In this context, a strongly HDES based on trioctylphosphine oxide and decanoic acid is employed in its undiluted condition for the solvent extraction of Eu(III) (taken as Ln(III) representative) from a broad range of nitric acid solutions. The projected HDES is highly hydrophobic and less viscous in nature. Various solvent extraction parameters are tuned to realize the extractant behavior of the proposed HDES. Though the extraction shows a decline at high feed acidity, the system is efficient to extract Eu(III) from pH range to concentrated acid solution with a high % extraction. The involvement of two HDES in the metal–solvate species (metal–ligand complex) formation with fast extraction kinetics corroborates the suitability of the extractant for extracting Eu(III) from the acidic phase. The phase volume ratio is changed to affirm the best possible extraction factors at the expense of minimum volume of HDES. The stripping performance of Eu(III) from the loaded HDES phase is investigated using Milli-Q water as the stripping solution, thereby establishing the sustainability of the system.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 15","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, partial substitution of zirconium (Zr4+) into the octahedral Fe site of CoFe2S4 is explored to enhance its electrocatalytic performance. The structural and electronic characterization reveals that Zr4+ incorporation induces lattice distortion and modulates the electronic environment, resulting in an enhanced charge distribution. Notably, the optimized Zr-doped catalyst (Zr0.1CFS/N-RGO) exhibits a significantly improved oxygen evolution reaction performance, achieving a low overpotential of 470 mV at 10 mA cm−2 and a small Tafel slope of 55 mV dec−1 in 1 M KOH. Furthermore, the catalyst demonstrates remarkable durability, retaining 91% of its initial current density after 12 h of continuous operation. These findings underscore the potential of strategic transition metal doping to optimize nonprecious metal-based catalysts for sustainable electrochemical water splitting applications.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 14","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144131581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, melam's ability to act as a bidentate ligand has hardly been explored so far. The main focus of this work was therefore to advance the knowledge about melam's coordination chemistry by the synthesis of its complexes with CuCl, CuBr, CuI, CuCN, and AgCl as well as their structural characterization by single crystal and powder X-ray diffraction. Their crystal structures were found to feature channels along the molecules’ stacking direction. It was further shown that these melam complexes have excellent hydrolytic and thermal stability, making them potentially interesting for heterogeneous catalysis in aqueous media either as promising precursors for polymeric carbon nitrides or possibly already on their own, especially since it should be possible to fine-tune properties by preparing solid solutions of these melam complexes, which was exemplarily demonstrated between the CuBr and CuI derivatives. Additionally, the crystal structure of melam's HCl salt was elucidated, which proved to be closely related to that of the coordination complex between melam and CuCl, underlining the similar chemical behavior of Cu+ and H+ toward melam.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 15","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202500240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
