Herein, an efficient and novel strategy based on sulfur-assisted phase transformation followed by water leaching has been proposed to selectively extract Li from spent SSBs. Structural characterization indicates that the substitution of sulfur for oxygen in dodecahedral [LaO8] can promote the collapse of the garnet structure, and the Li in the crystal lattice can be fully converted into water-soluble Li salts. Under optimized conditions, the recovery ratio of Li can be as high as 99.6% with Li leaching selectivity approaching 100%. The techno-economic analysis demonstrates that the sulfur-assisted phase transformation for the selective recycling strategy holds potential economic and environmental value in battery recycling. Additionally, the lithium extraction slag can be transformed into a highly efficient solid electrolyte sintering aid through secondary roasting, which enables the SSBs to show greatly enhanced cycling stability and rate performance via increasing the densification of the solid-state electrolyte and improving the ionic conductivity. This work offers fresh insights into recycling spent SSBs and advancing the applications of SSBs.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 29","pages":" 8950-8958"},"PeriodicalIF":9.3,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144671954","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}

Previous studies showed that commercial TiO2 effectively cleaved α-O-4 linkages, but 4-O-5 linkages were much harder to break due to higher bond energy. Here, we successfully synthesized mesoporous TiO2 with a high specific surface area, while oxygen vacancies enhanced its visible light absorption and regulated the position of the energy band. Additionally, the Z-scheme heterojunction Pt@CDs-2/TiO2-MP was successfully prepared by introducing carbon dots, thereby effectively promoting the separation and transfer of photogenerated hole–electron pairs. Pt@CDs-2/TiO2-MP was employed for the cleavage of 4-O-5 type lignin model diphenyl ether (DPE), with DPE being almost completely converted under 365 nm LED irradiation and achieving a 90.0% conversion rate under visible light. Besides, Pt@CDs-2/TiO2-MP effectively cleaved α-O-4 (benzyl phenyl ether, 77.8%) and β-O-4 (phenethoxybenzene, 99.6%) models. Even for the C–C bond with a high dissociation energy (biphenyl, 99.0%), it exhibited significant bond cleavage capability, achieving a cyclohexane yield of 10.0%. Furthermore, this photocatalytic method successfully converted different types of lignin into high-value aromatic monomers. This study presents a sustainable and efficient method for the conversion of lignin, thereby contributing significantly to the achievement of sustainable development goals.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 29","pages":" 8883-8900"},"PeriodicalIF":9.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144671929","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}

The HDO process typically involves the use of high-pressure molecular hydrogen, which poses safety concerns and lacks sustainability. Herein, we report an effective catalytic approach that integrates the aqueous-phase reforming (APR) of ethanol with the selective HDO of lignin-derived phenol to benzene over a well-defined Pt/Al2O3 catalyst. The effects of catalyst support, ethanol-to-water ratios, and reaction temperatures on in situ HDO processes were systematically explored and thoroughly discussed. The competitive routes of C–O bond hydrogenolysis and benzene ring hydrogenation during HDO of phenol were found to be significantly dependent on the H2 produced by the APR of ethanol and variations in reaction parameters. A lower H2 pressure, generated from an optimized Vethanol/Vwater of 3 : 5 and a high reaction temperature of 280 °C, favored the selective cleavage of C–O bonds rather than the hydrogenation of benzene rings, resulting in a relatively high phenol conversion of ca. 57% with a benzene selectivity of ca. 97% after 2 h of reaction. The proposed reaction pathways involved in the currently developed in situ HDO process provided a deep understanding of the pronounced selectivity towards benzene formation from phenol under optimized reaction conditions. The conversion of other representative lignin-derived phenolics and ethers further validated the superiority and versatility of the developed catalytic system in producing aromatic compounds from lignin biomass.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 29","pages":" 8959-8971"},"PeriodicalIF":9.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144671955","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}

The bi-functionalized chemocatalyst (Au@HS/SO3H-DON), which possesses both Au NPs and Brønsted acid catalytic sites, exhibits superior catalytic performance and better reusability compared to those of homogeneous Au(III) catalysts. The bi-functionalized biocatalyst (ADH@QA-DON) exhibits enhanced reusability over free ADH and enriches NADH, enhancing the overall catalytic performance. Various chiral alcohols are directly obtained from alkynes with high yields (73%–92%) and enantioselectivity (>99% ee) via tandem cascade reactions catalyzed by bifunctional chemo- and biocatalysts.

This review critically evaluates conventional photocurable formulations, highlighting the limitations of standard metrics such as the biobased carbon content (BCC%), and introduces the sustainable formulation score (SFS) as a comprehensive alternative. By integrating factors like atom economy, hazardous reagent usage, solvent selection, and end-of-life considerations, SFS offers a more holistic measure of environmental impact. The analysis encompasses diverse resin systems, including (meth)acrylated vegetable oil derivatives, biobased small molecules from lignin and other renewable sources, non-isocyanate urethanes, and thiol–ene formulations. For vegetable oil-based systems, a key trade-off is observed between achieving high biobased content and maintaining optimal mechanical properties, driven by variations in the degree of acrylation and processing conditions. In contrast, the synthesis of small biobased molecules often involves toxic reagents and less favorable atom economies, reducing their overall green appeal. Moreover, non-isocyanate urethanes and thiol–ene systems emerge as promising routes for improving sustainability while preserving performance. Overall, this review underscores the need for unified green metrics and optimized synthesis strategies to bridge the gap between environmental sustainability and material performance in photopolymer formulations, paving the way for more responsible and efficient additive manufacturing technologies.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 29","pages":" 8710-8754"},"PeriodicalIF":9.3,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/gc/d5gc02299a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144671292","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}
