This review comprehensively examines the advancements in methanol oxidation, categorizing the processes into complete oxidation (MOR) and selective oxidation (MSOR). MOR facilitates the total conversion of methanol into CO2 and H2O, while MSOR aims to produce valuable formate, which can enhance energy conversion efficiency and contribute to the synthesis of high-value chemicals. The review highlights the critical role of catalysts in these processes, detailing the progress in designing and optimizing various catalyst classes, including precious metals, transition metal oxides, and non-precious metal-based catalysts. Recent innovations in catalyst design, such as the use of nanostructured materials and hybrid systems, have shown promise in improving reaction rates and selectivity. Despite significant advancements, challenges remain, particularly in achieving high activity, selectivity, and stability under operational conditions. Future research directions are identified, emphasizing the need for scalable catalyst production and integration of methanol oxidation processes into existing energy infrastructures. This review underscores the importance of methanol oxidation in the broader context of energy conversion and storage, paving the way for the development of more efficient and sustainable energy systems.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402767"},"PeriodicalIF":7.5,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522169","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}

Medium- and long-chain ALs (pentyl levulinate or longer) have shown potential as biofuel and fuel additives due to their relatively low oxygen content and resemblance to biodiesel. This study reports a fast and environmentally friendly method for synthesizing ALs via microwave (MW)-assisted LA esterification, laying emphasis on medium- and long-chain ALs. By combining p-toluenesulfonic acid (5 wt% loading) as catalyst and MW radiation as heating source for a short time (5 minutes), excellent yields of ALs (≥ 89 mol%) were achieved for a wide range of primary and secondary alcohols (2-10 carbons), overcoming the expected lower reactivity of long chain alcohols. Additionally, formation of undesired side products, such as dialkyl ethers of LA aldol condensation products, was significantly minimized. The feasibility of recovering the unreacted alcohol was successfully proved by simple distillation (88 wt% recovery). The green chemistry metrics assessment proved that this approach aligns with the green chemistry principles and the United Nations Sustainable Development Goals, offering a more sustainable pathway for biofuel and fuel additive production.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402508"},"PeriodicalIF":7.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497580","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, maintaining its pure β-phase during fabrication remains a significant challenge, as phase instabilities often degrade its thermoelectric performance. Here, we demonstrate the successful optimization of β-Zn4Sb3 thin films through controlled Sn doping using ion beam-assisted deposition. By precisely regulating the Sn concentration at 0.97 %, the β-Zn4Sb3 phase is preserved, resulting in a maximum power factor of 1.4 mW m-1 K-2 at 573 K-a 60 % improvement over undoped films. Comprehensive analyses reveal that dilute Sn doping enhances carrier mobility and structural stability while avoiding detrimental phase transitions to ZnSb. These findings highlight the importance of precise doping and processing control in stabilizing the β-phase structure. This work provides a new pathway for fabricating high-quality thermoelectric thin films, offering valuable insights into the development of scalable, efficient energy harvesting technologies.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402690"},"PeriodicalIF":7.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143490211","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, we address this issue by developing an innovative, eco-friendly method to achieve superhydrophobicity using SCG. Repurposing this abundant biowaste, we developed a sustainable approach that avoids the use of harsh chemicals and energy-intensive processes typically associated with conventional methods. Our procedure involves wet ball milling of SCG in ethanol to produce microparticles, followed by electrospraying to create a micro-structured interface. A mild annealing treatment at 90 °C successfully transformed the SCG interface from hydrophilic to superhydrophobic, reaching a contact angle of approximately 151° and a rolling-off angle of 8°. The resultant interface exhibited remarkable self-cleaning properties, effectively repelling various liquids. XPS analysis revealed that the migration of fatty acids to the surface during annealing played a crucial role in lowering surface energy, thereby driving the hydrophilic-to-superhydrophobic transition. Furthermore, we demonstrated that solar-induced heating can effectively activate the same superhydrophobic properties, providing a practical and energy-efficient alternative to traditional thermal treatments. This method illustrates the role of light-activated fatty acid modulation in achieving superhydrophobicity and highlights the potential of SCG biowaste as a valuable resource for sustainable material applications.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402254"},"PeriodicalIF":7.5,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481933","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 wine industry is one of the pillars of Italian agri-food sector. Nevertheless, large quantities of by-products such as grape stems are produced, which are usually disposed of at a cost, and therefore represent an attractive negative-cost feedstock for biorefinery. In this work, a sequential protocol for biomass valorization is proposed, characterized by a multidisciplinary strategy using enabling technologies and subcritical water as a green solvent, where physical/chemical treatments synergistically interact with biological treatments. The first phase involved the sequential fractionation of grape stalks, obtaining several product streams rich in polyphenols, hemicellulose, pectin (13.15 % of cumulative yield on biomass), lignin and cellulose. A membrane treatment was employed to recycle materials within the process. Finally, the cellulose-rich residue was exploited as a fermentation substrate for the last step, producing up to 5.8 g/L of lactic acid by harnessing suitably engineered Clostridium thermocellum strains. The polyphenolic fraction successfully inhibited the growth of Brettanomyces bruxellensis and Acetobacter pasteurianus, microorganisms responsible for major wine off-flavors. Globally, this study represents a proof-of-concept of a second-generation biorefining process based on locally available waste biomass.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402536"},"PeriodicalIF":7.5,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143381335","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}
