Abstract

The synthesis of a trinuclear Co(II)-based coordination polymer (CP), [Co₃(HL)₂(H₂O)₆·2.2H₂O]_n (1), was achieved via a solvothermal method involving CoCl₂·6H₂O and 3-(2,4-dicarboxylphenyl)-2,6-dicarboxylpyridine (H₃L). The photocatalytic efficiency of the complex was evaluated for the degradation of various antibiotics ornidazole (ODZ), nitrofurantoin (NFT), dinitroaniline (DNZ), and tinidazole (TDZ) in wastewater. Notably, NFT exhibited a remarkable 91.5% degradation within 20 min under optimal conditions. The catalytic performance was influenced by the amount of photocatalyst, NFT concentration, and solution pH, with optimal conditions identified at 6-mg catalyst dose, 30 mg/L NFT concentration, and pH 7. Trapping experiments highlighted the roles of superoxide and hydroxyl radicals as primary active species in the photocatalytic process. Furthermore, the magnetic behavior is also discussed in detail.

构建新型二维配位聚合物：降解抗生素硝基呋喃妥因和磁性

通过 CoCl2-6H2O 和 3-(2,4-二羧基苯基)-2,6-二羧基吡啶 (H3L) 溶剂热法合成了一种基于 Co(II) 的三核配位聚合物 (CP)--[Co3(HL)2(H2O)6-2.2H2O]n (1)。评估了该复合物在降解废水中各种抗生素奥硝唑（ODZ）、硝基呋喃妥因（NFT）、二硝基苯胺（DNZ）和替硝唑（TDZ）时的光催化效率。值得注意的是，在最佳条件下，NFT 在 20 分钟内的降解率高达 91.5%。催化性能受光催化剂用量、NFT 浓度和溶液 pH 值的影响，最佳条件为 6 毫克催化剂用量、30 毫克/升 NFT 浓度和 pH 值为 7。捕集实验强调了超氧自由基和羟基自由基作为光催化过程中主要活性物质的作用。此外，还详细讨论了磁性行为。

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
