89.4%). Moreover, the catalyst Pd@CeO2 possesses good reusability with a slight loss of photocatalytic activity after five consecutive runs. The reaction system based on the above combination shows a wide range of functional group tolerance under the same conditions. Reaction conditions such as temperature, time, the component of catalyst, and solutions are optimized by studying cyanation of 1-iodo-4-nitrobenzene as model reaction. According to these results, the possible mechanism of Pd@CeO2-catalyzed cyanation of aryl iodides under visible light irradiation is proposed based on the influence of visible light on the catalyst and reactant compounds. In all, we provided an environmental and economic method for preparation of aryl nitriles from cyanation of aryl iodides based on the goal of green chemistry for sustainable development.

Novel 3D Pd-Cu(OH)(2)/CF cathode for rapid reduction of nitrate-N and simultaneous total nitrogen removal from wastewater

Removal of NO3- is a challenging problem in wastewater treatment. Electrocatalysis shows a great potential to remove NO3- but selectively converting NO3- to N-2 is facing a low efficiency. Here, a novel 3D Pd-Cu(OH)(2)/CF cathode based electrocatalytic (EC) system was proposed that can rapidly and selectively convert NO3- to NH4′, and further convert to N-2 simultaneously. The special designs for the system include: Cu(OH)2 nanowires were firstly grown on copper foam (CF) with excellent conductivity that features high specific surface area in enhancing NO3- absorption and conversion to NO2-. Then, palladium (Pd) with a superior photons activation capacity was doped on the Cu(OH)(2) nanowires to promote the reduction of NO2- to NH4. Then NH4 was quickly oxidized into N-2 by active chlorine. Finally, total nitrogen (TN) could easily be removed completely via above exhaustive cycle reactions. The 3D Pd-Cu(OH)(2)/CF cathode exhibits a 98.8 % conversion of NO3- to NH4 in 45 min with the reported highest removal rate of 0.017 cm(-2) min’, which is 19.4 times higher than that of CF. The converted NH4+ was finally exhaustively oxidized to N-2 with a 98.7 % of TN removal in 60 min.

Theoretical computation of the electrocatalytic performance of CO2 reduction and hydrogen evolution reactions on graphdiyne monolayer supported precise number of copper atoms

CO2 reduction (CO2RR) and hydrogen evolution reactions (HER) are widely used in advanced energy conversion systems, which are urgently required low-cost and high efficient electrocatalysts to overcome the sluggish reaction kinetic and ultralow selectivity. Here, the single-, double-, and triple-atomic Cu embedded graphdiyne (Cu1-3@GDY) complexes have been systematically modeled by first-principles computations to evaluate the corresponding electric structures and catalytic performance. The results revealed that these Cu-1-(3)@GDY monolayers possess high thermal stability by forming the firm Cu-C bonds. The Cu-1-(3)@GDY complexes exhibit good electrical conductivity, which could promote the charge transfer in the electroreduction process. The electronic and magnetic interactions between key species (*H, *COOH, and *OCHO) and Cu1-3@GDY complexes are responsible for the different catalytic performance of HER and CO2RR on different Cu-1-(3)@GDY sheets. The Cu-2@GDY complex could efficiently convert CO2 to CH4 with a rather low limiting potential of -0.42 V due to the spin magnetism of catalysts. The Cu-1@CDY and CuAGDY exhibit excellent HER catalytic performance, and their limiting potentials are -0.18 and -0.02 V, respectively. Our findings not only provide a valuable avenue for the design of atomic metal catalysts toward various catalytic reactions but also highlight an important role of spin magnetism in electrocatalysts.

A novel hydrometallurgical treatment for the recovery of copper, zinc, lead and silver from bulk concentrates

Nowadays sulphide ores exploitation is undergoing some troubles, which are hindering the treatment through traditional routes. Bulk flotation followed by a novel hydrometallurgical process can dodge these difficulties. In this work, an integral hydrometallurgical process consists of two ferric leaching steps, followed by a hot brine leaching stage, is proposed to recover target metals from a bulk sulphide concentrate (2.9% Cu, 7.4% Zn, 2.5% Pb, 67 ppm Ag and 37.2% Fe). In the first ferric leaching step, sphalerite, galena and copper secondary sulphides are dissolved and, in the second leaching step, a silver salt is added in order to catalyse chalcopyrite oxidation. If silver salt is added at the beginning of the process, sphalerite passivation is observed, and therefore zinc recovery is not possible. However, when catalytic leaching is performed after a previous ferric leaching, copper and zinc recoveries higher than 95% are achieved. The leached concentrate (0.3% Cu, 0.8% Zn, 3.3% Pb, 1438 ppm Ag, 38.0% Fe and 6.6% S-0), is treated by a hot brine leaching. When hot brine leaching is performed at high pulp density, elemental sulphur removal is necessary to recover all silver added as a catalyst. Extractions higher than 95% for Zn, Cu and Pb are achieved as well as the total recovery of catalyst. The proposed process is silver surplus; therefore, this agent can be recirculated.

Synthesis and field emission properties of Cu-filled vertically aligned carbon nanotubes

A highly conductive metal core modifies the electronic properties of a carbon shell, offering the possibility of enhancing its field emission (FE) behavior. Herein, a method has been devised to synthesize copper-filled vertically aligned carbon nanotubes (Cu@VACNTs) directly on Cu disks without extra metal catalysts via plasmaenhanced chemical vapor deposition. An ensemble of Cu particles formed on the surface of Cu disks due to surface reconstruction in a reducing environment plays a crucial role in the nucleation and growth of Cu@ VACNTs. The filling of Cu inside the VACNTs can be controlled by tuning the growth temperature. The study of FE properties revealed that a conductive Cu-core extending throughout the entire length of the VACNTs could significantly enhance the FE properties of the VACNTs. Excellent FE properties including low turn-on field (E-TO = 1.57 V/mu m), low threshold field (E-Th = 2.43 V/mu m), high field enhancement factor (beta = 3061), and high FE stability were observed for the Cu@VACNTs. The enhanced FE properties of the Cu@VACNTs can be accredited to low field screening due to bundled morphology and improved electrical and thermal conductivities offered by the encapsulation of highly conductive Cu nanowires inside the cores of VACNTs.

Ethanol dimerization to Ethyl acetate and hydrogen on the multifaceted copper catalysts

Ethanol dimerization to form ethyl acetat(e) and hydrogen (EDEH) is the best atomically economic reaction and has also been considered as an environmentally friendly process in ethyl acetate synthesis. Understanding of the catalytic activities for the EDEH while preventing byproduct formation is essential to achieve the total utilization of atoms truly. We performed density functional theory calculations to investigate the EDEH on Cu in the presence of three surfaces, namely Cu(111), Cu(110), and Cu(100). The results show that the rate-limiting step of the EDEH is surface-dependent but temperature-independent at reactions lower than 800 K. The rate-limiting step on Cu(110) is the CH3CHO dehydrogenation to CH3CO, whereas that of Cu(111) and Cu(100) is the ethanol dehydrogenation to CH3CH2O. In the presence of all three surfaces, the EDEH takes place mostly on both Cu (110) and Cu(100), with the rate-limiting step being the dehydrogenation of ethanol to CH3CH2O on Cu(110). We further analyzed the electronic properties of surface Cu atoms and decoupled the electronic and geometric effects. The results indicate that the electronic effect plays a critical role in the three dehydrogenation reactions, whereas the geometric effect mainly affects the C-O and H-H couplings.

The effect of CuO on a Pt-Based catalyst for oxidation in a low-temperature fuel cell

Electrocatalytic oxidation of methanol, ethanol, and formic acid has currently attracted research attention for low-temperature fuel cells. However, the efficiencies of these fuel cells mainly depend on the electrocatalytic activities of Pt-based anodic catalysts due to the problems of low kinetics for small organic molecule electro-oxidation. An anode catalyst can be developed by the addition of some metal oxides into a Pt-based catalyst, which can effectively promote the electro-oxidation of fuels based on small organic molecules. In this work, a nanocomposite catalyst consisting of multi-wall carbon nanotubes (CNTs), copper oxide (CuO) and Pt nanoparticles was synthesized and used to improve fuel cell oxidation. Due to its low cost and oxophilic character, the metal oxide can play a major role in the oxidation of CO. The synthesis of xPt-yCuO/CNT electrocatalysts was executed through two steps: supporting of CuO nanoparticles on CNTs by the alcothermal method followed by Pt loading onto the prepared CuO/CNT by chemical reduction. The as-prepared catalysts were physically characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Raman spectroscopy, and electrochemical measurements. The results demonstrate that CuO is well dispersed onto the CNTs and that this oxide can further interact with the active Pt present on the as-prepared catalyst composites. The activity of various xPt-yCuO/CNT electrocatalysts was determined by cyclic voltammetry (CV), where x and y are the mass ratios of Pt and CuO, respectively. The presence of CuO was found to significantly contribute to enhanced electroactivity towards oxidation reactions. The 1Pt-3CuO/CNT electrocatalyst is a capable catalyst for improving low-temperature fuel cell applications. (c) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.

Catalytic Oxidation of Trypan Blue Using Copper Complexes and Hydrogen Peroxide Shows a Negative Reaction Order

In most chemical reactions, reaction rates increase with increasing reactant concentrations. In this study, we report an unusual catalytic oxidation reaction with a negative reaction order, in which the reactant concentration inversely affected the oxidation rate. In the reaction, trypan blue was oxidized by hydrogen peroxide with copper-triglycine as a catalyst. Under a strong alkaline condition, the reaction rate was inversely proportional to the hydrogen peroxide concentration (i.e., the reaction rate was faster when the hydrogen peroxide concentration was lower). Without the copper-triglycine catalyst, the phenomenon did not happen. A possible explanation was that hydrogen peroxide competed with the reactive species of the catalyst and slowed down the reaction. This phenomenon had an important implication in advanced oxidation processes for wastewater treatments. To achieve a faster oxidation rate of trypan blue, one should add hydrogen peroxide slowly to keep its concentration low at all times. On the basis of this principle, we developed a continuous microdroplet injection process to deliver the hydrogen peroxide solution as droplets. This process was faster and more efficient than a batch process for the degradation of trypan blue.
