In this study, Se-Sb alloy coatings were successfully fabricated for the first time via constant potential electrodeposition from a choline chloride–ethylene glycol deep eutectic solvent. The correlation between deposition potential and the morphology, composition, crystal phase, optical, and electrical properties of the coatings was systematically investigated. The results showed that as the deposition potential shifted in the negative direction, the fibrous morphology of the coatings initially became denser and subsequently looser. Correspondingly, the Se content first decreased and then increased, while the Sb content exhibited the opposite trend. The crystalline structure was primarily characterized by an amorphous Sb 2 Se 3 phase. Although both the bandgap and photocurrent response initially increased and then decreased with more negative deposition potentials, the coatings consistently exhibited excellent p-type semiconductor characteristics. Chronoamperometry (CA) analysis indicated that the nucleation mechanism of Se-Sb alloys transitioned from diffusion-controlled three-dimensional (3D) progressive nucleation to diffusion-controlled 3D instantaneous nucleation as the deposition potential shifted from −0.45 V to −0.65 V. Furthermore, cyclic voltammetry (CV) analysis revealed an induced co-deposition mechanism: Se was first deposited on the FTO substrate, which subsequently induced the co-deposition of Se and Sb to form the Se-Sb alloy coatings. Finally, a comparison with coatings annealed at 300 °C demonstrated that annealing significantly improved the crystallinity, resulting in the formation of crystalline Sb 2 Se 3 . However, the photocurrent response decreased by a factor of 5.18. These findings suggest that the as-deposited Se-Sb alloy coatings exhibit superior photoelectrical performance compared to their annealed counterparts, highlighting their promising potential for photoelectric applications.

This study presents a green strategy for synthesizing amorphous cobalt sulfide (Co–S) bifunctional electrocatalysts via a choline chloride–ethylene glycol deep eutectic solvent (DES) under ambient conditions, addressing ionic coordination dynamics and defect engineering for enhanced solid–state ionic/electronic transport in energy conversion. By modulating the equilibrium between Co 2+ and S₂O₃ 2- ions in Ethaline, we fabricated monodisperse Co–150S nanoparticles (~ 78 nm) with tailored sulfur content (S/Co = 1.9), an amorphous architecture, and abundant oxygen vacancies. These structural features synergistically optimized ionic diffusion pathways and electronic conductivity, achieving exceptional hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) activities in alkaline media. The Co–150S/NF electrode demonstrated a volcano-like sulfur-dependent activity profile, achieving the highest electrochemically active surface area (ECSA, 3.7 cm 2 ) and ultralow overpotentials of − 105 mV (HER) and 277 mV (OER) at 10 mA cm⁻ 2 , comparable to benchmark Pt/C and RuO₂ catalysts. Post-electrolysis characterization revealed dynamic structural reorganization during HER and OER operations, involving over 80 at% sulfur depletion and the formation of metastable Co-rich phases that maintained catalytic functionality. In overall water splitting, the system required only 1.62 V to drive 10 mA cm⁻ 2 with minimal activity decay (1.5 mV h⁻ 1 over 26 h). Mechanistic investigations revealed that sulfur incorporation initiates a multiscale optimization process: (i) DES–mediated ionic confinement prevents particle aggregation, promoting uniform nanosphere formation; (ii) modulation of the electronic structure through nonstoichiometric Co–S coordination; and (iii) defect engineering through the enrichment of oxygen vacancies. This study provides insights into ionic coordination mechanisms in non–aqueous solvents and defect–mediated ion transport in amorphous solids, suggesting a potential strategy for developing electrocatalysts applicable to related energy storage technologies.

Pulp molded generated from renewable bagasse as biodegradable packaging materials has been widely viewed as an eco-friendly and cheap way to substitute the current huge consumption of nondegradable plastics, and deep eutectic solvents (DES) pretreatment are a promising approach to obtain high-yield pulp efficiently and sustainably. However, mainstream binary-component DES still suffers issues of high viscosity and corrosiveness. This study put forward a ternary-component DES (3C-DES) with the addition of ethylene glycol (EG) into choline chloride (ChCl) and P-toluenesulfonic acid (PTSA) and examined pretreatment performance and optimal DES ratio for thread rolling bagasse via compositional analysis and physicochemical characterization. Moreover, density functional theory calculations were used to reveal structures and weak interactions of different ratios of 3C-DES, and a novel 3C-DES pretreatment chemical-mechanical pulp and pulp molded were finally prepared. The results indicate that the 3C-DES with ChCl:PTSA:EG molar ratio of 1:1:3 is most effective, evidenced by more than 97.94% lignin removals. The 3C-DES pretreated mechanical pulp exhibits superior fiber properties, whereas the hot-pressed pulp molded shows excellent physical properties and thermal stability. Thus, the proposed 3C-DES has great potential to obtain high-yield high-performance pulp molded with low cost and environmental sustainability.

A ternary deep eutectic solvent (DES) consisting of choline chloride, lactic acid, and urea in a molar ratio of 1:2:2 was used to pretreat chamomile residue, followed by carbon dots (CDs) preparation using a one-pot solvothermal method . The CDs prepared under the suitable conditions had a high quantum yield of 47.34% and could be used as a bifunctional fluorescent probe for the detection of tartrazine and Fe(III). The concentration of tartrazine or Fe(III) had a good linear relationship with the fluorescence intensity of CDs that the determination coefficient ( R 2 ) was 0.9957 and 0.9943, and the limit of detection (LOD) was 40 nM and 119 nM, respectively. After verifying the different fluorescence quenching mechanisms of CDs by these two substances, a quantitative analysis was performed on real samples with recoveries of 90.70%∼104.29%. Overall, this study provided a promising technology for chemical conversion from low-cost chamomile residue to attractive bifunctional fluorescent probe.

Lignin extraction and upgrade are the great importance to lignin valorization but are closely related to raw material sources, separation methods, and conditions. The advantage of this work is to firstly exploit an efficient and practical approach to extract highly reactive lignin from waste mulberry branches (MB) using green deep eutectic solvent (DES). To better understand the relationship between the extraction conditions and the properties of lignin, the influences of DES components, extraction temperature and time on the extraction efficiency, average molecular weight, chemical structure, and thermal stability of lignin were systematically investigated and analyzed. The synergistic effects of processing conditions resulted in high extraction efficiency with 62.9% of yield and 94.5% of purity. Under optimal conditions with LA/ChCl ratio of 2:1, extraction temperature of 150 °C, and time of 6 h, the obtained lignin had relatively low molecular weight ( M n = 1900 g/mol and M w = 2841 g/mol) and narrow distribution (PDI = 1.49), simultaneously had high total hydroxyl content of 9.15 mmol/g. Benefiting from high hydroxyl content and low molecular weight, the extracted lignin possessed excellent miscibility and reactivity which could participate in polymerization reaction to synthesize lignin-derived rigid polyurethane foam (LRPUF). The integration of the highly reactive lignin significantly improved the specific compressive strength and modulus of LRPUF to 6.4 and 76.0 MPa/(g/cm 3 ), which increased by 7% and 22.4% than those of petroleum-based RPUF. Therefore, this work not only provided an efficient and practical strategy for lignin extraction and upgrade, but also proposed a potential of high value-added utilization of waste mulberry branches.

After anthocyanins were extracted from plant cells, deep eutectic solvent (DES) spontaneously promoted the stability of anthocyanins. To better understand the stability of anthocyanins in DES, and in particular the role of co-extracted cell wall polysaccharides, blueberry anthocyanins were initially recovered with four different DESs (choline chloride (CC):citric acid (CA), CC:lactic acid (LA), CC:glycerol (G) and CC:ethylene glycol (EG)). Then, the impacts of DES formulation and co-extracted polysaccharides on the stability of blueberry anthocyanins were systematically evaluated. Results showed that the extraction efficiency for anthocyanins was closely related to the polarity of DES, with CC:CA exhibiting the highest total anthocyanins content. Twelve anthocyanins were identified, and DESs showed selectivity for different anthocyanins. DESs co-extracted different proportions of low-methoxyl pectin rich in homogalacturonan (HG) or rhamnogalacturonan I (RG I) backbone structure together with hemicellulose. The stability of anthocyanins in DESs was discriminated by the degradation kinetic parameter (half-life of degradation- t 1/2 ). The DES formulation did not fully explain the variation in t 1/2 values. Instead, the t 1/2 values were found to correlate positively with HG and hemicellulose contents, resulting from the interactions between anthocyanins and polysaccharides. Except for CC:G that showed the highest t 1/2 at temperatures ≥ 80 °C, CC:CA afforded higher t 1/2 under varied temperatures (≤60 °C), pH and light exposure. Finally, the anthocyanin-containing DESs exhibited biocompatibility and antioxidant capacities. These results offer new insights for the understanding of the enhanced stability of anthocyanins in DES, and promote the direct application of anthocyanin-containing DESs in food-related fields.

Through a simple room-temperature process, different amounts of Keggin-type quaternary ammonium silicotungstate were successfully encapsulated into the metal–organic framework (MOF) material ZIF-67. The catalysts were characterized using Fourier transform infrared (FT-IR) spectroscopy, X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and BET analysis. An extraction and catalytic oxidation desulfurization system was studied using H2O2 as an oxidant and a deep eutectic solvent (DES) as an extractant. Using the 43.06%-SiW12@ZIF-67 composite under optimal reaction conditions, DBT present in a model oil could be deeply and effectively removed. The catalyst was reused 6 times, and the desulfurization rate still exceeded 90%. Finally, a possible desulfurization mechanism is proposed.

Efficient fractionation of reed biomass and tailored downstream high value-added applications are crucial for biorefining sustainability. To address the issues of hemicelluloses non-recovery and lignin structure destruction during DES pretreatment, a green and efficient alkaline deep eutectic solvent (ADES) pretreatment strategy was developed. The strategy aims to achieve efficient fractionation of reed biomass, while providing uncondensed lignin, hemicelluloses with high structural retention, and easily digestible cellulose residues for bioenergy and chemicals. Results demonstrated that the proposed ADES pretreatment strategy exhibited excellent capability in deconstructing biomass component, achieving a delignification efficiency of 82.95 wt%-96.13 wt% (ADES-NAP/CAP/CEM systems at 120–160 °C for 10 min). Meanwhile, lignin fractions had excellent antioxidant activity and well-preserved structure (high content of β- O -4 aryl ether bonds), which facilitated to the development of downstream applications and monomer production (29.34 wt%-41.16 wt% via reductive catalytic degradation at 180–260 °C). On the other hand, the pretreatment efficiently removed hemicelluloses (83.49 wt%-97.61 wt%), while enabling the recovery of high-purity hemicelluloses with structural integrity well-preserved. The ADES cellulose residues achieved 60.39 wt%-97.68 wt% fermentable glucose yield at low enzyme loading (10 FPU/g) during enzymatic saccharification, with a total biorefinery yield exceeding 81 %. In summary, the proposed ADES pretreatment strategy not only solved the problem of hemicelluloses degradation during DES pretreatment but also realized efficient separation, conversion and utilization of all components within reed biomass.

Artemisia selengensis is a medicinal and edible plant, whose tender stems are widely consumed as a folk vegetable in China. However, due to their bitterness, Artemisia selengensis leaves (ASL) are often discarded as a waste material, resulting in resource wastage. This study aimed to characterize ASL's chemical composition, develop a “green” extraction method, and explore its potential bioactivity. Using LC-MS, 72 compounds were identified. To extract 7 representative caffeoylquinic acids (CQAs), the mixture of choline chloride and ethylene glycol (1:6) was selected as the optimal deep eutectic solvent (DES), and the extraction parameters were optimized as follows: extraction time of 21 min, temperature of 44°C and ultrasonic power of 420 W. Based on molecular docking analysis, both 3,5-diCQA and 1,5-diCQA exhibited strong binding affinity to xanthine oxidase (XO), consistent with their potent XO inhibitory effects (IC 50 = 3.69 and 3.35 nmol/mL, respectively). In addition, a greater XO inhibition was observed for the DES extract (IC 50 = 6.05 μg/mL) compared with the methanol extract (IC 50 = 22.5 μg/mL). This study not only helps to reduce ASL disposal's environmental load and boost its agricultural value, but also sets a green model for similar vegetable waste to aid circular agriculture.

ChCl-MEA DES was used to absorb CO 2 from gasification syngas consisting of CO 2 , CO, CH 4 , and H 2 . This study investigated the effect of water addition on CO 2 absorption capabilities of ChCl-MEA DES with different mole ratios of ChCl to MEA, and different absorption temperatures. It was found that water addition had a positive effect on CO 2 solubility of ChCl-MEA DES, with the maximum obtained value of 0.5 mol-CO 2 /mol-DES for aqueous ChCl-MEA DES with 75%vol water at absorption temperature of 40 °C and pressure of 9 bar. In general, water addition increases CO 2 solubility and absorption rate of ChCl-MEA DES. ChCl-MEA DES 1:5 mol ratio was able to benefit from water addition up to 75%vol water content. While ChCl-MEA 1:10 had its CO 2 solubility increase with water addition up to 50%vol, after which, it declined. Investigation into water addition at different absorption temperatures revealed that water addition at 40 °C produced the most significant CO 2 solubility enhancement compared to water addition at 20 °C and 60 °C. This might be caused by the tradeoff between the effects of high temperature in decreasing ChCl-MEA DES viscosity and lowering its CO 2 solubility. Highest CO 2 /CO selectivity for ChCl-MEA DES 1:5 was found to be around 34.6, CO 2 /CH 4 was 26.7, and CO 2 /H 2 was 4. Water addition was found to have slight reducing effect on the CO 2 selectivity of ChCl-MEA DES.

Efficient bamboo pretreatment achieved 97.02% hemicellulose and 85.13% lignin removal under mild conditions. • High furfural yield of 86.86% was attained via in situ conversion of hemicellulose-derived sugars. • Low activation energy (20.93 kJ/mol) facilitated rapid xylose dehydration to furfural. • 1 H NMR showed water regulated DES viscosity and hydrogen bond strength. An acidic DES consisting of glycerol, choline chloride and p-toluenesulfonic acid (TA) was employed for bamboo pretreatment, enabling efficient removal of hemicellulose (97.02%) and lignin (85.13%) while retaining 82.66% of cellulose under mild conditions (100 °C, 2 h, 40 mmol TA). After lignin separation, the hemicellulose-derived sugars in the DES solution were subsequently converted in situ to furfural with a desirable yield of 86.86% (140 °C, 2 h), and kinetic analysis revealed a low activation energy of 20.93 kJ/mol for the furfural formation. A small amount of water (3%) was introduced into the spent DES, which disrupts the original rigid hydrogen bond network of the DES through the interaction with glycerol hydroxyl groups. The weakening of hydrogen bond strength may promote the release of acidic proton of TA, further facilitating the acid-catalyzed dehydration of xylose to furfural. On the other hand, the viscosity of DES was largely reduced with the introduction of water, which probably improved the mass transfer of furfural to MIBK, enabling the desirable furfural yield from the in-situ conversion of hemicellulose-derived sugars in DES system. This study presents a facile strategy for the in-situ conversion of hemicellulose to furfural, avoiding the cumbersome separation of hemicellulose-derived carbohydrates from DES system.

Hexagonal boron nitride (h-BN) with a large specific surface area and unique optoelectronic properties has good application prospects in many fields. The liquid phase exfoliation method is considered the most promising method for achieving controllable preparation of boron nitride nanosheets (BNNSs), but the low-cost, relatively environmentally friendly and efficient liquid phase exfoliation is still difficult to achieve. Choosing a suitable solvent system is the key to achieving efficient exfoliation. Deep eutectic solvents (DESs) have the advantages of simple synthesis, low cost, high thermal and chemical stability and strong biocompatibility and are expected to be green solvents for preparation of BNNSs . In this paper, it was found that the properties of DESs and its interaction with h-BN had a significant impact on the electrochemical exfoliation of h-BN. The intercalation effect of DES and the compatibility between DES and h-BN were the main factors affecting the yield, while the quality of BNNSs mainly depended on the decomposition and expansion effect of DES. This rule also can be applied to prepare highly conductive and hydrophilic two-dimensional material Ti-MXene. This research explores the structure–activity relationship between two-dimensional materials and DESs, and provides a theoretical basis for the environmentally friendly and efficient preparation of two-dimensional materials using DESs as exfoliation solvents.
