To enhance the dry cutting performance of YG8 cemented carbide tools, square-array pit-type micro-textures were fabricated on the tool rake face, and [BMIM]PF₆/5CB@PUF dual-core microcapsules were embedded into the micro-textures using a UV-curing filling method. This study used 300M steel as the workpiece material and employed an orthogonal experimental design to examine the effects of micro-texture parameters and microcapsule characteristics on the dry cutting performance of YG8 cemented carbide tools. The range analysis results indicate that the texture–edge distance is the dominant influencing factor, followed by microcapsule type, microcapsule content, and texture density. The best-performing cutting condition within the investigated experimental range was obtained with a texture–edge distance of 100 μm, a texture density of 20%, a microcapsule content of 20 wt.%, and a microcapsule type of [BMIM]PF₆/5CB@PUF. Compared with the untreated tool, the textured tool filled with microcapsules increased the cutting length by 12.9%, while reducing the cutting force, cutting temperature, and surface roughness by 38.35%, 29.65%, and 32.36%, respectively. EDS and XPS analyses reveal that the enhanced performance stems from the rupture of dual-core microcapsules during cutting. The subsequent continuous release of lubricants generates a stable film on the rake face, which minimizes direct tool-chip contact and friction. This improvement provides a novel strategy for achieving sustainable lubrication and enhanced efficiency in dry cutting operations.

The preparation of 5-hydroxymethylfurfural (5-HMF) from glucose is an important reaction in the field of solid acid-catalyzed biomass conversion. The reaction is usually carried out at high temperatures and pressures. In this paper, a nonmetallic solid acid catalyst CNs-PF 6 was synthesized from cheap melamine and hexafluorophosphoric acid (HPF 6 ) by low-temperature calcination and immersion method. The catalyst achieved the conversion of glucose to 5-HMF by photo-induction at a lower temperature (80 °C) and atmospheric pressure. And it also has a very high stability for recycling. The unique mechanism of photo-induced CNs-PF 6 catalyzing the conversion of glucose to 5-HMF has been elucidated by photoelectron characterization, transient absorption spectroscopy and theoretical calculations. Namely, under photoinduction, CNs-PF 6 possesses both Lewis acid and Brønsted acid properties. Since light simultaneously provides energy for the conversion reaction, it enables the reaction to proceed at lower temperatures and pressures. Combining light induction with acid catalysis fully leverages the synergistic effects between photocatalysts and solid acid catalysts. This research provides a new successful model for achieving biomass conversion at lower temperatures and pressures.

In this paper, a green solvent [BMIM] [PF 6 ] ionic liquid was selected for the extraction and separation of quinoline from simulated wash oil. The effects of extraction temperature, extraction time, and solvent oil ratio on the extraction of quinoline from wash oil were studied. The optimal process parameters were obtained by changing single factor conditions and optimizing the experiment using response surface methodology. When the temperature is 71 ℃, the time is 60 min, and the solvent oil ratio is 3:5, the extraction efficiency can reach 67%. The ionic liquids were recovered and their properties were investigated by infrared spectroscopy. The mechanism of quinoline extraction by ionic liquids was analyzed using infrared spectroscopy and GROMACS kinetic simulation calculations.

To obtain the basic data for the recovery of 1-methylimidazole from wastewater by extraction, the ternary liquid–liquid phase equilibrium data of the water (1) + 1-methylimidazole (2) + 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF6]) (3) system were determined using an equilibrium autoclave at the temperatures of 303.15 to 323.15 K and 101.32 kPa. The solute distribution coefficient (D) and the selectivity (S) of the ternary system were calculated in accordance with the experimental data. Their values were up to 1.39 and 41.17, respectively, which showed that the ionic liquid can extract 1-methylimidazole effectively. The experimental results showed that the temperature had a slight effect on the liquid–liquid equilibrium behavior. Meanwhile, the calculated results revealed that the selectivity coefficient decreased with the enhancing concentration of 1-methylimidazole in the ternary system and the increasing temperature. In addition, the nonrandom two liquid (NRTL) model was used for correlation of the ternary systems. The root-mean-square deviation value of 0.0218 indicated that the calculated results using the model were in good agreement with the experimental data and were reliable to apply to practice.

In this work, a quantitative structure–property relationship (QSPR) model based on atom-type electrotopological state (E-state) indices has been developed for predicting the dispersive liquid–liquid microextraction (DLLME) enrichment effect for aromatic organics by using 1-octyl-3-methylimidazolium hexafluorophosphate ([OMIM][PF 6 ]) ionic liquid as extractant. The enrichment factors of the aromatic organics obtained through DLLME-IL process were used as the dependent variable of the multiple linear regression (MLR) equation. The E-state indices of those organic compounds which combined together both electronic and topological characteristics of the analyzed molecules were used as molecular structure descriptors and the independent variable of the equation. The squared correlation coefficient R 2 for the MLR was 0.992 for the training set of 33 compounds. For the test set of 8 compounds, the linear regression coefficient was R 2 = 0.985. The results of this study showed that it can successfully predict enrichment factors of [OMIM][PF 6 ] in DLLME by using atom-type E-state indices, which can provide one more way for predicting the ability of ionic liquid to extract organic compounds based on their molecular structures.

In this study, we developed an electrochemical sensor utilizing a composite material consisting of zirconium‑copper bimetallic metal-organic framework functionalized with ionic liquid [BMIM][PF 6 ]. This composite material was fabricated by simple wet impregnation method, which not only maintains excellent electrocatalytic activity but also enhances electron transfer rate and electroactive surface area . The ZrCu-MOF-818/ILs composite modified electrode has been demonstrated as an effective tool for the detection of nitrite. The electrode exhibited a remarkable limit of detection (LOD) of 0.148 μM and wide linear ranges of 6–3000 μM and 3000–5030 μM. It is worth noting that the sensor displayed excellent reproducibility and repeatability, with relative standard deviation (RSD) values of 1.06% and 1.37%, respectively. Furthermore, the proposed method was successfully applied for the detection of nitrite in tap water and pickle juice.

A new sensitive method for antimony (III) determination by graphite furnace atomic absorption spectrometry (GFAAS) has been developed by using N-benzoyl-N-phenylhydroxylamine (BPHA) and 1-butyl-3-methylimidazolium hexafluorophosphate ([C4mim][PF6]) single drop microextraction. The single drop microextraction (SDMM) system is more competitive compared with other traditional extraction methods. Under the optimized conditions, the limit of detection (signal-to-noise ratio is 3) and the enrichment factor of antimony (III) are 0.01 μg·L−1 and 112, respectively. The relative standard deviation of the 0.5 μg·L−1 antimony (III) is 4.2% (n=6). The proposed method is rather sensitive to determinate trace antimony (III) in water.

The rapid development of dye industry has led to a significant amount of wastewater discharged. As a widely-used dye, toxic and non-degradable methylene blue is becoming a serious threat to our ecosystem. Thus, wastewater containing methylene blue must be treated properly. Considering the strengths of ionic liquid (IL) and metal organic framework (MOF) in molecular separation, a convenient solution strategy is proposed in this work for designing and preparing IL@MOF composite adsorbent in order to efficiently remove methylene blue from water. As a kind of water-stable MOFs, UiO-66 was synthesized by a one-pot method under very mild conditions using deep eutectic solvent (DES) as reaction media instead of conventional organic solvents. The easily obtained UiO-66-DES has superior MB adsorption kinetics but limited adsorption capacity. To mitigate this weakness, a computational and systematic IL screening framework is developed. [EtOHMIM][PF6] is eventually selected from 3569 candidates and incorporated into the UiO-66-DES. The resulted IL@MOF composite maintains the fast MB adsorption while importantly increasing the adsorption capacity from 45.85 mg/g to 227.57 mg/g. Given 10 mg/L MB solution, the removal rate is improved from 34% to 91% in 5 minutes. Meanwhile, the adsorption capacity is almost unchanged after 5 regeneration cycles, which offers great potentials for practical applications. Finally, the detailed mechanism analysis reveals that the loaded IL introduces new adsorption sites with stronger interactions with MB. These results show that the [EtOHMIM][PF6]@UiO-66-DES composite resulted from DES-assisted MOF synthesis and IL-based post-synthesis is a promising material for efficient MB wastewater treatment.

Catalytic CO 2 desorption from rich amine solution is a practical approach to reducing energy consumption for amine regeneration. In this study, for the first time, the catalytic effect of environmentally friendly, imidazole series ionic liquids ([Bmim]PF 6 , [Bmim]BF 4 , [Bmim]HSO 4 , [Bmim]NO 3 , [Bmim]CH 3 COOH, [Bmim]Cl, [Bmim]Br, and [Bmim]I) is evaluated in terms of CO 2 desorption rate, amount of CO 2 released, and heat duty. Overall, the [Bmim]PF 6 catalyst shows excellent catalytic activity for CO 2 desorption, increasing the quantity of CO 2 released by 21.35% and reducing the relative heat duty by 17.59%. In addition, the catalytic applicability of [Bmim]PF 6 for secondary and tertiary amine systems was evaluated. Of note, the homogeneous [Bmim]PF 6 catalyst presents good stability during 5 cycles. The catalyst/MEA (monoethanolamine) solution ratio of 3 wt% retained about 94% of the catalytic performance after five cycling tests without any reactivation step, showing the potential application of this desorption technology for CO 2 capture with lower heat duty.

Volatile organic compounds (VOCs) emitted from industrial activities and transportation pose significant health risks to humans and contribute to environmental issues. As a result, there has been growing interest in developing effective technologies for VOC removal. This study investigates the removal of low-concentration VOCs from air using a membrane catalytic process that combines a supported ionic liquid membrane (SILM) with a novel visible light-driven photocatalyst. The system, consisting of a 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM]PF6) SILM and N-doped La–TiO2 photocatalysts, achieves a mineralization rate of 40%–60% and a removal efficiency of approximately 75% for VOCs under visible light exposure for 10 hours. The synergistic effects of membrane separation and photocatalytic degradation significantly enhance the overall VOC removal efficiency compared to using either method alone. The membrane catalytic system demonstrates particular applicability and stability for various organic compounds, including toluene, acetone, chloroform, benzene, and xylene. Overall, this work presents a promising approach for the removal and mineralization of VOCs.

Sodium-ion batteries (SIBs) operating under high-voltages suffer from unstable cathode-electrolyte interphase (CEI) formed on the cathode surface , resulting in continuous electrolyte decomposition, surface reconstruction, transition metal dissolution, and eventually capacity decay. Therefore, designing high-voltage electrolyte and constructing the robust CEI are critical for high-energy SIBs. Herein, a localized high-concentration electrolyte (LHCE) is fabricated by dissolving sodium hexafluorophosphate in methyl ethyl carbonate, fluorinated ethylene carbonate and 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether, which demonstrates oxidative stability exceeding 6 V relative to Na + /Na. The dense and homogeneous inorganics-rich CEIs are generated by the preferential decomposition of PF 6 − anions during the electrochemical charge to 4.4 V, which lower interface impedance, facilitate Na + transportation and suppress subsequent side reactions. Consequently, the cell integrating high-voltage P2-Na 0.7 Li 0.03 Mg 0.03 Ni 0.27 Mn 0.6 Ti 0.07 O 2 cathode and Na anode exhibits a capacity retention of 87.3% after 200 cycles and a high-rate discharge capacity of 84 mA h g −1 at 20 C under a high cut-off voltage of 4.4 V. This work offers a feasible pathway to tailor electrolyte chemistry and interphase properties for practical next generation high-voltage SIBs.

It was the first report that the concentrated hydrolyzates from the enzymatic hydrolysis of dilute NaOH (3 wt%)-soaking rice straw at 30 °C was used to form [Bmim]PF 6 -hydrolyzate (50:50, v/v) media for bioconverting ethyl 4-chloro-3-oxobutanoate (COBE) into ethyl ( R )-4-chloro-3-hydroxybutanoate [( R )-CHBE] (>99% e.e. ) with recombinant E. coli CCZU-A13. Compared with pure glucose, the hydrolyzates could promote both initial reaction rate and the intracellular NADH content. Furthermore, emulsifier OP-10 (20 mM) was employed to improve the reductase activity. Moreover, Hp-β-cyclodextrin (0.01 mol Hp-β-cyclodextrin/mol COBE) was also added into this bioreaction system for enhancing the biosynthesis of ( R )-CHBE from COBE by E. coli CCZU-A13 whole-cells. The yield of ( R )-CHBE (>99% e.e. ) from 800 mM COBE was obtained at 100% in the [Bmim]PF 6 -hydrolyzate (50:50, v/v) media by supplementation of OP-10 (20 mM) and Hp-β-CD (8 mM). In conclusion, an effective strategy for the biosynthesis of ( R )-CHBE was successfully demonstrated.
