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}

Here, the synthesis, structural chemistry, and spectroscopic properties of a neodymium-acetylacetonate monomer, [Nd(acac)3(H2O)2] (Nd-1), and an acac-bridged Nd-dimer, [Nd2(acac)6(H2O)2] (Nd-2), are described. Interestingly, the Nd-dimer readily precipitates from solution; however, efforts to crystallize the Dy analog using the same synthetic approach are unsuccessful. Yet heterometal dimers, [Nd2-xDyx(acac)6(H2O)2] (NdDy-2), can be prepared from mixed-metal solutions. To understand these differences in crystallization behavior of Nd- and Dy-acac complexes, solution speciation of Ln-acac systems is examined using nano-electrospray ionization-mass spectrometry (nESI-MS). Both homometal and heterometal solutions are prepared (Ln = Nd, Dy, Nd/Dy). nESI-MS of the solutions showed presence of homometallic dimeric species for Nd and Dy and peaks consistent with both homometallic and heterometallic complexes in mixed-metal solutions. Density functional theory is used to further understand the intrinsic differences in nucleation energetics in dimeric homo- and heterometallic species. Overall, this work provides fundamental insight into the correlation between solution- and solid-state structural units and differences in the crystallization behavior of Ln complexes; the latter is particularly relevant to separating metal ions with otherwise very similar chemical behavior.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 16","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202500171","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144220236","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}

Additionally, density functional theory and time-dependent density functional theory calculations are conducted to extract key structural, electronic, and excited-state properties. The catalytic performance of these Fe(II) complexes in the CRP2 of methyl acrylate (MA) is evaluated under different conditions, using ethyl α-bromophenylacetate as the initiator and triethylamine as the electron donor. The photopolymerizations proceed efficiently, yielding polymers with controlled molecular weights and narrow molecular weight distributions.

The OER performance of many semiconducting metal oxide catalysts is hindered by weak charge separation at the interface, fast carrier recombination, low electrical conductivity, and lack of adsorption properties. A promising approach to overcome these issues is the integration of OER catalysts with porous and highly conductive semiconductor templates. However, the strategic selection of the template is important to facilitate the formation of heterojunction, which can promote effective carrier transport and boost photoelectrochemical performance. Herein, a novel binder-free photoelectrocatalyst for efficient alkaline water oxidation is reported. This catalyst is developed through an in situ incorporation of OER active nickel oxide (NiO) catalyst into a porous, conductive antimony-doped tin oxide (ATO) semiconductor using a resorcinol-formaldehyde polymer supported sol–gel method. The prepared NiO/ATO binder-free porous catalyst exhibits greatly improved photoelectrochemical performance toward water oxidation with a remarkable low onset potential of 1.39 V and an overpotential of 282 mV (at 10 mA cm−2).
