Herein, an entropy-driven multi-anionic ether electrolyte (HE-DIG) is designed to alleviate the abovementioned problems. Theoretical computations elucidate that multi-anion coordination in HE-DIG facilitates the formation of weakened solvation structures while concurrently expanding electronic bandgaps. This synergistic modulation significantly mitigates limitations imposed by Li+ desolvation kinetics at low temperatures and effectively suppresses oxidative decomposition under high-voltage conditions. As expected, LiNi0.52Co0.2Mn0.28O2 (NCM523) in HE-DIG exhibits higher capacity, stable median voltage and better cycling performance than commercial ester electrolytes at both 25 °C and −20 °C. The preferential decomposition of LiNO3 and LiDFOB generates a cathode−electrolyte interphase (CEI) rich in inorganic species. In addition, Li1.2Ni0.2Mn0.6O2 (LNMO) displays superior long-term cycling stability, retaining 83.8% capacity after 1000 cycles at −20 °C in HE-DIG. Remarkably, a 12 A h pouch cell with a graphite anode, NCM523 cathode, and the HE-DIG electrolyte delivers outstanding cycling stability, maintaining 91.6% capacity after 800 cycles at a rate of 8C. This work provides a solvation-tuning strategy leveraging anion diversity for advanced battery systems.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 25","pages":" 7704-7716"},"PeriodicalIF":9.3,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339064","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}

Silica fume, a by-product of industrial silicon and ferrosilicon alloy production, represents a hazardous waste with limited recycling options. In this study, sodium silicate synthesized via alkali dissolution was used as the starting material. High-purity silica powder was obtained by employing calcium oxide for impurity removal followed by a carbonation process. A single-factor experiment revealed that, under conditions of 60 °C, a reaction time of 3 h, and 6 g L−1 calcium oxide, the removal rates of aluminum and iron were 50.2% and 91.4%, respectively. Optimization using response surface methodology enhanced aluminum removal to 53.1%, while iron removal remained at 91.5%. In the carbonation experiment, conducted at 75 °C, with a pH of 9.0, a concentration of 60 g L−1, a CO2 flow rate of 40 mL min−1, and a stirring speed of 300 rpm, the silica recovery rate reached 92.4%, and the agglomerate particle size was 11.38 μm. Characterization techniques including XRD, FTIR, SEM, and XRF confirmed that the product was 99.79% pure amorphous silica. After further treatment with chelating agent purification and mixed acid leaching, the purity of the synthesized silica can reach 99.9914% (4N). This process offers significant environmental and economic benefits by recycling silicon-containing waste and reducing CO2 emissions.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 7191-7207"},"PeriodicalIF":9.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291823","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}

However, conventional synthetic approaches for MTV-MOFs—primarily relying on thermal reactions or limited room-temperature (RT) protocols—face challenges in achieving optimal functional diversity and application-specific performance. Here, we report a green, RT synthesis strategy for MTV-MOF-801 derivatives incorporating mixed fumarate/aspartate linkers. Systematic investigations have revealed that pore architecture can be finely tuned by modulating the fumarate/aspartate ratio, enabling dynamic structural adaptability to external stimuli. Furthermore, replacing Zr6 clusters with Ce6 clusters in the MOF-801 framework markedly enhances its capacity to integrate flexible aspartate ligands while improving the separation efficiency for CO2/N2 mixtures and C6 isomers. These results underscore the synergistic role of linker composition and metal-node substitution in property optimization. The RT-driven methodology demonstrated here provides a sustainable and versatile pathway for designing advanced MTV-MOFs with enhanced functionality for gas separation and beyond.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 25","pages":" 7642-7651"},"PeriodicalIF":9.3,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339011","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}

Here, we present eSpiro, a novel electrosynthetic method for the efficient and sustainable synthesis of spiroketals via anodic oxidation of malonic acids. This approach offers a metal- and mercury-free alternative to conventional acid-catalysed or transition metal-mediated cyclisations. The reaction proceeds through a sequential Hofer-Moest decarboxylation, followed by Brønsted acid-mediated cyclisation, achieving high yields with broad functional group tolerance. We further explore the reaction scope and demonstrate its scalability, achieving up to 98% yield in batch. Additionally, we investigate a flow electrolysis setup, highlighting key challenges such as substrate stability, in-line solvent system switch and gas evolution, and also demonstrating preliminary success in integrating electrochemical oxidation with downstream acid-catalysed cyclisation. This work provides a practical and eco-friendly route to spiroketals, with potential for industrial applications in organic synthesis.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 25","pages":" 7513-7517"},"PeriodicalIF":9.3,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339056","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}

Here, we report the discovery of native genistein biosynthesis in the Paenibacillus jilinensis, which inherently produces 5.7 mg L−1 genistein via the phenylalanine branch of the phenylpropanoid pathway. This pathway mirrors plant flavonoid synthesis but operates through seven bacterial enzymes (PjPAL, PjC4H, Pj4CL, PjCHS, PjCHI, PjIFS, and PjHID) with about 30% sequence homology to the corresponding protein sequences in plants, suggesting evolutionary convergence. To leverage this native capability for sustainable production, we constructed a genome-scale metabolic model (GSMM YPG26) with 1636 reactions and 717 genes to rationally optimize carbon flux. Metabolic engineering elevated genistein titers by 9.3-fold to 52.8 mg L−1 without introducing heterologous plant genes. Green-chemistry analysis further showed that P. jilinensis-ΔGLN achieves 92% less waste than soybean extraction and up to one order of magnitude better than state-of-the-art E. coli and yeast systems. It is crucial that this bacterial platform requires only a basic culture medium for sustained production, and eliminates dependence on medicinal plants. Our findings reveal P. jilinensis as a naturally gifted genistein producer and a green chassis for industrial isoflavone synthesis, aligning with green chemistry goals of waste prevention and bio-based process innovation.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 25","pages":" 7575-7585"},"PeriodicalIF":9.3,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339000","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}

HTL is generally preferred for wet biomass, while fast/flash pyrolysis is more suitable for dried biomass, as moisture content plays a crucial role in determining the appropriate conversion method. Beyond moisture content, the biochemical and elemental composition of biomass significantly impacts the physical and chemical characteristics of the resulting liquid biofuels, often increasing the need for upgrading. This review provides a comprehensive comparison of HTL and fast/flash pyrolysis for converting five biomass types—lignocellulosic biomass, microalgae, macroalgae, municipal sludge, and food waste—into liquid biofuels, highlighting the impact of biomass composition on biofuel yield and quality. By linking biomass type, process severity, and liquid biofuel quantity, this study offers a structured framework for selecting the optimal conversion process and severity range to maximize biofuel yield in large-scale applications. Additionally, this review identifies various organic compounds and their concentrations in liquid biofuels produced through HTL and fast/flash pyrolysis from different biomass sources, serving as a valuable resource for developing novel multistage and selective upgrading processes.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 7009-7041"},"PeriodicalIF":9.3,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/gc/d5gc01314c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
