摘要

本研究探讨了在叶酸功能化石墨烯纳米复合材料（CuO-FAFGNCs）中嵌入氧化铜纳米颗粒对亚甲基蓝（MB）的催化降解。采用叶酸对石墨烯进行功能化，然后包埋氧化铜纳米颗粒，制备了纳米复合材料。通过UV-Vis， FT-IR， XRD， TEM和SEM表征证实了材料的成功合成和结构完整性。使用NaBH₄作为还原剂评估催化活性，在16分钟内达到近90%的MB降解，遵循伪一级动力学（k = 0.1477 min⁻¹）。虽然纳米复合材料在污水处理方面显示出强大的潜力，但由于表面污染或结构变化，重复使用可能会导致性能下降。需要进一步的研究来评估对其他污染物的有效性。

Enhanced methylene blue degradation of copper oxide nanoparticles embedded functionalized graphene nano composites

This study explores the catalytic degradation of methylene blue (MB) using copper oxide nanoparticles embedded in folic acid-functionalized graphene nanocomposites (CuO-FAFGNCs). The nanocomposites were synthesized by functionalizing graphene with folic acid followed by embedding CuO nanoparticles. Characterization through UV-Vis, FT-IR, XRD, TEM, and SEM confirmed the successful synthesis and structural integrity of the material. Catalytic activity was assessed using NaBH₄ as a reducing agent, achieving nearly 90 % MB degradation within 16 minutes, following pseudo-first-order kinetics (k = 0.1477 min⁻¹). While the nanocomposites show strong potential for wastewater treatment, performance may decline over repeated use due to surface fouling or structural changes. Further studies are needed to assess effectiveness against other contaminants.

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.
