Here, a thermally activated carbon cloth (CC450) that simultaneously addresses iodine confinement and reaction kinetics through precisely engineered hierarchical porosity is reported. By optimizing oxidative calcination at 450 °C in air, CC450 develops a unique pore structure with nanopores for strong I3 - adsorption and interconnected macropores for rapid ion transport, while maintaining the intrinsic conductivity and flexibility of CC. The CC450 cathode achieves an exceptional balance of performance metrics: high areal capacity, ultralow self-discharge (3.05% in 24 h), and outstanding cycling stability (94.63% capacity retention over 1000 cycles), which represents the best-reported performance for binder-free carbon electrodes in Zn-I2 batteries. Mechanistic studies reveal that CC450's 12-fold reduction in charge-transfer resistance and low activation energy for I- oxidation stem from its optimal surface chemistry and pore hierarchy. The self-discharge tests and UV-vis spectroscopy confirm efficient iodine shuttle suppression. Unlike complex nanomaterial-based hosts, CC450 is fabricated through a scalable ambient-air process, offering immediate industrial relevance. This work provides critical insights into pore-engineered carbon hosts for metal-iodine batteries and establishes a generalizable strategy for achieving high-energy, long-life energy storage systems.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501455"},"PeriodicalIF":6.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123871","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}

Recently, covalent organic frameworks (COFs) have become the most competitive platforms in various photocatalysts owing to their customizable structure and function, as well as high orderliness. However, the inefficient utilization of photoinduced charge carriers severely impedes the improvement of the catalytic efficiency of COFs. In this work, two regioisomeric imine-linked COFs, ETTA-N1MBTz COF and ETTA-N2MBTz COF, incorporating N-methyl-benzotriazole moieties with different methyl positions, are constructed using Schiff-base polycondensation. The photoelectric properties, electronic states, and exciton binding energies of both COFs can be easily manipulated through the N-methyl positional isomerization strategy. Importantly, N-2-methyl substituted ETTA-N2MBTz COF shows a superior photocatalytic efficiency with hydrogen evolution rate up to 17,900 μmol g-1 h-1 under visible-light irradiation, far outperforming its isomeric ETTA-N1MBTz COF (1360 μmol g-1 h-1) under the same conditions. This finding offers an effective strategy for regulating electronic state and charge transfer dynamics in COFs toward efficient solar-energy conversion and storage.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501657"},"PeriodicalIF":6.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123938","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}

These COFs are formed by reversible imine bonds, and their adaptation to acidic environments takes long periods of time, which is difficult for chemical synthesis. As a result, it is great to be able to synthesize a new class of amide-linked (CONH) nano-COFs with fewer active sites. Although amide-based COFs have been reported for gold recovery, the COFs are prepared using postmodification techniques (e.g., dynamic nucleophilic exchange and oxidation). In this study, electrically neutral nano-COF (Nano-COFA) and ionic nano-COF (Ionic-nano-COFA) linked by amide bonds are synthesized. The recovery of gold by Nano-COFA (Ionic-nano-COFA) is primarily a fast chemisorption process. Nano-COFA (Ionic-nano-COFA) has a maximum adsorption capacity of 1334 (1736) (25 °C), 2044 (2541) (35 °C), and 2933 (3200) (45 °C) mg g-1, respectively. Selective adsorption and cyclic regeneration experiments demonstrate that the two types of nano-COFs exhibit high selectivity for gold and reusability. Additionally, the CN bonds act as reducing agents, changing Au3+ to Au0 without affecting the crystallinity of the COFs. For the treatment of real electronic wastewater, both types of nano-COFs show high selectivity and adsorption efficiency.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501155"},"PeriodicalIF":6.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123949","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}

These devices offer high-power density, rapid charge/discharge, and long cycle life, making them suitable for applications requiring quick energy bursts. Moreover, they bear lesser dependency on critical raw materials, enhancing their sustainability. Despite their technological maturity, little is known about their environmental and economic implications from a life cycle perspective. This review offers an insight into life cycle assessment and life cycle costing studies evaluating the environmental impacts and economic viability of SCs. The analysis synthesizes existing research, identifies trends, and highlights key knowledge gaps. By providing a systematic overview of the life cycle sustainability metrics for SC technologies, this study contributes to a deeper understanding of their role as a viable and sustainable energy storage solution. Due to heterogeneous system boundaries and product systems found in literature, a clear estimation of average environmental impacts and cost performance remains challenging. Additionally, the sustainability implications of next-generation SCs are not fully understood. Further research is needed to establish comprehensive sustainability assessments, improve methodological consistency, and guide future development.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500583"},"PeriodicalIF":6.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129720","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 response, bio-based \"green\" solvents have emerged as environmentally benign substitutes, offering reduced toxicity and lower carbon footprints. However, their industrial implementation is challenged by high viscosity, energy-intensive recovery, and limited life-cycle sustainability when employed in single-use processes. Herein, organic solvent nanofiltration (OSN) as an energy-efficient and selective membrane-based technology for recycling green solvents is explored. OSN membranes enable solvent purification by selectively removing impurities while preserving solvent integrity, reducing waste generation and energy consumption. OSN performance in the recovery of widely used green solvents, including acetone, acetonitrile, ethyl acetate, Cyrene, dimethyl isosorbide (DMI), and γ-valerolactone (GVL), is evaluated. The potential of OSN for in-process solvent recycling is demonstrated, with a case study on the recycling of Cyrene in synthetic leather production, demonstrating the feasibility of OSN membranes in maintaining solvent purity and enabling a more sustainable manufacturing process.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501117"},"PeriodicalIF":6.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123922","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}
