In this paper, a copper-based MOF: {[Cu·(L)·(H2O)]·(DMF)}n (1) (H2L = 2-hydroxyterephthalic acid; DMF = N,N-dimethylformamide), was synthesized by hydrothermal synthesis method. X-ray single crystal diffraction showed that a two-dimensional structure was formed by the carboxyl group of L2- in 1 took μ2-η1：η1 bridged two adjacent Cu(II). In this two-dimensional structure, the coordinated water molecules and hydroxyl group on L2- were distributed on the surface of 1. Thus, it had abundant adsorption sites. The transmission electron microscopy (TEM) of copper-based MOF nano adsorbent showed that the particle diameter of the nano adsorbent prepared by a cell fragmentation apparatus was about 50 nm. The performance of the copper-based MOF nano adsorbent in adsorbing MB indicated that the optimal adsorbent dosage was 0.20 g/L and the solution pH was 6. Under the optimal experimental conditions, its maximum adsorption capacity for MB was 143.3 mg/g, which was superior to most MOFs adsorbents. The adsorption thermodynamic analysis showed that the copper-based MOF nano adsorbent at 25 - 45 ℃ was an exothermic (△H < 0) , and spontaneous (△G < 0) process.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.524,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141257276","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}

The ligands' effects on the metal center and the factors determining regioselectivity in chiral tertiary amine formation were examined. The computational results revealed that the oxidative quenching process involved in the photocatalytic redox cycle via Cu I-Cu I*-Cu II-Cu III transitions. Throughout the reaction, four key processes occurred: C-Br bond activation, ligand exchange, amide ion/Br ion exchange, and C-N coupling. Among these steps, alkyl radical generation through single electron transfer was identified as the rate-determining step with an energy barrier of 13.9 kcal/mol. The chelating diphosphine ligand improved copper's reducibility and its capacity to activate the C-Br bond by charge transfer when exposed to visible light (CT). Copper's own redox process was facilitated by interactions between diphosphine and diamine ligands. Finally, when combined with oxygen, this catalyst system formed a chiral plane Cu II-O 1-N 1-N 2-N 3 essential for enantioselective product formation.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.524,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141257012","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}

For one synthesis method of ε‐Fe2O3, combining reverse‐micelle and sol‐gel techniques, Ba ions are used to accelerate the formation of nanorod‐shaped ε‐Fe2O3. On the other hand, in synthesis of BaFe12O19 both Ba and Fe ions are used to form the final product. However, the coexistence of these two ferrites has not been reported by any synthesis. Herein, we investigated the effect of Ba ions on the final product for the synthesis combining reverse‐micelle and sol‐gel techniques. At a low Ba ion ratio of [Ba]/[Fe]=0.2, ε‐Fe2O3 nanorods are formed, while at higher Ba ion ratios ([Ba]/[Fe]= 0.4, 1, 2), BaFe12O19 appears. The phase diagram at 1000 °C shows that at a Ba ion ratio of [Ba]/[Fe]= 1, the ratio of ε‐Fe2O3 and BaFe12O19 is almost 1:1. The diagram shows intermediates between these two phases do not form, indicating a phase separation of ε‐Fe2O3 and BaFe12O19. During the sintering process of this synthesis, initially perovskite‐type Ba2Fe2O5 and γ‐Fe2O3 nanoparticles form. Then, in areas where γ‐Fe2O3 nanoparticles are gathered around Ba2Fe2O5 and react, BaFe12O19 is formed, whereas in areas lacking Ba2Fe2O5, ε‐Fe2O3 nanorods are formed within Ba‐ion containing silica glass.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.524,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141188888","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}

We report the development of highly active, robust and magnetically separable Ni2MnAl Heusler alloy nanoparticles as a heterogeneous catalyst for hydrogenation of aliphatic and aromatic nitro compounds to the corresponding amines. The easily synthesizable Ni2MnAl nanoparticles are thermally and chemically robust and exhibited excellent chemoselectivity in the hydrogenation of a range of aliphatic and aromatic nitroarenes, including those bearing functional groups sensitive to reduction, such as alkene, bromo, iodo, carbonyl and cyano, yielding the respective functionalized amines in good yields. Moreover, this solid catalyst is magnetically separable from the reaction mixture and could be recycled and reused at least 10 times without any loss in catalytic activity. The mechanism of the Ni2MnAl Heusler alloy nanoparticles catalyzed nitro reduction was studied by various spectroscopy and control experiments and kinetics. Our work opens a new avenue of developing heterogeneous earth‐abundant metal catalysis for economic and environment‐friendly synthesis of fine chemicals owing to their straightforward synthesis and tunable composition from base‐metals and their diverse structure and properties with their high surface area, thermal and chemical stability, excellent chemoselectivity, magnetic separability and recyclability.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.524,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141188896","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}

This catalyst capitalize on the NIR absorption capabilities of Bi12CoO20 and the electron transfer properties of reduced graphene oxide (rGO). The restored sp2 structure of rGO serves as a conduit for electron transfer, crucial for the redox cycle of Co2+/Co3+ that facilitates PMS activation. Moreover, the incorporation of rGO significantly boosts the NIR absorption capacity of Bi12CoO20, thereby enhancing the photothermal conversion efficiency of the composite and further promoting PMS activation. This synergy enables efficient light-to-heat conversion and PMS activation, generating reactive oxygen species (ROS) essential for antibiotic degradation. Using levofloxacin (LVX) as a representative pollutant, the developed system achieves an impressive 99% degradation rate within just 30 min under Bi12CoO20/rGO + PMS + NIR conditions. Moreover, this approach demonstrates robust stability and adaptability across diverse water compositions and pH ranges. Its eco-friendly nature and renewable characteristics position it as a promising solution for combating antibiotic pollution through photothermal Fenton-like technology, thereby harnessing solar energy for environmental remediation and fostering sustainable water management practices.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.524,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141168999","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}
