However, their application is limited by poor conductivity, severe polysulfide shuttling, and slow redox kinetics. While conventional RT Na–S batteries suffer from the dissolution and migration of soluble polysulfide intermediates, sulfur confinement within microporous carbon can restrict long-chain polysulfide dissolution and promote a more spatially confined sulfur conversion pathway, thereby improving cycling stability and efficiency. This study involved the synthesis of hierarchically porous carbon materials from Luffa cylindrica through temperature controlled carbonization, which are then utilized as sulfur host matrices. The modified S/LC-1000 composite exhibits a well-developed micro/mesoporous structure and strong sulfur–carbon interactions. The optimized microporous/mesoporous LC-1000 host likely suppresses the dissolution of long-chain sodium polysulfides and promotes a more confined sulfur redox pathway. This pathway modulation, driven by sulfur confinement within micropores, enables efficient polysulfide immobilization while simultaneously facilitating enhanced ion/electron transport and improving overall electrochemical reversibility, thereby leading to improved stability and performance. The S/LC-1000 exhibits an initial discharge capacity of 1730 mAh g–1 and sustains about 1360 mAh g–1 after 300 cycles at 0.5 C while sustaining about 677 mAh g–1 after 10,000 cycles at 5C, demonstrating enhanced rate capability and diminished charge-transfer resistance. This study presents a sustainable and efficient approach for developing biomass-derived carbon hosts to address critical constraints of RT Na–S batteries and enhance their application.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"279 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the widespread use of fossil-based, non-recyclable polyester-cotton blends in textiles presents substantial challenges to advancing sustainability and establishing a circular economy. Bio-based polyesters are considered as potential alternatives for producing textiles with lower environmental impacts, but they frequently exhibit critical limitations as fiber materials in textile applications. Here, we present a practical approach for evaluating the spinnability of emerging bio-based polymers and report the development of poly(butylene furanoate) (PBF) as a renewable and chemically recyclable alternative to conventional polyesters. PBF exhibits high molecular weight via scalable melt polycondensation and excellent melt-spinnability into fine, high-tenacity fibers. The resulting fibers are readily dyeable under mild conditions and, they can be chemically recycled from polycotton blends via mild methanolysis depolymerization, yielding the original monomers in high yield and purity while preserving the integrity of the cotton fibers. The corresponding recovered monomers can be conveniently repolymerized into high-quality PBF, demonstrating a fully circular material platform. These findings revealed that PBF could be a promising biobased material for next-generation sustainable textiles, combining desirable performance, processability, renewability, and product circularity.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"44 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To realize the harmless disposal of heavy metal Cr(VI) and efficient hydrogen energy recycling, it is highly imperative to explore high-performance multifunctional catalytic materials. Herein, sulfur-vacancy (Sv) modified ZnIn2S4 (ZIS) is synthesized via a one-step hydrothermal method, aiming to regulate the generated free radicals via piezo-photocatalytic conditions. Sv defects are distributed around indium atoms, which endows ZnIn2S4 with excellent piezo-photocatalytic activity. The Sv-ZIS achieves 100% Cr(VI) removal efficiency within 100 min, which is 1.12-fold and 5.03-fold higher than those under sole light irradiation and single ultrasonication, respectively. It also possesses a H2O2 yield of 158 μmol g–1 h–1 through two-electron ORR (∼80%) and WOR (∼20%) pathways. Moreover, the H2 production rate is 29.5 μmol g–1 h–1. In-depth investigations into defect engineering demonstrate that Sv defects induce the construction of an internal polarized electric field, which greatly accelerates the migration of charge carriers. The proposed catalytic mechanism elucidates that H2O2 production competes with Cr(VI) reduction for electrons, and piezocatalysis can efficiently boost the photocatalytic activity for Cr(VI) reduction, H2O2 and H2 production. This work offers a promising strategy to alleviate environmental contamination and address energy scarcity.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"37 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Certain electrolyte additives can only provide one-dimensional regulation, which is insufficient to synergistically suppress multiple failure mechanisms. This study reports a “multifunctional single-molecule” additive strategy utilizing acetaminophen (AP) to achieve ultralong-term stability of the zinc anodes. The synergistic interaction between the phenolic hydroxyl (−OH) and amide (−NHCOCH3) functional groups in AP creates a stable Zn2+ solvation environment, effectively suppressing the hydrogen evolution reaction. Concurrently, the electron-rich aromatic rings form a hydrophobic dynamic passivation interface protective layer, facilitating the reversible deposition and stripping of Zn. Consequently, the introduction of AP significantly enhances electrochemical performance, such as the Zn//Zn symmetric cell exhibits a lifespan extended to 1000 h at 1 mA cm−2 and 1 mAh cm−2, while the AZICs maintains a high specific capacity of 49.8 mAh g−1 and a Coulombic efficiency close to 100% after 60,000 cycles at a high current density of 7 A g−1.

However, its current commercial price of up to US$ 700 kg–1 severely limits its engineering applications. Ball milling, characterized by low energy consumption and high efficiency, offers considerable potential for substantially reducing the production cost of MgH2. Nevertheless, this method suffers from an intrinsic self-limiting effect: the MgH2 product shell mechanically shields the underlying Mg from external energy input and impedes hydrogen diffusion into the unreacted Mg core, resulting in products with low purity. Herein, a mechanical pre-defect engineering strategy is proposed. Based on Hertzian contact theory, high-modulus SiC nanoparticles are employed to amplify localized stress and induce vacancies and dislocations within the Mg matrix. Together, ab initio molecular dynamics (AIMD) simulations, density functional theory (DFT) calculations, finite-element simulations, and multiscale characterizations reveal that the SiC-induced defect network promotes H migration through strain- and vacancy-mediated pathways, thereby overcoming the mechanical shielding imposed by the MgH2 shell. Consequently, MgH2 with a hydrogen storage capacity of 7.4 wt % is synthesized in one step at a mild ball-milling speed of 200 rpm without heat treatment. Moreover, its hydrogen desorption peak temperature is reduced to 347 °C, which is 111 °C lower than that of commercial MgH2.

Herein, we demonstrate that the molecular polarity of the D–A dyad serves as a descriptor for rationalizing charge transfer behavior upon photoexcitation in the structurally related D–A CMPs. Two CMPs, denoted as TP-CMP and TN-CMP, were synthesized using the same electron donor—triptycene (TATP), but different electron acceptors, 1,4,5,8-naphthalenetetracarboxylic dianhydride (NDA), and pyromellitic dianhydride (PMDA), respectively—and evaluated for CO2 photoreduction. TP-CMP delivers a substantially higher CO production rate of 25.78 μmol h–1g–1 with 98.07% selectivity, outperforming TN-CMP (12.16 μmol h–1g–1 with 97.22%). Despite the stronger electron-withdrawing ability of NDA in TN-CMP, TP-CMP exhibits higher D–A polarity, more favorable charge separation, and a lower free-energy requirement for *COOH formation, collectively consistent with its superior CO2-to-CO activity.
