Nevertheless, the development of Li-S battery is plagued by the fatal shuttle effect of soluble lithium polysulfides (LiPSs) and sluggish reaction kinetics. Herein, the lithium tailing containing zinnwaldite activated after mechanochemical process is introduced to modify separators of Li-S battery for the first time. The activated zinnwaldite-containing lithium tailings (ALZT) consist of quartz, K-feldspar, kaolinite, and zinnwaldite. It not only possesses rich polar active sites such as Si, Al, Fe, and O ions to immobilize LiPSs but also contains higher Fe3 + content than zinnwaldite-containing lithium tailings (LZT), which significantly accelerates the redox kinetics of LiPSs. A novel composite PP separator modified by ALZT combined with conductive carbon black (ALZT@Super P@PP) has been prepared for Li-S battery. ALZT@Super P@PP separator not only shows superior electrolyte affinity, faster electrolyte wetting speeds, higher lithium-ion transference number, and ionic conductivity but also effectively enhances the LiPS trapping ability and significantly accelerates the transformation kinetics of LiPSs. Remarkably, Li-S batteries with ALZT@Super P@PP exhibit superior rate performance. The green protocol reported here paves the way for utilizing tailings in Li-S battery applications, enabling green uprecycling of mining waste.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501746"},"PeriodicalIF":6.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224764","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}

However, its potential for producing high-value carbon-based materials and its application in energy-related areas remain largely underutilized. In this work, a green and scalable strategy is reported for constructing a free-standing carbon nanofiber (CNF) film by electrospinning using lignin as the carbon precursor, with uniformly embedded MoS2 nanoparticles to endow integrated catalytic function. The resulting MoS2/CNFs film exhibits excellent structural integrity, enabling its direct use as a binder-free and current-collector-free cathode framework for lithium-sulfur (Li-S) batteries. Furthermore, the embedded catalytic components can chemically adsorb lithium polysulfides and enhance sulfur redox reaction kinetics. As a result, Li-S cells with MoS2/CNFs-based cathode demonstrate excellent cycling stability, maintaining a capacity of 609.3 mAh g-1 after 200 cycles at 1C. This work highlights a promising approach for transforming low-cost lignin into multifunctional electrode materials, offering both structural robustness and catalytic activity for next-generation Li-S batteries.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501698"},"PeriodicalIF":6.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211192","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, we report a novel photothermal ammonia synthesis strategy employing synergistic 3d transition metal-lithium hydride (TMs-LiH) composites. The TMs-LiH system (comprising V-, Cr-, Mn-, Fe-, Co-, and Ni-LiH composites) exhibits universal catalytic performance at low temperatures (100-200 °C), forming a characteristic \"plateau curve\" that indicates ammonia synthesis activity is less dependent on the specific TM component. Crucially, catalytic activity collapses entirely under identical thermal conditions in the absence of light, underscoring the pivotal role of photothermal effects in activating the reactants. Notably, compared to conventional thermochemical ammonia synthesis, the TMs-LiH catalysts under light illumination demonstrate a significant reduction in activation energies and reaction orders for H2 and NH3, revealing enhanced hydrogenation efficiency and ammonia desorption kinetics. Among the tested composites, Fe-LiH exhibits the highest catalytic activity, prompting further investigations into its unique reactivity. Fe-LiH induces a strong interplay with N2 with the assistance of light, driving the reductive elimination of hydridic hydrogen to H2, which likely creates a reduced Fe-LiH1-x interface that favor nitrogen fixation to form lithium amide species (LiNH2). Subsequent hydrogenation of LiNH2 on Fe-LiH1-x proceeds facilely to produce NH3.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501716"},"PeriodicalIF":6.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211173","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 approach is useful for reactions with similar mass-to-mass proportion (substrate to product). For processes with mass-to-mass change, or for fermentations, where the relationship substrate to product is elusive, GWP equations using product titers are more straightforward. This article introduces such product-titers-based GWP equations estimating the CO2 released from energy (up- and downstream), as well as from the waste treatment, namely wastewater and solvents. Equations are applied to discuss whether aqueous (bio)transformations with product titers of 1 g L-1 and extractive downstream are sustainable. When effluents are not recycled, >6000 kg CO2 kg product-1 is generated, because large aqueous media (1000 L) and solvents (1000-3000 L) are needed for one product kilogram. Even when solvent and water effluents are almost completely recycled (95%), >100 kg CO2 kg product-1 is still generated. For better environmental figures, process intensification with less diluted systems is mandatory. Setting product titers of ≈20 g L-1 with large recycling loops (95%) and mild wastewater treatment decrease the overall GWP to ≈10 kg CO2 kg product-1. GWP estimations at early development are useful in improving processes with low TRLs.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501831"},"PeriodicalIF":6.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145204991","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}

They are based on Bi as affordable and nontoxic electrocatalyst, to facilitate decentralized and cost-efficient reduction of CO2 to formic acid. To develop flexible GDE materials, their catalyst composition is optimized by studying systematically inexpensive Bi/Bi2O3 mixtures. During initial evaluation at technically relevant current density (150 mA cm-2, 21 h), the best composition achieve high Faradaic efficiency (FE) (≈90%) and the loss of catalyst is minor. In three demonstrative examples of realistic current patterns based on intermittent electricity, the performance and resilience of the optimized GDE is consistently very good in terms of high FE (≈90%) and stable synthesis rates of formate. However, loss of catalyst is partially increased, especially when GDEs are depolarized between electrolysis phases. Nonetheless, the GDE materials already show robust performances despite swift adjustments of current density (60 s) without any optimization of operational parameters so far. Based on these results, flexible operation of these GDE can be optimized to minimize cathodic corrosion of catalyst at long-term operation, and thus, ultimately evaluate their implementation to valorize intermittent electricity.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501583"},"PeriodicalIF":6.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145190559","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}
