This study presents a green strategy for extracting lignin with enhanced photothermal performance from wood using molten salt hydrate (MSH) and citric acid under mild conditions. Systematic investigations revealed that elevated reaction temperatures (170°C) promoted lignin depolymerization (Mw=1206) and increased phenolic hydroxyl content (3.5 mmol/g), enhancing π-π stacking interactions to achieve a photothermal conversion efficiency of 36.31%. Structural analyses through 2D-HSQC NMR confirmed β-O-4 bond cleavage and demethylation, while fluorescence quenching validated reduced radiative losses. Leveraging this lignin, a gradient evaporator was fabricated by integrating polyvinyl alcohol (PVA)-modified melamine foam (MF) with a hydrophobic lignin-polyvinylidene fluoride (PVDF) photothermal layer. The evaporator exhibited hierarchical wettability, enabling gravity-guided water transport (2.8 kg m-2 h-1) under 0.1 W/cm²) and environmental heat harvesting. It demonstrated robust performance in hypersaline water (1.85 kg m-2 h-1 for 10.5 wt% brine) and dye removal (>99.98% rejection). Additionally, lignin-coated thermoelectric devices generated stable power (27.69 W/m²) via solar-thermal conversion. This work provides an eco-friendly pathway for lignin valorization and scalable solar evaporation systems, addressing energy-water challenges through biomass resource utilization.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500538"},"PeriodicalIF":7.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750643","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 issue is particularly pressing for polyoxymethylene (POM), a widely used engineering thermoplastic known for its exceptional mechanical properties and durability, which degrades slowly and releases harmful formaldehyde (HCHO). In this study, we present a straightforward method to convert POM waste into formic acid (FA) using hydrogen peroxide (H2O2) as the oxidant. While H2O2 is recognized as a selective and mild oxidation agent, its potential for upcycling plastics into valuable chemicals has been largely uncharted. Our approach utilizes microporous aluminosilicate zeolite H-Beta, known for its Brønsted acidity, to effectively catalyze both the depolymerization of POM into HCHO and its subsequent oxidation to FA. A significant aspect of this method is the incorporation of 1,1,1,3,3,3-hexafluoroisopropanol, which enhances depolymerization through strong hydrogen bonding interactions. This catalytic system efficiently transforms a variety of post-consumer POM waste into FA while also facilitating the Baeyer-Villiger-type oxidation of various carbonyl compounds, achieving high yields in both processes. Overall, these findings advance the conversion of plastic waste into value-added chemicals via H2O2-mediated reactions, enhancing sustainable waste management and supporting circular economy principles.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500179"},"PeriodicalIF":7.5,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750657","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}

Despite growing interest, the development of scale-up strategies for redox-ED remains limited, delaying its industrial implementation. This study proposes a scale-up strategy by examining the impact of stacking electrodes and channels on the desalination performance of the system, aiming to enable economically viable desalination. The results show that electrode and channel stacking (up to three stacks) significantly enhances desalination performance, resulting in a 6.8-fold increase in the salt removal rate, and a 30% improvement in productivity. These enhancements can be attributed to synergistic effects of electrode and channel stacking, which improve the redox reaction rate by increasing the surface area and enhancing the system capacity by increasing the volumetric flow rate. Technoeconomic analysis underscores the economic viability of the scale-up strategy proposed in this study, showing 18% and 32% reductions in capital and operating costs, respectively, compared with multiple unit cell systems. Overall, incorporating multiple stacks of electrodes and channels offers an effective strategy for scaling up redox-ED systems with high economic viability, thereby providing a pathway for their industrial utilization.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2500452"},"PeriodicalIF":7.5,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750647","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}

For the bio-lubricant production, catalytic routes involve C-C coupling reactions, followed by hydrodeoxygenation (HDO) or hydrogenation reactions to produce hydrocarbons. For the lubricant production from polyolefin plastic wastes, catalytic strategies include pyrolysis followed by hydroconversion or direct hydrogenolysis. Various strategies along with their respective catalysts, are exemplified. The performance and mechanisms of catalysts for each reaction are systematically summarized. Additionally, the structure-property relationships of lubricant molecules are comprehensively discussed to gain the guidance for the design of superior lubricant architectures. Technoeconomic analysis and life cycle assessment are also addressed to evaluate commercial viability and environmental impact. Finally, perspectives on future developments in this field are offered.

In KOH and artificial seawater, Fe-CW demonstrates overpotentials of merely 38 and 94 mV at 10 mA cm-2, accompanied with excellent stability. For the anodic counterpart, OER is replaced with the 5-hydroxyfurfural oxidation reaction (HMFOR) using Fe/NiB/CF catalyst. It achieves an oxidation potential of 1.46 V to attain 100 mA cm-2 for HMFOR and convertes 5-hydroxyfurfural to 2,5-furandicarboxylic acid with a remarkable conversion rate of approximately 100%.

Phase change materials (PCMs) have emerged as a pivotal technology in the urgent transition toward carbon neutrality, especially considering that heating and cooling consume nearly half of global energy expenditure. This comprehensive review advances the scientific understanding of sustainability and circularity in PCM fabrication by providing a strategic framework for developing composites from renewable resources. This framework involves the introduction of a novel classification system (Types 0-3) for biomass-derived PCMs based on their levels of modification, enabling a comparison of material sources, performance metrics, and environmental impacts. By showing recent innovative developments in PCM shape stabilization, thermal conductivity enhancement, and leakage protection, it critically highlights the opportunities to replace conventional materials with innovative biomass-derived alternatives, such as biomass-derived carbons and polymers. Furthermore, the study integrates tools aligned with the Principles of Green Chemistry to aid the fabrication of truly sustainable materials, helping to guide researchers through material selection, process optimization, and the comprehensive evaluation of the environmental impact associated with their use and disposal.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500288"},"PeriodicalIF":7.5,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143727292","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}
