Crystalline silicon (Si) is widely used in modern electronics. Si is commonly produced through a series of energy-intensive reactions (>700 °C). It is thus urgent and significant to explore more economically and environmentally-benign synthetic strategies for crystalline Si at low temperature. In this contribution, we report an efficient method to prepare crystalline Si from silicon tetrachloride at the low temperature of 100 °C with an ionic liquid (IL) as electrolyte. Physicochemical characterization revealed that as-deposited crystalline Si with a diamond cubic crystal structure exhibited a dominant (111)-orientation. Moreover, in-depth insights into the growth mechanism of crystalline Si was shed light upon herein. Furthermore, the smart electrodepositing platform of crystalline Si from ILs would open up a new avenue for low-temperature metallurgy of Si.

A novel poly[1-vinyl-3-benzyltriethylammonium proline ionic liquid] membrane(PIL/PVDF membrane) were prepared through the blending poly[1-vinyl-3-benzyltriethylammonium proline ionic liquid](P[Pro][TEA])-poly(vinylidene fluoride)(PVDF) phase inversion method. A series of PIL/PVDF membrane characterization (NMR, FT-IR, SEM, EDS, and XPS) was performed. The properties of PIL/PVDF membrane (contact angle, water flux, mechanical properties, thermal stability,electric charge property, specific surface area and pore diameter) were evaluated. A solid phase extraction − high performance liquid chromatography (SPE-HPLC) method for separation/analysis of quercetin was developed. The factors affecting the adsorption and elution (time, dosage, pH etc.) were investigated. Under optimal conditions, the method has been successfully applied to the separation/analysis of quercetin in tea, and the recovery rates are satisfactory (86.4–106.0 %). The concentration factor of quercetin was 10. The adsorption capacity of PIL/PVDF membrane towards quercetin was 22.1 mg g −1 . The extraction mechanism was preliminarily discussed. The established SPE-HPLC method was simple and reliable, which provided application prospects for extraction and detection of quercetin.

The potential of reverse electrodialysis for harvesting osmotic energy is severely limited by ion concentration polarization (ICP), a phenomenon that restricts power output and confines the technology to the laboratory scale (< 0.4 µW). This challenge is overcome with an ionic liquid confined porous MXene (IPM) system that integrates strategies across two scales. At the microscopic level, sub-nanometer channels are engineered using porous MXene and confined ionic liquids to reduce mass transfer resistance and optimize ion transport. Concurrently, at the macroscopic level, a micropore array design spatially decouples the diffusion interfaces to effectively suppress the ICP effect. This dual-scale approach increases power density by 53.6% and achieves a maximum output power of 3.47 µW, which is nearly ten times higher than that of similar work. The work demonstrates a robust pathway for overcoming critical power limitations, advancing osmotic energy conversion toward industrial renewable energy applications.

A fast, environmentally friendly, and reproducible method is proposed to synthesize SnO nanoparticles in an ionic liquid which consists of choline chloride, urea, and SnCl 2 ·2H 2 O. The nano-sized SnO particles with a size of about 20–30 nm can be synthesized in 1 min without any further treatment and complicated infrastructures. When prolonging the reaction time, the SnO nanoparticles can be self-assembled into micro-sized balls with the hydrangea geometry. High-resolution transmission electron microscopy shows that the SnO nanoparticle consists of tetragonal structured crystals with the grain size of about 4–6 nm. X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy further certify the composition, chemical state, and chemical band of the prepared SnO samples. Moreover, the direct band gap of the SnO samples is highly dependent on the particle architectures. A larger band gap value of about 3.80 eV is obtained in the nano-sized SnO which may be due to the quantum size effect.

This paper provides the strategy to prepare luminescent sandwich structured hybrid materials [Ln(L)4]−IM+–Al/Ti (Ln = Eu, Sm; L = 2-thenoyltrifluoroacetonate (TTA); Ln = Tb, L = trifluoroacetylacetonate (TAA)) based on sol–gel derived hosts of Ti–O or Al–O networks. The ionic liquid compound 3-(2-carboxyethyl)-1-methylimidazolium bromide (IM+Br−) plays double roles of both connecting the lanthanide compounds with an ion exchange reaction and linking matrices through its carboxylic group. Subsequently, a series of hybrid soft materials of alumina and titania xerogels centered with lanthanide complexes are prepared via the hydrolysis and polycondensation of aluminum isopropoxide or tetrabutyl titanate. These hybrid soft xerogels are characterized under FTIR, XRD, UV-VIS diffuse reflection absorption spectra, SEM, TGA and especially luminescence spectroscopy. The results prove that it is an effective way to prepare [Ln(L)4]−IM+–Al/Ti hybrid soft materials with favorable photoluminescent behaviors. It is noticeable that [Sm(TTA)4]−IM+–Ti can render white light under broadband excitation for a certain content of Sm3+.

Developing high-safety electrolytes is very important to improve the safety and operative temperature of lithium batteries. In this study, a heat-resistant and non-flammable electrolyte is constructed by introducing a functionalized ionic liquid N-methyl-N-methoxyethyl-pyrrolidinium bis(fluorosulfonyl)imide (Pyr 12O1 FSI, IL1) into porous polyurethane (PU) matrix. IL1 contains ether functional group, which can increase the chain flexibility of IL and provide more ion migration channels. Moreover, IL1 shows high compatibility with PU matrix because the intermolecular hydrogen bond is formed by N H groups of PU and ether oxygen of IL1, which is evidenced by Fourier transform infrared spectroscopy (FTIR) tests and density functional theory (DFT) calculations. The binding energy further corroborates the enhanced intermolecular interaction between IL1 and PU. Owing to the superior characteristics of IL1 and synergetic coupling with PU, PU-IL1 electrolyte exhibits good electrochemical performance and endows LiFePO 4 /Li (LFP/Li) battery with a high specific capacity of 135 mA h g −1 and 99% capacity retention after 100 cycles at 0.2C, 30 °C. In addition, the LFP/Li battery with PU-IL1 electrolyte exhibits a high capacity of 134 mA h g −1 (0.5C) and it remains 98% after 100 cycles at a high temperature of 80 °C.

Quasi-solid-state electrolytes (QSSEs) based on ionic liquids are recognized as one of the frontrunners of electrolytes for ensuring the safety and high energy density of next-generation lithium batteries. However, the incapacity of such systems to meet the performance demands of batteries is significantly subject to the properties of the electrolyte and the intricacies of related interfacial processes. Recently, we have designed a high-performing pyrrolidinium bis(trifluoromethylsulfonyl)imide (Py 14 TFSI) based QSSE (Py-Gel), with introducing LiBF 4 and LiCl, which served as a system for probing the dynamic Li deposition mechanism. Herein, we focus on understanding the mechanisms of Py-Gel formation and examining the chemistry and structure as well as the properties of the solid-electrolyte interphases (SEIs) formed in the Py-Gel and their influences on Li deposition. Spectroscopic characterizations suggest the existence of a cross-linked structure in Py-Gel, for which multiple intermolecular/intramolecular hydrogen bondings and ionic coulumbic interactions among Py cations, TFSI − anions, and Li salts are responsible. The Py-Gel electrolyte exhibits exceptional electrical properties at room temperature. Different SEIs are prepared in the Py-Gel via electrochemical protocols to elucidate that the synergy between a well-featured electrolyte and an outstanding SEI is vital for stable cycling of Li metal anodes in such a QSSE. Graphical An ionic liquid-based gel electrolyte is developed, showcasing exceptional electrical properties at room temperature. Different SEIs are prepared in this electrolyte via electrochemical protocols to elucidate that the synergy between a well-featured electrolyte and an outstanding solid-electrolyte interphase is vital for stable cycling of Li metal anodes in such system.

As one of the main components of ionic liquid-based composite electrolytes, nanoparticles play a major role in determining the performance of such electrolytes. In this study, four different TiO2-based nanoparticles are introduced into ionic liquid electrolytes to systematically investigate the influence of their conductivities and surface chemistries on the performance of composite electrolytes. Compared with conventional insulating nanoparticles, high-conductivity nanoparticles are free of blocking junctions, and the surface region of the nanoparticles can act as an additional pathway for ionic conduction. Meanwhile, the surface chemistry of the nanoparticle strongly determines the viscosity, network stability, and microscopic morphology of an ionic liquid-based composite electrolyte, thus affecting the ionic conductivity. Therefore, the highest conductivity of 4.29 mS cm–1 is achieved by the ionic liquid-based composite electrolyte with the SC-HC-TiO2 nanoparticle at a weight of 10 wt %, which has high conductivity and rich amino functional groups. DSCs using SC-HC-TiO2 show a high efficiency of 8.12% due to the simultaneous improvement of photocurrent density (Jsc), open-circuit voltage (Voc), and fill factor (FF).

Continuous glucose monitoring (CGM) in interstitial fluid (ISF) is often compromised by temperature and pH variations, hydration–dehydration cycles, and interfering species, which lead to unstable enzyme immobilization and inefficient electron transfer. To overcome these challenges, we developed a hybrid material comprising ionic-liquid–functionalized poly(glycidyl methacrylate) microbeads (ILMbs) with internal immobilization of GOx, interpenetrated with carboxylated carbon nanotubes (CNT). This covalently interconnected ILMbs/CNT framework establishes a dual ion–electron conductive network that maintains enzyme hydration, buffers local pH, and facilitates efficient electron transport. Glucose oxidase (GOx) immobilized within this matrix exhibits high catalytic activity and exceptional stability against microenvironmental perturbations. The resulting ILMbs/CNT/GOx sensor achieved sensitive and reliable glucose detection across physiological pH (6.5–7.5) and temperature (25–40 °C) ranges, maintaining a stable current response during extended operation and under exposure to common interferents. The sensor retained over 94% of its initial current response after 21 days of storage, exhibited less than 5% signal fluctuation over 30 continuous CV cycles and displayed a clear, stepwise amperometric response to glucose concentrations from 0 to 11 mM, demonstrating excellent long-term stability, repeatability, and sensitivity. This materials-based strategy successfully integrates microenvironmental protection with enhanced conductivity, offering a robust platform for fabricating durable, enzyme-based biosensors capable of reliable performance in complex ISF-like environments.

To address the growing demand for efficient low-concentration CO2 capture from flue gas, functionalized ionic liquid (IL) hybrids─integrating ILs’ intrinsic CO2-philicity (specific functional group-CO2 interactions) and porous supports’ structural merits (high specific surface area, tunable pores, robust framework)─have emerged as promising adsorbents. In this work, a kind of novel polyamine IL (PIL) hybrid with narrowly distributed mesopores and ultrahigh IL loading over 70 wt % was fabricated by immobilizing the PIL triethyltetramine trifluoromethanesulfonate ([TETA][TfO]) onto a hydrophobic resin (XAD) featuring wide mesopores and a small fraction of macropores. At 313 K, 70 wt % [TETA][TfO]@XAD exhibited a high CO2 adsorption capacity of 3.09 mmolCO2/g-adsorbent at 1 bar and 2.35 mmol CO2/g-adsorbent at 0.15 bar. Notably, under simulated humid flue gas conditions (15 vol % CO2/5 vol % H2O balanced with N2), the PIL hybrid still could maintain a relatively stable adsorption capacity of 1.31 mmol CO2/g-adsorbent, which is comparable to that under dry flue gas conditions (1.24 mmol CO2/g-adsorbent, 15 vol % CO2 balanced with N2). Furthermore, after three consecutive adsorption–desorption cycles, the PIL hybrid maintained structural integrity and stable CO2 adsorption performance without significant attenuation under both dry and humid environments. The superior CO2 separation performance was attributed to the chemical interactions between CO2 and multiple amino groups (one secondary amine as well as two primary amines) of [TETA]+, coupled with the synergistic effect of the in situ-formed mesoporous structures. This work provides a feasible strategy for the rational design and development of mesoporous PIL hybrids for the efficient capture of low-concentration CO2 from flue gas.

Light-responsive proton conductors represent an attractive research direction owing to their potential in intelligent devices and responsive sensing applications. Herein, we present a cooperative functionalization strategy to construct an MOF-based light-regulated proton-conducting material, MOF-808-AZOA-IL, by integrating azobenzene-4,4′-dicarboxylic acid (AZOA) and an ionic liquid (IL) into the MOF-808 framework. AZOA serves as a photoactive unit to endow light responsiveness, while the IL molecules form a continuous proton-conducting network, enhancing the concentration and mobility of protons. This synergy results in a proton-conduction on/off ratio up to ∼2000 of MOF-808-AZOA-IL, with excellent stability over repeated UV light on/off cycles. This work demonstrates that the incorporation of AZOA and IL synergistically enhances the light-regulated proton conduction of MOF-808, offering a reliable strategy for designing advanced stimuli-responsive proton-conductive systems.
