Jia, Hongxing published the artcileIn situ anodic electrodeposition of two-dimensional conductive metal-organic framework@nickel foam for high-performance flexible supercapacitor, Safety of 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Journal of Power Sources (2022), 231163, database is CAplus.

Owing to their large sp. surface area and well-defined porosity, metal-organic frameworks (MOFs) have long been considered as promising materials for energy storage. Unfortunately, their straightforward utilization in supercapacitors was hindered for years due to poor conductivity until the emergence of 2D conductive MOF materials. To date, several 2D conductive MOF-based supercapacitors have been reported. Nevertheless, almost all these supercapacitors were fabricated from MOF powders through a slurry coating method or dense packing method, which neg. affected their capacitor performance. Herein, we have developed an anodic electrodeposition (AED) approach to fabricate a uniformly deposited 2D conducting MOF on nickel foam and use it directly as electrodes for supercapacitors without any additives. The superior performance of the 2D conducting MOF on nickel foam in both aqueous and organic electrolytes was then disclosed by a series of electrochem. measurements, demonstrating the significant advantages of the AED approach over traditional methods.

Li, Dandan published the artcileIntensifying the moderate electric field-induced modification of maize starch by 1-butyl-3-methylimidazolium chloride, Synthetic Route of 79917-90-1, the publication is Carbohydrate Polymers (2022), 119654, database is CAplus and MEDLINE.

This study aimed to improve the effect of moderate elec. field (MEF) treatment on the structural and physicochem. properties of maize starch by adding 1-butyl-3-methylimidazolium chloride ([bmim]Cl). Starch (20%, w/v) was mixed with [bmim]Cl solution (0, 30%, 50%, and 70%, weight/weight), and then electro-treated (5 V/cm, 50 Hz) at 60 °C for 10 min. As the [bmim]Cl concentration increased, the electro-induced disintegration of starch granules was enhanced due to the intensified Joule heat and decreased pH of reaction bulk. After electro-treated in 70% weight/weight [bmim]Cl, a transparent solution of starch was observed and the recovered starch tended to dissolve rather than swell in water. Compared with water-bath heating, MEF caused more destruction in the granular and crystal structure, increased the particle size, decreased the pasting viscosity, and reduced the gelatinization enthalpy and thermostability of starch. The obtained results could provide guidance for the application of electro-based techniques in starch modification.

Lee, Jyun-Ting published the artcileHigh-efficiency cycling piezo-degradation of organic pollutants over three liters using MoS₂ /carbon fiber piezocatalytic filter, Quality Control of 79917-90-1, the publication is Nano Energy (2022), 107280, database is CAplus.

Piezocatalysis has great potential com. application for the high-efficiency degradation of organic pollutants in a dark environment. However, the recycling of catalyst materials and the subsequent generation of secondary pollution remain challenging. In this study, MoS₂ nanoflowers (NFs)/carbon fiber was synthesized to develop a piezocatalytic filter that can recycle decomposed wastewater easily without generating secondary pollutants in treated water. The MoS₂/carbon fiber was constructed in pipelines to form the piezoelec. degradation system, which demonstrated a high efficiency in decomposing organic mols. in wastewater through natural water flow. The piezocatalytic filters in the circulatory system completely degraded a large amount of dye solution (1000 mL) in 40 min and can repeat three-times degradation with the total organic carbon value decreased by 90%. The theor. calculation indicated that MoS₂ grew on carbon fiber, which exhibited a bending moment effect under natural water-flow-induced pressure. This established considerable piezoelec. potential at MoS₂ NFs active edge sites and MoS₂-carbon fiber interfaces, triggering electron-hole pair separation under the internal elec. field. The MoS₂/carbon fiber piezoelec. catalyst is advantageous for its reusability and recyclability, thus preventing secondary pollution and adverse effects on water bodies during practical high-flux wastewater treatment.

Song, Xiangbo published the artcileA highly effective approach to enhance the performance of biomass-derived acid for fructose conversion to 5-hydroxymethylfurfural, Product Details of C8H15ClN2, the publication is Fuel Processing Technology (2022), 107318, database is CAplus.

Synthesis of 5-hydroxymethylfurfural (HMF) from carbohydrate is one of vital step for bio-refinery development. In this work, a novel strategy was developed for catalytic conversion of fructose to HMF in 2-butanol. The inexpensive ionic liquids were used to adjust the acidity of biobased acid catalyst for enhancing the dehydration of fructose to HMF. The combination of 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) with oxalic acid afforded an excellent HMF yield of 97.1% at 98.7% fructose conversion under mild conditions of 100°C and 60 min, owing to the enhanced dissociation ability of oxalic acid by [Bmim]Cl. A possible dissociation mechanism of oxalic acid induced by [Bmim]Cl was proposed based on control experiments and detailed analyses with NMR and FT-IR techniques. It involved that the [Bmim]Cl interacted with oxalic acid through hydrogen bond, which decreased the electron d. of oxygen atom on hydroxyl group and weakened the O-H bond, thus making the hydrogen in the O-H group to easily dissociate in the form of H⁺. Moreover, the reusability of oxalic acid and [Bmim]Cl was demonstrated, and both could be reused up to six times without significant loss in activity.

Wang, Shizhuo published the artcileExperimental and theoretical study on the catalytic degradation of lignin by temperature-responsive deep eutectic solvents, COA of Formula: C8H15ClN2, the publication is Industrial Crops and Products (2022), 114430, database is CAplus.

Lignin is a renewable biomass resource with excellent application potential; however, the extremely complex structure of lignin renders it difficult to effectively degrade and use. In this context, it is necessary to identify a catalyst that can be easily recovered to increase the lignin degradation rate. In this paper, two temperature-responsive deep eutectic solvents (TRDESs), which can form homogeneous phases with reactants at a high temperature and sep. from the reaction system at low temperature, were designed to catalyze lignin degradation Based on the |HOMO-LUMO| gap, [Bmim]Cl and ChCl, which have a high catalytic activity, were selected from 22 deep eutectic solvents (DESs). [Bmim]Cl-EDTA (mole ratio = 1:1) was obtained by combining [Bmim]Cl and EDTA. ChCl-SA (mole ratio = 1:1) was obtained by combining ChCl and salicylic acid (SA). Results of COSMO-SAC modeling calculations and solubility experiments indicated that TRDESs can respond to temperature Specifically, these solvents can form a homogeneous phase with the reactants at high temperatures, thereby increasing the number and uniformity of the reaction sites. Moreover, the solvents can be separated from the reaction system at low temperature, which enables efficient recycling of the catalyst. Results of lignin degradation experiments indicated that the catalytic performance of [Bmim]Cl-EDTA is higher than that of the other DESs: the degradation rate of lignin is 83.63%, and the catalyst exhibits a satisfactory catalytic effect even after multiple cycles.

Qiao, Haiyu published the artcileEfficient preparation of all cellulose composite films using a plasticizing-rolling method, HPLC of Formula: 79917-90-1, the publication is Composites, Part A: Applied Science and Manufacturing (2022), 106968, database is CAplus.

Efficient manufacturing cellulose is a promising solution to solve severe environmental problems resulted from non-degradable plastics. Herein, we propose a plasticizing-rolling technique to manufacture cellulose featuring high cellulose ratios (50 weight%) and low temperature (65°C). Plasticization effect from plasticizers (BmimCl and LiCl) uniformly plasticizes cellulose while shear effect from rolling destroys the crystal area of cellulose, both increasing the mobility of cellulosic mol. chains. SEM images and XRD anal. reveal prepared films are all cellulose composite (ACC), cellulose I in the core area and cellulose II in the surface area. ACC films have high transparency (81%), tensile strength (73.6 ± 4.8 MPa), and thermal stability. The relationship of structure and properties of ACC films was also discussed and a particle-matrix composite model was proposed to analyze high transparency of ACC films. In conclusion, the proposed method presents a potential to efficiently produce high-performance cellulose materials at large scale.

Villemejeanne, Benoit published the artcileHalide based ionic liquid mixture for a sustainable electrochemical recovery of precious metals, Name: 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Journal of Environmental Chemical Engineering (2022), 10(1), 107063, database is CAplus.

Precious metal refining from ore or electronic devices includes hydrometallurgical processes with major concern about toxicity or wastewater production As an alternative, one-step electroleaching-electrochem. deposition process (EL-ECD) using ionic liquid mixtures was evaluated for palladium and gold recovery. A halide based ionic liquid combined with a diluting ionic liquid was chosen among ten electrolytes after cyclic voltammetry and potentiostatic experiments These low viscous electrolytes allow complexing Au and Pd, leading to metal leaching at low anodic potential. Moreover, the complexes formed could be simultaneously deposited at the cathode. Metal behavior is similar for all halide anions tested (chloride, bromide and iodide). Results show that chloride based mixtures are the more suitable electrolyte providing the highest leaching faradic yield. This process appears more sustainable than conventional processes (chlorination, cyanide leaching) thanks to the electrolyte stability limiting solvent losses but also workers exposition.

Im, Jaewan published the artcileStructural characteristics and thermal properties of regenerated cellulose, hemicellulose and lignin after being dissolved in ionic liquids, SDS of cas: 79917-90-1, the publication is Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) (2022), 365-375, database is CAplus.

This study investigated the use of ionic liquids such as 1-butyl-3-methylimidazolium chloride, 4-butyl-4-Me morpholinium chloride, 1-butyl-1-methylpiperidinium chloride, and 1,3-dimethylimidazolium methylphosphite to dissolve cellulose, hemicellulose, and lignin biomass, as alternatives to highly toxic organic solvents. The biomass treated with the ionic liquids is characterized by SEM, X-ray diffraction, thermogravimetric anal., and Fourier-transform IR spectroscopy. The X-ray diffraction results revealed that most of the biomass treated with ionic liquids had low crystallinity after treatment with the ionic liquids Thermogravimetric anal. confirmed that the pyrolysis temperature of the biomass treated with the ionic liquid decreased. However, it was found that the pyrolysis temperature of the biomass was increased again after the ionic liquid was washed with an antisolvent. This result was interpreted using Fourier-transform IR spectroscopy to show that the O-H hydrogen bonding of cellulose was restored. The exptl. results from this study can help provide a better understanding of the biomass regeneration mechanism of ionic liquids and increase the applicability of biomass in various fields.

Yahya, M. S. published the artcileDominance of hydrophobic attraction in attachment of microbubbles and Graphene oxide (GO), Synthetic Route of 79917-90-1, the publication is Chemical Engineering Science (2022), 117033, database is CAplus.

This paper presents the synthesis of GO-coated microbubbles which would be useful for environmental remediation and enhanced heat transfer applications. The mechanism of microbubble-GO attachment including electrostatic interactions, hydrophobic attraction, contact angle and Gibb’s free energy were determined Preliminary experiments indicated that water alone is not favorable, which thus necessitated the use of a bridging surfactant. The optimum attachment between microbubbles and GO occurred at the GO’s isoelec. point (IEP) in the ionic liquid as surfactant (IL), in which the IL concentration allowed GO to achieve maximum hydrophobicity. Therefore, it is inferred that hydrophobic attraction is the dominant force for microbubble-GO attachment with minor contributions from electrostatic interactions. Further studies showed that the longest carbon chain length IL, i.e. 1-Dodecyl-3-methylimidazolium chloride ([C₁₂mim]Cl) produced the most conducive environment for microbubble-GO attachment at its IEP concentration of 350 ppm.

Liu, Wei-Jie published the artcileHofmann-MOF derived nanoball assembled by FeNi alloy confined in carbon nanotubes as a magnetic catalyst for activating peroxydisulfate to degrade an ionic liquid, Computed Properties of 79917-90-1, the publication is Separation and Purification Technology (2022), 120945, database is CAplus.

As ionic liquids (ILs) are increasingly consumed, release of ILs into water environment has posed risks to aquatic ecol. due to their toxicities. Since 1-Butyl-3-methylimidazolium chloride (BMIMCl) represents the most typical IL, development of useful techniques to eliminate BMIM from water is urgent and critical While SO^•-₄-based oxidation processes are useful for degrading BMIM, very few studies have been conducted using peroxydisulfate (PDS), and almost no studies exist for developing heterogeneous activation of PDS to degrade BMIM. Thus, the aim of this study is to develop a useful heterogeneous catalyst for the first time to activate PDS for degrading BMIM in water. Herein, a special catalyst is developed from a unique Hofmann-type MOF ([Fe]pyrazine[Ni(CN)₄]) through carbonization to afford a nanoball assembled from carbon nanotubes (CNTs) with confinement of FeNi alloy nanoparticles. Such a FeNi@CNT (i.e., FeNiC) nanoball exhibits many advantageous features, including embedment of effective metals (Fe and Ni), strong magnetism, protection of FeNi by CNT, synergy of FeNi and CNT, and unique interwoven assembled structures, making FeNiC a promising heterogeneous catalyst for activating PDS to degrade BMIM. FeNiC is proven to exhibit a much higher catalytic activity (RSE = 0.0388) than Fe₃O₄ for PDS activation (RSE = 0.0155). FeNiC/PDS also shows a lower activation energy (i.e., 40.4 kJ/mol) for BMIM degradation then other reported values, revealing promising advantages of FeNiC. The activation mechanism as well as degradation pathway of BMIM degradation by FeNiC/PDS is also investigated here through theor. DFT calculations and exptl. evidences to provide valuable insights into degradation behaviors of BMIM using Hofmann MOF-derived catalysts.
