Vanadium-based materials, including vanadium oxides, vanadium sulfides, vanadate, and vanadium carbon composites, have gained attention for their diverse crystal structures, multiple oxidation states, and high theoretical capacities. This review summarizes recent advances in vanadium-based cathodes, focusing on structural design and modification strategies, such as amorphous structures, defect engineering, conductive carbon matrices, and cation pre-intercalation to enhance Zn2+ storage. Vanadium oxides and vanadium sulfides offer unique ion diffusion advantages, while vanadate and vanadium carbon composites improve conductivity and stability. Vanadate is highlighted as a critical approach to reduce electrostatic repulsion and facilitate Zn2+ storage. Vanadium carbon composites (V-MOF derivations, vanadium oxides @ carbon, combined with graphene and conductive polymer) have unique advantages in terms of conductivity, ion diffusion, and structural stability. Emerging materials like VN, VOPO₄ and V2CTx are also discussed. Future directions include multi-guest doping, anion pre-intercalation, and advanced carbon integration. This review aims to guide the development of high-performance AZIBs and inspire future research in this field.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202500219"},"PeriodicalIF":3.9,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530846","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 the first step, the polyunsaturated esters of the RME were semi-hydrogenated in the presence of 20 ppm of a solvent-stabilized Pd0 colloid. The resulting mono-unsaturated fatty esters were further converted into a defined mixture of double-bond isomers by passing them over inexpensive, Brønsted-acidic Amberlyst resin at high space-time yields (1.3 kg·L-1·h-1). The resulting mixture was then converted into a blend of terminally unsaturated olefins and monoesters, with <4.9% diesters and <21% saturated fatty esters by cross-metathesis with technical-grade ethylene. In this step, 50 ppm of a cyclic alkyl amino carbene (CAAC) Ru catalyst M1001 was used to achieve record-setting conversions (91%) and selectivities (94%). All three steps were conducted with neat feedstock at mild temperatures (60-100 °C). This demonstrates that sustainable diesel fuel for use in contemporary diesel engines is accessible from RME and ethylene via a short set of industrially viable reaction steps.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202500523"},"PeriodicalIF":3.9,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522386","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 the development of various methods for vicinal amino alcohol synthesis, C(sp3)-rich oxygen-containing β-amine compounds continue to pose great challenge. While ring-opening reaction of epoxides with amine nucleophile is the prime method for vicinal amino alcohol preparation, epoxides are highly reactive and sometimes difficult to make, resulting in drawbacks regarding selectivity of this approach. Here, we report a catalytic enantio-convergent amination of α-tertiary 1,2-diols for the efficient access to vicinal amino α-tertiary alcohols. The racemic α-tertiary 1,2-diol substrates of different alkyl/aryl or alkyl/alkyl backbone, can be converted to chiral vicinal amino a-tertiary alcohols through diphenyl phosphate-mediated RuCl3 catalysed asymmetric borrowing hydrogen (ABH) pathway. This simple ABH reaction can be scaled up to the synthesis of chiral ligands, synthetic intermediates, and other medicinally-relevant compounds. Overall, this catalytic redox-neutral procedure broadens the scope of Ru-catalysed amination of alcohols and discloses an underexplored step- and atom-economical synthetic strategy for the synthesis of vicinal amino α-tertiary alcohols and provides a practicable alternative to the present benchmark procedures.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202404152"},"PeriodicalIF":3.9,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143514193","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}
