Microwave synthesis of beta-Cu2V2O7 nanorods: structural, electrochemical supercapacitance, and photocatalytic properties

Nanostructured metal vanadates have recently harvested enormous consideration among the researchers due to their remarkable performances in catalysis, electronic devices, energy storage, and conversion. In the present work, we have formulated a facile and template-free method to synthesize beta-Cu2V2O7 nanorods and analyzed their characteristics by using various spectroscopy techniques. Copper and vanadium are the earth abundant, relevantly economical, and possess several oxidation states, which can render a broad range of redox reactions favorable for the electrochemical performance. The catalytic efficiency of the synthesized nanomaterial was assessed by the photocatalytic degradation of methylene blue (MB) as a model cationic dye under the visible light irradiation. At the irradiation time of 60 min, the catalyst showed the degradation efficiency of 81.85%, k(app) (min(- 1)) of 0.0193 min(-1) with the first-order kinetic model reaction. The electrochemical measurements were performed using a three-electrode configuration in 1M NaOH solution. The measured specific capacitance of Cu2V2O7 modified electrode was 269 F/g at 1 A/g with good stability and retention capacity of 89% after 4000 cycles that paved the way to consider beta-Cu2V2O7 as prospective material for energy-storage applications.

Green synthesis of heterogeneous copper-alumina catalyst for selective hydrogenation of pure and biomass-derived 5-hydroxymethylfurfural to 2,5-bis(hydroxymethyl)furan

In this work novel copper-alumina catalysts were prepared through a solvent-free solid-state grinding method – a low cost and green catalyst preparation method for selective hydrogenation of 5-hydroxymethylfurfural (5-HMF) into 2,5-bis(hydroxymethyl)furan (BHMF). Under the optimized reaction conditions (3 MPa H-2, 130 degrees C, 1 h), >99 % 5-HMF conversion and 93 % BHMF yield were obtained by using a 20CA (20 mol%Cu-Al2O3) catalyst. The catalyst characterization results could reveal that the high catalytic activity and selectivity could be attributed to the presence of both metallic and electrophilic copper (Cu degrees/Cu2+) species and the uniformly distributed copper nanoparticles. Furthermore, an integrated catalytic process was demonstrated for the first time for direct con version of mono, di, and polysaccharides into the corresponding BHMF, obtained overall BHMF yield in the range of 25 %-48 %.

Three-Dimensional Carbon Electrocatalysts for CO2 or CO Reduction

A challenge in the electrochemical CO(2 )reduction reaction (CO2RR) is the lack of efficient and selective electrocatalysts to valuable chemicals. Hydrocarbons and valuable chemicals from the CO2RR have primarily been observed on metallic Cu. Here, 3D carbon electrocatalysts (diporphyrin molecules; i.e., Pacman) have been investigated as potential CO2RR electrocatalysts using density functional theory simulations. This work presents a molecular-level engineering strategy for the development of electrocatalysts toward hydro-carbons. The introduction of a second metal center in the diporphyrins on one hand serves as a proton transfer or CO adsorption site, providing the possibility for the formation of C-H and C-C bonds. On the other hand, the second metal center selectively stabilizes key intermediates like *CH2O, *OCH3, and *OCCHOH, leading to CH4 and C-2 species production. It has been found that Pacman (Pac) with Mn or Fe is able to produce CH4. Furthermore, Pac-CoNi, Pac-CoCu, and Pac-CoCo with pyridine coordination catalysts generate CH3OH, while Pac-CoCo might enable C-C coupling, forming C-2 species.

Enhanced adsorption/photocatalytic removal of Cu(II) from wastewater by a novel magnetic chitosan@ bismuth tungstate coated by silver (MCTS-Ag/Bi2WO6) composite

An easily separation composite, magnetic chitosan@bismuth tungstate coated by silver (MCTS-Ag/ Bi2WO6), was successfully synthesized by the simple hydrothermal method. Moreover, the MCTS-Ag/ Bi2WO6 demonstrated excellent adsorption/photocatalytic removal of Cu(II) in aqueous solution. Adsorption played a leading role in the synergistic reaction. The catalysts were characterized by fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and scanning electron microscope (SEM). The effects on adsorption of Cu(II) were investigated, which included illumination, pH, and initial concentration. The experimental results showed that the theoretical maximum adsorption capacity of Cu(II) (181.8 mg/g) was achieved under simulated solar light irradiation with the optimal pH value of 6.0, indicating that illumination could enhance the adsorption of Cu(II) by MCTS-Ag/Bi2WO6. Meanwhile, the composite exhibited desirable adsorption ability of Cu(II) after 5 cycles. The copper ion adsorption fitted well with pseudo-second-order kinetic model and its isotherm followed Freundlich model. (C) 2020 Elsevier Ltd. All rights reserved.

On the interpretation of X-ray photoelectron spectra of Pt-Cu bimetallic alloys

The progress in the design of a perspective alloy catalyst relies on correct interpretation of its photoelectron spectra. Particularly, X-ray photoelectron spectroscopic (XPS) analysis of platinum-copper alloys represents a serious challenge for both qualitative and quantitative analyses due to the complexity of the Pt 4f spectra arising from its overlapping with the Cu 3p region. Studies regarding XPS investigation of Pt-Cu alloys often ignore the Cu 3p contribution while fitting Pt 4f spectra, which leads to partially incorrect interpretation of measured XPS data. This is most noticeable for alloys containing more than 50 % of platinum where the low-intensity Cu 3p core levels can be hidden under a more intense contribution of Pt 4f. In this work, we present the correct way of processing photoemission spectra of such systems. First, we thoroughly examine the XPS Cu 3p spectra of pure copper surfaces of different oxidation states, namely Cu degrees, Cu+, and Cu2+. Then, the obtained results are applied for the fitting of Pt 4f spectra of both metallic and oxidized Pt-Cu systems. The precise curve-fitting and data analysis procedure showcased in this study can be utilized to eliminate uncertainties in the analysis of Pt-Cu photoemission spectra.

Navigating Copper-Atom-Pair Structural Effect inside a Porous Organic Polymer Cavity for Selective Hydrogenation of Biomass-Derived 5-Hydroxymethylfurfural

In recent times, selective hydrogenation of biomass-derived 5-hydroxymethylfurfural (5-HMF) to produce the novel difuranic polyol scaffold 2,5-dihydroxymethylfuran (DHMF) has attracted the interest of the many researchers due to its peculiar symmetrical structure and its widespread application as a monomer for the preparation of cross-linked polyesters and polyurethane. Copper-based catalysts have been explored for selective catalytic hydrogenation; however, hurdles are still associated with the strongly reducing H-2 atmosphere and oxidizing C-O bond that make the Cu-0 and Cux+ surface active species unstable, limiting the rational design of highly efficient integrated catalyst systems. To address this, herein, we built catalytic systems for S-HMF hydrogenation with stable and balanced Cu-0 and Cux+ active surface species inside the nanocage of a catechol-based porous organic polymer (POP) endowed with large surface areas, impressive stabilities, and spatial restriction inhibiting nanoparticle aggregation. Batch reactor screening identified that a superior catalytic performance (DHMF selectivity of 98%) has been achieved with our newly designed Cu@C-POP at 150 degrees C temperature and 20 bar H-2 pressure, which was also higher than that of other reported copper catalysts. Comprehensive characterization understanding with H-2 -TPR and X-ray photoelectron spectroscopy (XPS) study revealed that substantially boosted activity is induced by the presence of the bulk CuOx phase and atomically dispersed Cu species incorporating isolated Cu ions, which are further confirmed through the positive binding energy shift of Cu 2p(3/2) XPS spectra (similar to 0.4 eV). The Cu environment in our catalytic systems comprises a predominantly square planar geometry (probably Jahn-Teller distorted OH), which we gleaned from the extended X-ray absorption for fine structure (EXAFS) analysis featuring two adjacent copper atoms with the valence state in between of 0 and +2, as validated by XANES absorption edge positions. EXAFS studies further revealed a lowering of the Cu coordination number for the most active Cu@C-POP-B catalyst, suggesting the presence of metal vacancies. Density functional theory calculations showed that the presence of Cu metal vacancies stabilized the reaction intermediates formed during 5-HMF hydrogenation and decreased the hydrogenation barriers, resulting in an enhanced catalytic activity of the Cu@C-POP-B catalyst.

Copper(I) Complex of Dihydro Bis(2-Mercapto Benzimidazolyl) Borate as an Efficient Homogeneous Catalyst for the Synthesis of 2H-Indazoles and 5-Substituted 1H-Tetrazoles

In this work, catalytic activity of a series of copper(I) complexes containing dihydrobis(2-mercapto-benzimidazolyl) borate (Bb), and phosphine co-ligands was investigated in the synthesis of N-heterocycle compounds including 2H-indazoles and 5-substituted 1H-tetrazoles. The copper(I) complex containing tricyclohexylphosphine co-ligand, [Cu(Bb)(PCy3)], displayed the highest catalytic activities for the formation of 2H-indazoles and 1H-tetrazoles. Apart from the nontoxicity and strong sigma-donating ability of the introduced ligands, the introduced catalyst required easy handling processes. The catalytic reactions were successfully performed at low catalyst loadings in either PEG-200 or DMF and in relatively short reaction times. The diversity of these reactions was also explored with 20 and 12 examples. Finally, the current catalytic system is amenable to large-scale production of these N-heterocycle compounds.

Hydrometallurgical Recovery of Cu and Zn from a Complex Sulfide Mineral by Fe3+/H2SO4 Leaching in the Presence of Carbon-Based Materials

Chalcopyrite, the main ore of copper, is refractory in sulfuric media with slow dissolution. The most commonly employed hydrometallurgical process for the oxidation of chalcopyrite and copper extraction is the sulfuric acid ferric sulfate system The main objective of the present work is to study the use of cheap carbon-based materials in the leaching of copper and zinc from a sulfide complex mineral from Iberian Pyrite Belt (IPB). The addition effect of commercial charcoal (VC) and two magnetic biochars (BM and HM) that were obtained by pyrolysis of biomass wastes was compared to that of commercial activated carbon (AC). The experimental results performed in this work have shown that the presence of carbon-based materials significantly influences the kinetics of chalcopyrite leaching in the sulfuric acid ferric sulfate media at 90 degrees C. The amount of copper and zinc extracted from IPB without the addition of carbon-based material was 63 and 72%, respectively. The highest amount of extracted zinc (>90%) was obtained with the addition of VC and AC in IPB/carbon-based material ratio of 1/0.25 w/w. Moreover, it is possible to recover more than 80% of copper with the addition of VC in a ratio 1/0.25 w/w. Moreover, an optimization of the properties of the carbon-based material for its potential application as catalyst in the leaching of metals from sulfide is necessary.
