摘要

基于[Re(吡啶基-三唑)(CO)3Cl]的光催化二氧化碳还原（PCO2R）在各种介质中得到了验证，在低强度可见光照射下，以三乙醇胺（TEOA）和水为电子供体（ED）。在 DMF-TEOA（DMF：N, N'-二甲基甲酰胺）、CH3CN-TEOA（CH3CN：乙腈）和 DMF-H2O 混合溶剂中，三种复合物表现出 PCO2R 活性，并具有较高的 CO 选择性（91%）。其中，DMF-TEOA 混合溶剂在光催化 CO2 还原成 CO 的过程中表现出最高的效率和 CO 选择性。Re（Hph）和 Re（dcbpy）在 DMF-H2O 中即使在低强度照射下也表现出光催化活性，这表明它们有望为人工光合材料的开发做出贡献。

Low-intensity-visible-light-driven photocatalytic CO2 reduction by rhenium tricarbonyl complexes based on pyridyl-triazole ligands

Photocatalytic CO₂ reduction (PCO2R) based on [Re(pyridyl-triazole)(CO)₃Cl] is demonstrated in various media, using triethanolamine (TEOA) and water as electron donors (EDs) under low-intensity visible-light irradiation. Three complexes exhibited PCO2R activity with high CO selectivity (> 91%) in DMF-TEOA (DMF: N, N’-dimethylformamide), CH₃CN-TEOA (CH₃CN: acetonitrile), and DMF-H₂O mixed solvents. Among these, the DMF-TEOA mixed solvents showed the highest efficiency and CO selectivity in photocatalytic CO₂ reduction to CO. Re(Hph) and Re(dcbpy) demonstrated photocatalytic activity even under low-intensity irradiation in DMF-H₂O, indicating their potential contribution to the development of artificial photosynthetic materials.

期刊介绍： The Journal of Organometallic Chemistry targets original papers dealing with theoretical aspects, structural chemistry, synthesis, physical and chemical properties (including reaction mechanisms), and practical applications of organometallic compounds. Organometallic compounds are defined as compounds that contain metal - carbon bonds. The term metal includes all alkali and alkaline earth metals, all transition metals and the lanthanides and actinides in the Periodic Table. Metalloids including the elements in Group 13 and the heavier members of the Groups 14 - 16 are also included. The term chemistry includes syntheses, characterizations and reaction chemistry of all such compounds. Research reports based on use of organometallic complexes in bioorganometallic chemistry, medicine, material sciences, homogeneous catalysis and energy conversion are also welcome. The scope of the journal has been enlarged to encompass important research on organometallic complexes in bioorganometallic chemistry and material sciences, and of heavier main group elements in organometallic chemistry. The journal also publishes review articles, short communications and notes.
