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}

Herein, electrolytes that combine harmless polyethylene glycol with slightly salty water are developed, which enables the capture of CO2 in a supercapacitor cell of up to 79 mmol of CO2 per kilogram of electrode material while operating at a current density of 30 mA g-1, a voltage of 2.5 V, at 40 °C, and under neutral pH conditions. Interestingly, applying negative charge protocols up to -2.5 V increases the amount of CO2 adsorbed per kilogram of electrode to 356 mmol. This is attributed to both the ejection of preadsorbed bicarbonate species from the pores and their slow migration kinetics near the electrode exposed to CO2 gas toward the positively charged counter electrode. This finding indicates that the CO2 capture and release mechanism exhibits no dependence on the direction of the charge. These polymer electrolytes lead to a threefold increase in the gravimetric energy stored compared to similar devices operating at ≈1 V that utilize microporous carbon electrode materials. The system also reveals excellent stability and corrosion resistance under long-term cycling at high voltages. This advanced technology marks a major advancement in sustainable carbon capture solutions.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501259"},"PeriodicalIF":6.6,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123886","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}

This study focuses on the development and optimization of hydroxide-based absorbents for CO2 capture and subsequent hydrogenation to formate. The research built upon previous work with hydroxide-based systems, which successfully captured atmospheric CO2 but left open questions regarding the effects of solvents and cations on capture efficiency. A systematic experimental and theoretical investigation is conducted to evaluate a series of organic cations (tetrabutyl ammonium and phosphonium) and different solvents (DMSO, H2O, MeOH) in the CO2 capture and further hydrogenation to formate. The findings demonstrate a CO2 capture efficiency of up to 1.0 mol CO2 per mol of TBA+ (tetrabutylammonium) in DMSO/water, with water boosting the overall sorption process. Molecular dynamics simulations revealed that solvent composition controls solvation and aggregation behavior. Additionally, the hydrogenation of the captured bicarbonate is optimized using Ru-based complexes. Ru3(CO)12 achieved a formate yield of up to >99% under mild hydrogen pressure (5 bar), smaller pressure reported so far for DACC. Density of functional theory calculations provided key insights into the reaction pathway. These insights contribute to the advancement of efficient DACC technologies by reducing H2 pressure requirements while maximizing CO2-to-formate conversion.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501284"},"PeriodicalIF":6.6,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123959","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}
