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.

Shape and Surface Morphology of Copper Nanoparticles under CO2 Hydrogenation Conditions from First Principles

Predicting the state of Cu under a broad range of reaction conditions (pressure and temperature with various adsorbates: CO2, CO, H2O, H*, and O*) is an important property to understand CO2 hydrogenation catalysts. Here, unsupported copper (Cu) nanoparticles (NPs) were modeled in vacuum and under conditions relevant for CO2 hydrogenation conditions from first principles using density functional theory calculations; such models allow precise prediction of particle shapes and surface coverage of the relevant facets of Cu NPs over a large range of conditions relevant to CO2 hydrogenation. This model predicts that the Cu surfaces are fully reduced (in line with experimental results) and free of adsorbed oxygen (O*), H2O*, and CO2* under typical reaction conditions. Furthermore, the Cu(111) facet is at least partially covered with hydrogen (H*) and the Cu(110) facet is partially covered with adsorbed CO* at high reverse-water-gas-shift (RWGS) conversions, while the Cu(100) and Cu(211) facet remain adsorbate-free. Overall, the particle shape of Cu NPs under CO2 hydrogenation conditions is dominated by the (111) facet with a small area of the (100) facet being present (among all the facets considered). The final equilibrium particle shape is set during the initialization of the CO2 hydrogenation reaction and does not change even when the WGS equilibrium is reached.

Recent Advances in Microwave-Assisted Copper-Catalyzed Cross-Coupling Reactions

Cross-coupling reactions furnishing carbon-carbon (C-C) and carbon-heteroatom (C-X) bond is one of the most challenging tasks in organic syntheses. The early developed reaction protocols by Ullmann, Ullman-Goldberg, Cadiot-Chodkiewicz, Castro-Stephens, and Corey-House, utilizing elemental copper or its salts as catalyst have, for decades, attracted and inspired scientists. However, these reactions were suffering from the range of functional groups tolerated as well as severely restricted by the harsh reaction conditions often required high temperatures (150-200 degrees C) for extended reaction time. Enormous efforts have been paid to develop and achieve more sustainable reaction conditions by applying the microwave irradiation. The use of controlled microwave heating dramatically reduces the time required and therefore resulting in increase in the yield as well as the efficiency of the reaction. This review is mainly focuses on the recent advances and applications of copper catalyzed cross-coupling generation of carbon-carbon and carbon-heteroatom bond under microwave technology.

Enhanced catalytic performance in low-temperature NH3-SCR process of spherical MCM-41 modified with Cu by template ion-exchange and ammonia treatment

Spherical MCM-41 (S-MCM-41) was synthesised and used as support for deposition of copper by template ionexchange (TIE) method using CuCl2 solutions. Another series of catalysts was prepared by modified TIE procedure, including treatment of S-MCM-41, directly after TIE, with ammonia solution (TIE-NH3). The samples were characterized with respect to chemical composition (ICP-OES), texture (N-2 -sorption), structure (XRD, FTIR), morphology and surface composition (SEM-EDS), aggregation of copper species (UV-vis-DRS), reducibility (H-2-TPR) and surface acidity (NH3-TPD). It was shown that deposition of copper by TIE method resulted in samples containing simultaneously highly dispersed copper species as well as CuO nanorods. The TIE-NH3 procedure resulted in deposition of highly dispersed copper species located mainly inside pores without formation of CuO crystallites. The samples obtained by TIE-NH3 method were found to be very promising catalysts for the low-temperature NH3-SCR process, possibly due to the presence of large number of highly dispersed copper species, deposited on the large surface area of S-MCM-41.

Reactivity of styrene with tert-butyl hydroperoxide over cu-based double hydroxide catalysts

Copper(II) ions are inserted into brucite-like sheets in the Zn-Cu-Al ternary hydroxides via the precipitation route. The amount of octahedral Cu(II) sites in the Zn-Al(OH) interlayers depends on the copper loadings. The square-planar configuration (CuO) was observed in the high-copper content samples. The Cu-inserted zinc aluminum hydroxides have lamellar structure, modest surface area, and hexagonally uniform plate-like particles. All synthesized hydroxides were tested for the liquid-phase oxidation of styrene. The overall conversion of styrene obtained about 60-80 % and styrene oxide selectivity is about 70 %. The catalytic activity is correlated with the electronic configurations of copper(II) ions and reaction variables. The copper(II) ions in the brucite-like sheets proceeded through the oxidation of styrene following the metal-superpoxo pathway while the extra-lattice copper(II) ions underwent reaction with free radical route. The experimental results also indicated Cu-intercalated layered double hydroxide catalysts are more active than copper(II) oxide in the liquid-phase oxidation of styrene under the same conditions.

Catalytic effect and mechanism of coexisting copper on conversion of organics during pyrolysis of waste printed circuit boards

Pyrolysis is a promising technology for recycling organic materials from waste printed circuit boards (WPCBs). Nevertheless, the generated organic bromides are toxic and urgently needed to be removed. The coexisting copper (Cu) of WPCBs has potential performance on debromination. However, the catalytic effect and mechanism of Cu on pyrolysis process and products were still unclear. To clarify the in-situ catalysis of Cu, the analysis on kinetics and pyrolysis products was performed. The results showed that Cu can change the mechanism function of pyrolysis, which reduced the apparent activation energy (Ea). The mechanism function of Cu-coated WPCBs was obtained by Sestak-Berggren model and expressed as: d alpha/dt = 1.65 x 10(7) x [(1 – alpha)(-1.30)-alpha(6.09)(ln(1 alpha))(-6.03)]exp(- 202.45KJ/mol/RT).Product analysis suggested that Cu proRT moted the conversion of organic bromides to Br-2 and HBr. During the process of pyrolysis, bromide atoms interacted with Cu to form coordination compound, which can weaken the strength of C-Br bond and generate bromide free radical (Br*). Besides, Cu can promote the conversion of aromatic-Br to Br-2 as the catalyst for Ullmann cross-coupling reaction. Therefore, the presence of Cu was beneficial to pyrolysis. This work provided the theoretical basis for the improvement and application of pyrolysis technology.

Promotion of electrochemical CO2 reduction to ethylene on phosphorus-doped copper nanocrystals with stable Cu delta+ sites

Electrochemical reduction of CO2 to C2+ products is a sustainable energy-driven pursuit for high added-value hydrocarbons. Tremendous efforts have been made to copper based electrocatalysts, which are well-known for producing C2+ products. However, being short of well-defined catalysts with stable Cu delta+ electronic structure hinders its practical application and in-depth understanding. Herein, we developed a facile one-pot approach to prepare Cu delta+ -rich catalyst by doping phosphorus. Enhanced performance and tunable product selectivities are achieved due to the electron donor-acceptor interaction based on phosphorus content in series. C-2 hydrocarbons and alcohols are produced with high (similar to 44.9%) selectivity, in which C2H4 (30.7 +/- 0.9%) is dominant at -1.6 V vs reversible hydrogen electrode (RHE). This P-Cu catalyst shows a significantly higher current density (57.2 mA cm(-2) ) compared to pristine Cu. In addition, the favorable Cu delta+ is reserved during CO2RR contributing to a longterm stability. Experimental results and DFT calculations demonstrate that the Cu delta+ moiety facilitates the adsorption of carbon intermediates, C-C coupling and hence promotes the generation of C2H4 energetically. The well-designed catalyst indicates the profit of electronic structure engineering in designing catalysts for multiplestep chemical conversions.

High-selectivity electrochemical CO2 reduction to formate at low overpotential over Bi catalyst with hexagonal sheet structure

The electrochemical conversion of CO2 to formate still suffers from poor selectivity, low production rate, and high overpotential. In this study, a facile strategy is developed to obtain Bi catalysts with a hexagonal sheet structure on copper foil via the constant potential electrodeposition method. The electrocatalyst shows high activity for formate production from CO2 reduction, with the formate faradaic efficiency (FE) reaching nearly 100% at an overpotential of 0.65 V; a high production rate of 96.37 mu mol. h(-1) mm(-2) is obtained, and the corresponding power consumption is as low as 3.64 kW.h.kg(-1). The excellent catalytic ability is derived from the sharp edges and corner sites of the catalyst, as they provide numerous surface-active sites and increase the electrical conductivity and local electric field intensities of the surface electrode; thus, the electrochemically active surface area (ECSA) and the electron-donating ability of the Bi electrode are enhanced, while the competing hydrogen evolution reaction (HER) is significantly inhibited. Moreover, the Bi sheets show excellent stability in 24 h electrolysis, with a formate FE of >= 95.8% in aqueous 0.1 M KHCO3 solution. This work indicates that structural adjustment is a critical factor in enhancing the electrocatalytic performance of metallic Bi.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 16606-55-6, you can contact me at any time and look forward to more communication. Formula: C4H6O3.
