Conventional methods for synthesizing nano-sized metal-organic frameworks (nano-MOFs) often rely on additives or extra conditions, overlooking the critical role of solvents. Here, we highlight tetramethylene sulfone (TMS, or sulfolane) as a versatile solvent for nano-MOF synthesis. TMS forms strong solvation structures with metal ions and inhibits ligand deprotonation, enabling control over particle size. Using TMS, we synthesized ZIF-65 [Zn(2-nIm)2, 2-nIm = 2-nitroimidazole], ZIF-8 [Zn(2-mIm)2, 2-mIm = 2-methylimidazole], UiO-66 [Zr6O4(OH)4(BDC)6, BDC = 1,4-dicarboxybenzene acid], and MOF-199 [Cu3(BTC)2, BTC = 1,3,5-benzenetricarboxylic acid] with significantly smaller particle sizes compared to traditional solvents like ethanol (EtOH). Systematic analysis on the growth of ZIF-65 revealed distinct growth behaviors: in TMS, slower kinetics allowed the coexistence of nucleation and growth over an extended period, leading to an increase in particle number while maintaining relatively constant size; in contrast, EtOH promoted rapid growth followed by Ostwald ripening, resulting in larger particles and reduced particle number over time. By adjusting reactant concentration, metal-to-ligand ratio, and reaction temperature, we achieved facile size modulation of ZIF-65 nanoparticles. This work underscores the importance of solvents in nano-MOF synthesis and offers a robust strategy for tailoring MOF particle size, advancing applications in catalysis, biomedicine, and beyond.

Electrolyte solutions of lithium tetrafluoroborate dissolved in sulfolane are applied in dual-ion batteries. A graphite positive electrode in this kind of solutions delivers a reversible anion storage capacity over 80 mAh g−1 at potentials over 4.5 V vs. Li/Li+. The structures of anion-graphite intercalation compounds are investigated in detail by the combination of in situ X-ray diffraction (XRD) and in situ Raman spectroscopic measurements.

Pretreatment has been regarded as the most efficient strategy for conversion of lignocellulosic biomass to fermentable sugars. In this work, sulfolane pretreatment was performed to break the intricate structure of shrub willow for inhabitation of the enzymatic accessibility to holocellulose. The effects of varying pretreatment parameters on enzymatic hydrolysis of shrub willow were investigated. It was found that sulfolane was more compatible with lignin instead of carbohydrate, and the loss of carbohydrate could be attributed to water and acid generated from sulfolane. The optimum conditions leading to maximal sugar recovery from enzymatic saccharification were confirmed. After pretreatment of shrub willow powder in sulfolane at 170 °C for 1.5 h with mass ratio of sulfolane to substrate of 5, the sugar release could reach 555 mg/g raw materials (352 mg glucose, 203 mg xylose) when combining 20 FPU cellulase, 20 CBU β-glucosidase, and 1.5 FXU xylanase, representing 78.2 % of glucose and 56.6 % of xylose in shrub willow. This enhanced enzymatic saccharification was due to delignification and removal of a proportion of hemicelluloses, as confirmed by X-ray diffraction analysis, scanning electron microscopy, Fourier-transform infrared spectroscopy, thermogravimetric analysis, gas chromatography, and ionic chromatography. Thus, these studies prove sulfolane pretreatment to be an effective and promising approach for biomass to biofuel processing.

A high-voltage electrolyte can match high-voltage positive electrode material to fully exert its capacity. In this research, a sulfolane plasticized polymer electrolyte was prepared by in situ photocuring. First, the effect of the sulfolane content on the ionic conductivity of the gel polymer electrolyte was investigated. Results showed that the ionic conductivity variation trend was in good agreement with the exponential function model for curve fitting. Second, the activation energy was calculated from the results of the variable temperature conductivity tests. The activation energy was inversely proportional to the sulfolane content. For the sulfolane content of 80 wt. % in gel polymer electrolyte (GPE)-80 (19.5 kJ/mol), the activation energy was close to conventional liquid electrolyte (9.5 kJ/mol), and the conductivity and electrochemical window were 0.64 mS/cm and 5.86 V, respectively. The battery cycle performance test showed that the initial specific discharge capacities of GPE-80 and liquid electrolyte were 176.8 and 148.3 mAh/g, respectively. After 80 cycles, the discharge capacities of GPE-80 and liquid electrolyte were 115.8 and 41.1 mAh/g, and the capacity retention rates were 65.5% and 27.7%, respectively; indicating that GPE-80 has a better specific discharge capacity and cycling performance than the liquid electrolyte. SEM images indicated that GPE-80 can suppress the growth of lithium dendrites. The EDS test showed that GPE-80 can inhibit the dissolution of metal ions in the cathode material.Keywords:lithium battery;sulfolane;gel polymer electrolyte;high-voltage electrolyte;UV curable

The poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) is expected to prepare electrolytes with wide electrochemical window owing to its excellent antioxidant capability. However, the inert lithium ion conduction of the C–C skeleton severely limits its electrochemical application. In this work, high-voltage-resistant sulfolane (SL) is used as a plasticizer into the PVDF-HFP skeleton to prepare gel electrolytes. Moreover, to alleviate the incompatibility of SL with lithium metal by the strong dipole–dipole interaction between poly(ethylene oxide) (PEO) and SL, a plasticized PVDF-HFP/PEO gel polymer electrolyte (PPS-GPE) was achieved, which exhibits a high ionic conductivity of 1.67 × 10–4 S cm–1 and an electrochemical stability window of 4.8 V. The assembled Li||LiCoO2 cells show a high average discharge capacity of 153 mA h g–1 between 3.0 and 4.4 V, with a retention of 77% within 400 cycles at 0.2 C. This work provides a new strategy for the development of high-voltage, high energy density, and high safety lithium metal batteries.

The anion storage behavior of graphite positive electrode in a dual-ion battery is closely related to the solvation of anion in the corresponding electrolyte solution. The classical electrolyte solutions of LiBF 4 -sulfolane (SL) have long been recognized in the community of lithium batteries and still appear promising in dual-ion batteries. Nevertheless, the solvation of BF 4 − by SL has seldom been addressed before. In this study, the solvation states of SL-BF 4 − are adjusted by varying LiBF 4 concentration or introducing auxiliary salts of LiPF 6 or SBPBF 4 (SBP: spiro-(1,1′)-bipyrrolidinium) in the electrolyte solutions of Li/graphite dual-ion cells. The electrochemical storage processes of SL-BF 4 − anions in graphite electrodes are investigated through in situ X-ray diffraction measurements. Two kinds of graphite intercalation compounds (GICs) with contrastive intercalation gallery heights (IGHs) have been discovered, which are ascribed to the storage of different kinds of SL-BF 4 − anions in graphite electrode. The interactions between ions and SL in the electrolyte solutions are characterized by Fourier transform infrared spectroscopy and then correlated with the performance of Li/graphite cells.

The high voltage stability (> 5.5 V) makes sulfolane (SL) an excellent electrolyte solvent candidate for high specific energy lithium-ion batteries. However, the stable solid electrolyte interphase (SEI) cannot be generated on the surface of graphite particles with SL , limiting its application. To solve the interface incompatibility, we introduce fluoroethylene carbonate (FEC) and lithium nitrate (LiNO 3 ) in SL-based electrolyte for constructing an inorganic-rich SEI on graphite. The comprehensive characterizations and simulations demonstrate that combined effect of additives facilitates the formation of additive-derived LiF-Li 3 N enhanced inorganic-rich SEI. The proposed electrolyte shows stable cycling performances with 324.89 mAh/g and 97.93 % after 50 cycles in Li/graphite half-cells, compared with the capacity of 24.54 mAh/g and the capacity retention of 19.4 % in SL-without additives. Importantly, the electrolyte system obtains a capacity retention of 71 % and the capacity of (127.93 mAh/g) is higher than that without additives (110.21 mAh/g) at 4.4 V after 200 cycles. This work solves the incompatibility of SL-graphite with low-cost additives, and is beneficial to realize the commercial application of sulfolane in high specific energy batteries.

A novel phase splitter, namely, sulfolane, was proposed to advance the traditional monoethanolamine (MEA) absorption technology for CO2 capture by simultaneously promoting the absorption rate and lowering heat duty. The phase-splitting phenomenon was observed after the CO2 loading level had exceeded 0.73 mol CO2/L, thereby generating a CO2-rich MEA upper layer and a lower layer containing sulfolane. Sulfolane facilitated CO2 absorption because of its strong affinity with acid gases, which resulted in an absorption rate 2.7 times higher than that of the conventional MEA process. The process simulation using Aspen Plus indicated that the regeneration heat with the MEA/sulfolane mixture as a solvent substantially decreased to 2.67 GJ/t-CO2, which was 31% lower than that of the conventional MEA process (3.85 GJ/t-CO2). Moreover, the sensible heat and vaporization heat of MEA/sulfolane were markedly decreased by 62.4% and 47.9%, which could be ascribed to the decreased stripping volume and relatively high CO2 partial pressure caused by liquid–liquid phase separation. The proposed system is proved to be a promising candidate for the advancement of CO2 capture techniques with high CO2 absorption capacity, rapid absorption rate, and low-energy penalty.

The experimental solubility of β -octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) in binary solvent mixtures of sulfolane + (H 2 O, acetonitrile, and ethanol) was measured at temperature ranging from (298.15 K to 343.15 K) by dynamic method under atmospheric pressure. The results showed that the solubility of β -HMX monotonously increases with increasing mole fraction of sulfolane at a given temperature in the studied binary solvent mixtures. Furthermore, the experimental solubility data in binary solvents were fitted using the modified Apelblat equation, the GCM model and the Jouyban-Acree model successfully. Hirshfeld surface analysis and molecular electrostatic potential (ESP) were employed to visualize close contacts and charge distribution of β -HMX and solvents. In addition, the molar dissolution thermodynamic properties of the solution of different binary solvent mixtures, such as Gibbs free energy, enthalpy and entropy, were calculated and analyzed based on the van’t Hoff equation and the experimental solubility data. Solid-liquid surface tension and surface entropy factor of β -HMX were estimated by the experimental solubility data. The solubility of β -HMX in sulfolane based binary solvent systems will provide essential support for the further study of crystallization and spheroidization of β -HMX in industry.

Sulfolane plasticizes PEG-based electrolyte for aqueous Mg-ion batteries. • Sulfolane modulates solvent microenvironment and relieves PEG chain entanglement. • Balanced electrolyte presents wide ESW, low viscosity and high ionic conductivity. • V 2 O 5 //PTCDI full cell delivers improved capacity and superior cycling stability. Aqueous magnesium-ion batteries offer a safe, low-cost, and sustainable energy storage solution, yet their development is impeded by the narrow electrochemical stability window (ESW) of conventional aqueous electrolytes. Although polyethylene glycol (PEG)-based electrolytes provide an expanded ESW, their high viscosity and low ionic conductivity severely limit ionic transport. Herein, sulfolane is introduced as a plasticizer to regulate the physicochemical properties of PEG400-based electrolytes. Across the tested PEG/SUL compositions, sulfolane incorporation substantially reduces electrolyte viscosity and enhances ionic conductivity, with the conductivity increasing from 480 μS cm −1 to 3390 μS cm −1 , while the selected PEG/SUL-11@20%H 2 O electrolyte retains a broad ESW of approximately 3.570 V . Raman and 1 H NMR analyses suggest that the sulfonyl groups in sulfolane interact with PEG400 chains, thereby modifying the local PEG chain environment and mitigating chain entanglement. Considering the trade-off among ESW, viscosity, ionic conductivity, and electrode compatibility, PEG/SUL-11@20%H 2 O was selected as a balanced formulation. The V 2 O 5 //PTCDI full cell assembled with the selected electrolyte delivers a discharge specific capacity of 147.7 mAh g −1 at 100 mA g −1 and retains 85% of its capacity after 600 cycles, demonstrating promising capacity and stable cycling performance. This sulfolane plasticization strategy effectively addresses the conductivity limitation of PEG-based aqueous electrolytes and provides a promising route toward advanced electrolytes for aqueous magnesium-ion batteries.

Direct conversion of cellulose into levulinic acid and furfural in sulfolane media with the aid of water and H 2 SO 4 was performed at 140–220 °C under the pressures of 0–1.5 MPa. This approach could obtain 72.5 mol% levulinic acid and 11.5 mol% furfural formation under an optimal condition in which the mass ratio of sulfolane, water and H 2 SO 4 was 90:10:1. It was found that the decrease of water content led to an increasing yield of furfural and that the maximum furfural yield (51.1 mol%) could be obtained in the absence of water. The synergism of sulfolane and water in the selective liquefied system was demonstrated to be responsible for not only reinforced effect of optimizing and isolating the target products but also for reducing re-polymerization and side reactions. Furthermore, sulfolane in our case could be recycled and re-used for the conversion of cellulose with the same yield, which shed light on the remarkable potential for future industrial application.

Graphical The height of intercalation : Lithium difluoro(oxalato)borate is introduced to LiBF 4 -sulfolane (SL) solutions for dual-ion batteries, and the graphite electrodes’ storage behavior of anions is studied. Each anion can intercalate into graphite with SL, and different intercalation gallery heights are formed. Intermediate height is not observed, and species inside graphite are determined. Some previous studies have found the synergistic effect of mixed anions in dual-ion batteries (DIBs). In this work, both lithium tetrafluoroborate (LiBF 4 ) and lithium difluoro(oxalato)borate (LiDFOB) were dissolved in sulfolane (SL) solvent, and the resultant solutions were applied for DIBs. The storage behavior of mixed anions in natural graphite positive electrodes was investigated. In-situ X-ray diffraction measurements revealed both anions could participate in the formation of graphite intercalation compounds. Their evolution followed with the decreasing tendency of discharge capacities as the content of LiDFOB increased in solutions. The exchange of anions was discussed.
