Investigation of eATRP for a Carboxylic-Acid-Functionalized Ionic Liquid Monomer

Electrochemically mediated atom transfer radical polymerization (eATRP) is a promising technique for precise control over polymer molecular weights (MWs), molecular weight distribution (D), and complex architectures under low concentrations of copper-based ATRP catalysts. Herein, eATRP of ionic liquid monomer (ILM), 1-vinyl-3-propionate imidazolium tetrafluoroborate (VPI+BF4-), containing carboxylic acid groups is inquired in aqueous media. In the polymerization process of water-soluble VPI+BF4-, the protonation and dissociation of catalysts have great influence on the polymerization reaction. Various polymerization parameters, including applied potential (E-app), pH, degree of polymerization (DP) (from 100 to 300), and the catalyst concentration (from 5 x 10(-4) to 1.5 x 10(-3) m) are examined. Under certain polymerization conditions, poly(ionic liquids) (PILs) with a well-controlled MWs and narrow D are obtained. The controlled/living property of the polymerization process is reflected by the linear first-order kinetics, linear increase of MWs with monomer conversion, and the probability of complete reactivation of the polymerization by repetitively altering the E-app values. This work provides a new perspective for the precise synthesis of PIL-based block copolymers with adjustable properties; meanwhile, the eATRP of monomer containing carboxylic acid groups is expected to develop functional materials with pH responsiveness and biocompatibility.

Liquid-phase oxidation of olefins with rare hydronium ion salt of dinuclear dioxido-vanadium(V) complexes and comparative catalytic studies with analogous copper complexes

Homogeneous liquid-phase oxidation of a number of aromatic and aliphatic olefins was examined using dinuclear anionic vanadium dioxido complexes [(VO2)(2)((LH)-L-sal)](-) (1) and [(VO2)(2)((LH)-L-Nsal)](-) (2) and dinuclear copper complexes [(CuCl)(2)((LH)-L-sal)](-) (3) and [(CuCl)(2)((LH)-L-Nsal)](-) (4) (reaction of carbohydrazide with salicylaldehyde and 4-diethylamino salicylaldehyde afforded Schiff-base ligands [(LH4)-L-sal] and [(LH4)-L-Nsal], respectively). Anionic vanadium and copper complexes 1, 2, 3, and 4 were isolated in the form of their hydronium ion salt, which is rare. The molecular structure of the hydronium ion salt of anionic dinuclear vanadium dioxido complex [(VO2)(2)((LH)-L-sal)](-) (1) was established through single-crystal X-ray analysis. The chemical and structural properties were studied using Fourier transform infrared (FT-IR), ultraviolet-visible (UV-Vis), H-1 and C-13 nuclear magnetic resonance (NMR), electrospray ionization mass spectrometry (ESI-MS), electron paramagnetic resonance (EPR) spectroscopy, and thermogravimetric analysis (TGA). In the presence of hydrogen peroxide, both dinuclear vanadium dioxido complexes were applied for the oxidation of a series of aromatic and aliphatic alkenes. High catalytic activity and efficiency were achieved using catalysts 1 and 2 in the oxidation of olefins. Alkenes with electron-donating groups make the oxidation processes easy. Thus, in general, aromatic olefins show better substrate conversion in comparison to the aliphatic olefins. Under optimized reaction conditions, both copper catalysts 3 and 4 fail to compete with the activity shown by their vanadium counterparts. Irrespective of olefins, metal (vanadium or copper) complexes of the ligand [(LH4)-L-sal] (I) show better substrate conversion(%) compared with the metal complexes of the ligand [(LH4)-L-Nsal] (II).

Mesoporous Carbon-supported Iron Catalyst for Fischer-Tropsch Synthesis

Mesoporous carbon materials have been employed as supports of iron-carbon complex catalysts for slurry phase Fischer-Tropsch (FT) synthesis. The mesoporous carbon-supported iron catalysts were prepared through the co-precipitation from aqueous solutions of ferrous and copper sulfates in the presence of mesoporous carbon materials synthesized through the soft-template and hard-template methods. The iron catalyst supported by the soft-templated mesoporous carbon exhibited a sharp product distribution at C5-C9 fractions (62 % in hydrocarbons) in FT synthesis at 260 degrees C under 2 MPa-G. On the other hand, the catalyst supported by the hard-templated mesoporous carbon having far larger mesopore openings showed a high selectivity to higher hydrocarbons (69 % of C10+ in hydrocarbons) with a high hydrocarbon productivity (0.74 g/g-Fe h). This catalyst also showed high catalytic activity and long lifetime up to 30 h even at lower reaction pressure of 1 MPa-G. The very large inner space of mesopores that are not easily blocked through the wax formation would be responsible for such high catalytic activity.

Degradation of Alizarin Red S by Heterogeneous Fenton-Like Oxidation Over Copper-Containing Sand Catalysts

Two new heterogeneous catalysts (Cu-sand) have been synthesized by supporting copper on the surface of natural sand using two defined methods such as chemical vapor deposition (CVD) and dry evaporation (DE). The Cu-sand catalysts were characterized by several techniques. SEM-EDX analysis indicated that 13.86 wt% of copper species were dispersed on the surface of Cu-sand (CVD) catalyst whereas 11 wt% were agglomerated on the Cu-sand (DE) surface. The presence of copper species was more noticeable in the XRD pattern for the Cu-sand (CVD) catalyst. The catalytic performance of the prepared catalysts was evaluated in the Fenton-like oxidation of Alizarin red S dye (ARS). The reactivity and stability of the two catalysts were differentiated by studying the influence of the supported amount of copper, activity of leachate and the reuse of catalyst on the conversion of initial concentration of ARS. ARS oxidation has been investigated under various experimental conditions. The best ARS conversion rate was about 95% when using Cu-sand (CVD) catalyst in optimal conditions: [H2O2](0) = 10 mmol/L, temperature = 40 degrees C and the addition of H2O2 in two stages (0 min and 20 min of treatment). CVD method makes it possible to prepare an efficient and stable catalyst.

Highly promoted hydrogen production enabled by interfacial P-N chemical bonds in copper phosphosulfide Z-scheme composite

Transition metal phosphosulfides (TMPSs) have shown great potential as efficient catalysts toward hydrogen evolution reaction (HER). To further understand and promote the catalytic activity at the phosphosulfide (PS) structures, the multifunctional role of TMPS needs to be explored. Herein, we report copper phosphosulfide (Cu3P vertical bar S) coupled with graphene-like C3N4 (GL-C3N4) as an excellent HER photocatalyst with a hydrogen production rate of 8.78 mmol g(-1) h(-1) (20.22 mmol g(-1) h(-1) with 0.5 wt.% Pt). Systematic investigations on the interaction between Cu3P vertical bar S and GL-C3N4 unveil that such impressive photocatalytic activity arises from the interfacial P-N chemical bond that constructs a Z-scheme heterostructure. Time-resolved photoluminescence analysis indicates a considerably suppressed recombination rate of photoexcited charge carriers at the interface, which facilitates electron transfer and enhances the reducibility of electrons in the conduction band of Cu3P vertical bar S. This work provides new design strategies for employing TMPSs as photocatalysts for highly efficient HER and other photoreduction reactions.

Copper ferrite anchored on hexagonal boron nitride as peroxymonosulfate activator for ciprofloxacin removal

In this study, CuFe2O4 anchored on h-BN (CuFeBN) at various %w/w ratios was prepared via a hydrothermal method and characterized. The CuFeBN catalyst consists of irregular microparticle-like morphology with uniform CuFe2O4 distribution and magnetic property. It was employed as peroxymonosulfate (PMS) activator for ciprofloxacin (CIP) removal. The results indicated that CuFeBN with CuFe2O4:h-BN w/w ratio of 1:2 (or CuFeBN-12) performed the best with CIP removal efficiency exceeding 91% in 60 min (apparent rate constant, kapp = 0.0901 min(-1)). Higher CuFe2O4:h-BN w/w ratio resulted in increased CuFe2O4 agglomeration. Additionally, increasing the CuFeBN-12 loading and initial pH leads to gradual increase in kapp due to the increased catalytic sites and catalyst-to-PMS interaction, respectively. The redox cycling between Cu(II)/Cu(I) and Fe(III)/Fe(II) resulted in the formation of SO4-, acting as the main radical for CIP degradation and mineralization. Overall, the CuFeBN-12 shows remarkable potential as PMS activator for treating antibiotics in water. (c) 2020 Elsevier B.V. All rights reserved.

With gem-difluoroalkenes and aryl iodides as the substrates, this methodology offers flexible and facile access to privileged alpha-fluorochalcones under mild reaction conditions in moderate-to-excellent yields. Mechanistic studies indicated transmetalation between palladium and copper intermediates as a crucial step of the catalytic cycle.

Transition Metal-Promoted Reactions in Aqueous Media and Biological Settings

During the last decade, there has been a tremendous interest for developing non-natural biocompatible transformations in biologically relevant media. Among the different encountered strategies, the use of transition metal complexes offers unique possibilities due to their high transformative power. However, translating the potential of metal catalysts to biological settings, including living cells or small-animal models such as mice or zebrafish, poses numerous challenges associated to their biocompatibility, and their stability and reactivity in crowded aqueous environments. Herein, we describe the most relevant advances in this direction, with a particular emphasis on the systems’ structure, their mode of action and the mechanistic bases of each transformation. Thus, the key challenges from an organometallic perspective might be more easily identified.
