Cu nanoparticles immobilized on modified magnetic zeolite as a new efficient catalyst for the synthesis of 1,2,3-triazoles via click chemistry reaction

Magnetically recoverable copper nanoparticle loaded on functionalized natural zeolite (CuNPs/MZN) as an efficient catalyst was synthesized. The Fe3O4 magnetic nanoparticles (MNPs) were immobilized into the pores of natural clinoptilolite zeolite which were modified with linkers having amino and hydroxyl groups and then CuNPswere decorated on the surface of functionalized zeolite. The CuNPs/MZN were characterized by FT-IR, CHN, TGA, ICP, XRD, SEM,TEM and BET techniques, successfully.The activity of the prepared catalyst was tested for the synthesis of 1,2,3- triazoles via click chemistry reactions which lead to the desired products in high yields and short reaction time. The eco-friendly, low cost and efficient CuNPs/MZN were separated from the reaction mixture via a simple external magnetic field, and reused several times, successfully
