However, two challenges persist: rapid capacity degradation because of low conductivity and hindered ion intercalation pathways due to entanglements of polymer. This work presents a novel copolymer design of thiophene/butylthiophene (TH/BT) blocks integrated with multiwalled carbon nanotubes (MWCNTs). The rigid TH blocks enhance molecular crystallinity to expose electrochemically active thiophene rings, while the flexible BT segments promote the growth of copolymers around MWCNTs to establish an efficient 3D electron transport network. Through optimizing TH:BT ratio to 3:1, the balance between crystallinity and solubility is achieved and yields a block copolymer composite, designated as Cob(3:1)-TH+BT@CNT. Consequently, the anode shows superior performances: 1) enhances reversible capacity of 920 mAh g- 1 at 100 mA g- 1 (only 300 mAh g-1 for unmodified polythiophene@CNT); 2) maintains 105.0% and 100.6% capacity after 500 cycles at 1 and 2 A g- 1, respectively; and 3) preserves storage characteristics of thiophene rings near 0.2 V with an excellent rate performance. This novel rigid-flexible block structure increases the capacity of thiophene-based anode without the introduction of additional active groups, which provides new insights for the design of conjugated organic anode materials.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501609"},"PeriodicalIF":6.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145190495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, corncob is first used as a model feedstock due to its well-structured lignocellulosic composition. Through systematic optimization of parameters such as alkali concentration, temperature, reaction time, alkali type, and cosolvent, tetramethylammonium hydroxide (TMAH) is identified as the best choice for isolating hemicellulose with high purity. By further implementing optimized conditions (80 °C for 1 h), a urea-assisted TMAH system (comprising 6 wt% TMAH and 10 wt% urea) achieves a 74.94% extraction yield of high-purity hemicellulose (85.7%) from corncob. The versatility of this system is then confirmed by its ability to dissolve hemicellulose from various biomass sources, including Chinese fir, poplar, and bamboo. Additionally, integrating membrane separation within the TMAH-urea system enables scalable fractionation, significantly cutting down acid consumption and antisolvent use by at least 80%. A 500-fold scale-up maintains a close yield of 70.14%. The solvent system exhibits excellent recyclability, sustaining a yield of 64.74% after three recycling cycles.

The gas diffusivity strongly affects the initial performance for coelectrolysis SOECs. The durabilities of SOECs during coelectrolysis are generally lower compared to those of SOECs during steam-only electrolysis and solid oxide fuel cells during power generation. The present work investigates the effect of gas diffusivity in the fuel electrode on the initial durability during coelectrolysis at H2O/CO2 = 2 and 700 °C for fuel electrode-supported microtubular SOECs with varying geometries and using different fuel electrode materials. Upon varying the geometries and materials, high initial performances are observed for cells with low polarization resistances associated with the gas-related processes in the fuel electrode. However, the initial deterioration during coelectrolysis remains unchanged for cells using the same fuel electrode materials with different geometries. Material variations lead to changes in the fuel electrode microstructure, such as the pore size and the pore distribution, which in turn affect the gas diffusivity in the fuel electrode substrate. Additionally, it is found that microstructural variations in the fuel electrode significantly influence the initial durability of coelectrolysis SOECs.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501182"},"PeriodicalIF":6.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145190569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep eutectic solvents (DESs) have the advantages of being versatile and tunable, among which three-constituent DES (glycerol/ChCl/AlCl3·6H2O) is found efficient for lignin extraction in biomass fractionation. Herein, how this kind of three-constituent DES affects the fractionation efficiency of lignin is investigated in detail at molecular level. Molecular dynamics simulations indicate that glycerol and ChCl provide strong interaction with the small fragments of lignin. Chloride anion is found to contribute mostly electrostatic interaction to lignin-solvent interactions, while choline cation and glycerol provide strong van der Waals interaction, which also contributes to the higher solubility of the small fragments of lignin. According to DFT calculations, Al3+ is more likely to coordinate with glycerol, forming chelated [Al(C3H8O3)2]3+, which can effectively catalyze the cleavage of βO4 bond of lignin through Lewis acid catalysis, including the isomerization of hydroxyl via E1 and Markovnikov reactions, significantly reducing the energy barrier by about 24 kcal mol-1, favoring the fractionation of lignin. This mechanism is also verified experimentally. This work gives out deep understanding for lignin fractionation in solvent pretreatment, providing guiding clues for the design of more efficient solvent system in biomass utilization.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501796"},"PeriodicalIF":6.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The isothermal thermogravimetric analysis indicated that SA exhibited extremely lower volatility than acrylic acid (AA), which suggests that SA could be used as a green and safe alternative to AA overcoming issues related to AA volatility and toxicity that can be experienced during AA manipulation. Several SESO-based thermosetting resins are obtained after the curing process performed by thermal treatment in the presence of a radical initiator. SESO shows complete curing after 6 h, faster than acrylated ESO (AESO), along with a good copolymerization ability with several reactive comonomers, such as styrene, myrcene, and pentaerythritol tetraacrylate, producing resins with similar mechanical (Young's modulus ranging from 6 to 1160 MPa) and thermal (glass transition temperature ranging from 17 to 61 °C) properties and superior biobased content to those AESO-based.

However, achieving high nitrile selectivity while suppressing over-reaction to amides remains a significant challenge. In the present work, a Zr-doped OMS-2 catalyst that demonstrated remarkable efficiency for the selective ammoxidation of benzyl alcohol to benzonitrile is developed. Under optimized conditions, an impressive yield of 84.9% and selectivity of 89.9% are achieved, using aqueous ammonia as the nitrogen source and molecular oxygen as the oxidant. Solvent effect studies reveal that the adsorption of benzyl alcohol and benzonitrile significantly influences the activity and selectivity of the reaction. Kinetic investigations reveal that the reaction proceeded through a three-step consecutive first-order mechanism, with the high nitrile selectivity being kinetically controlled. Comprehensive characterization demonstrates that the incorporation of Zr4+ enhances the Lewis acidity of OMS-2, increases the population of active oxygen species, and effectively lowers the activation energy barrier. Controlled experiments elucidate the reaction mechanism in detail. The catalyst exhibits excellent stability and broad substrate generality, selectively converting a wide range of aromatic alcohols to their corresponding nitriles with high yields.

Besides traditional pyrometallurgical and hydrometallurgical processes used for metal recovery, deep eutectic solvents (DESs) have recently emerged as greener alternatives for leaching metals from spent cathodes of LIBs. A key drawback is, however, the unresolved recovery of the DES, whose cost can represent 30-60% of the leachate, thereby reducing the overall sustainability of the process. Herein, we used the leachates as electrolytes for supercapacitors. DESs based on phytic acid provided leachates with mass loadings of 40 mg of lithium cobalt oxide (LCO) or lithium nickel manganese cobalt oxide (NMC) per gram of DES. The typically poor performance of acidic leachates as electrolytes was addressed through chemical and solvent treatments. Neutralization with tetramethylguanidine expanded the electrochemical window, while dilution with water and/or water-dimethyl sulfoxide mixtures enhanced ionic mobility and rate capability. As a result, the processed leachates delivered energy densities of ≈17.9 Wh kg-1 at 488.35 W kg-1 and 5.77 Wh kg-1 at 4343.72 W kg-1, in the range of those provided by much less cost-efficient electrolytes such as 21 m LiTFSI.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501306"},"PeriodicalIF":6.6,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145172249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
