Abstract

Transition metal-based Metal–Organic Frameworks (MOFs) (M-BDC (M – Ni, Cu, Zn)) are prepared by solvothermal method. The loading of MOF on the support material, rGO, is done through the simple ultrasonication technique. The MOF materials are characterized using powder X-ray diffraction, Fourier-transform infrared spectroscopy, Scanning electron microscopy, and Thermogravimetric analysis. The catalytic activity of the synthesized MOFs is tested towards the dehalogenation of aryl halides reaction. The reaction conditions are optimized, in which the Ni-BDC MOF shows high catalytic activity. Hence, Ni-BDC MOF is loaded with different weight percentages (10wt%, 20wt%, 30wt%, and 40wt%) of rGO. Subsequently, 10 wt% Ni-BDC MOF/rGO is found to be the best catalyst among the other weight percentages of rGO-loaded catalysts. Moreover, the catalyst is easily recoverable and can be used for many cycles without leaching of active species, structural changes, and loss in activity.

使用可重复使用的还原氧化石墨烯负载简单过渡金属-有机框架在温和条件下催化芳基卤化物的高效脱卤

采用溶剂热法制备了过渡金属基金属有机骨架（M- bdc (M- Ni, Cu, Zn)）。MOF对支撑材料rGO的加载是通过简单的超声技术完成的。利用粉末x射线衍射、傅里叶变换红外光谱、扫描电镜和热重分析对MOF材料进行了表征。测试了所合成的MOFs对芳基卤化物脱卤反应的催化活性。对反应条件进行了优化，得到的Ni-BDC MOF具有较高的催化活性。因此，Ni-BDC MOF装载了不同重量百分比（10wt%、20wt%、30wt%和40wt%）的氧化石墨烯。结果表明，10 wt% Ni-BDC MOF/rGO是其他重量百分比rGO负载催化剂中最好的催化剂。此外，该催化剂易于回收，可以多次循环使用，而不会导致活性物质的浸出、结构变化和活性损失。图形抽象

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
