Abstract
Abstract In this study, a core–shell magnetic metal organic framework (MOF) catalyst was introduced based on Fe 3 O 4 magnetic nanoparticles (MNPs) and copper organic frameworks. In this catalyst, Fe 3 O 4 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.
