The catalyst identification was performed using Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). The magnetic analysis showed that the Ni0.5Cu0.5Fe2O4 had a ferromagnetic behavior with a saturation magnetization of 31.22 emu/g at room temperature. Then, Ni0.5Cu0.5Fe2O4 magnetic nanoparticles were applied as a green, convenient, effective and reusable catalyst for the one-pot three-component synthesis of tetrahydrobenzo[b]pyrans in good to excellent yields. It should be noted, the nanocatalyst is separated by a magnet was used several times and it was as efficient as ever.}, number={3}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Ahankar, Hamideh and Fardood, Saeid Taghavi and Ramazani, Ali}, year={2024}, month={Feb.}, keywords={Ferrite, Tetrahydrobrnzo[b]pyran drivetives, Microwave irradiation, Solvent-free, Magnetic nanoparticles} }
