In this study, a core-shell magnetic metal organic framework (MOF) catalyst was introduced based on FeO magnetic nanoparticles (MNPs) and copper organic frameworks. In this catalyst, FeO MNPs have been coated with MOFs in which copper was the inorganic nodes and 1,3,5-benzenetricarboxylic acid was the organic linkers. Then, the core-shell structures and catalytic efficiency have been confirmed properly and completely with various analyses such as FT-IR, TEM, SEM, TEM mapping, SEM mapping, EDX, PXRD, TGA, ICP and VSM. The Cu moieties in MOF and shell structures can catalyze the synthesis of 1,2,3-triazole derivatives with good to excellent yields in the presence of water as a green solvent. Moreover, this catalyst showed the high reusability due to the super paramagnetic properties.

在本研究中，基于FeO磁性纳米颗粒（MNP）和铜有机框架引入了一种核壳磁性金属有机框架（MOF）催化剂。在这种催化剂中，FeO MNP被MOF包覆，其中铜为无机节点，1,3,5-苯三甲酸为有机连接体。然后，通过傅里叶变换红外光谱（FT-IR）、透射电子显微镜（TEM）、扫描电子显微镜（SEM）、TEM图谱、SEM图谱、能量散射X射线光谱（EDX）、粉末X射线衍射（PXRD）、热重分析（TGA）、电感耦合等离子体质谱（ICP）和振动样品磁强计（VSM）等各种分析方法，对核壳结构和催化效率进行了全面且恰当的确认。在水作为绿色溶剂存在的情况下，MOF和壳结构中的铜部分能够催化合成产率良好至优异的1,2,3-三唑衍生物。此外，由于具有超顺磁性，该催化剂表现出高可重复使用性。
