Fe3O4@APTES-TA-MA was characterized via FT-IR, EDS, SEM, TEM, VSM, and TGA methods. The average size of the nanoparticles was found between 40−90 nm. Clean procedure, short reaction time, and high efficiency are some benefits of this protocol. Also, the nanomagnetic catalyst can be reused five times without significant loss of its activity.}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, year={2024}, month={Mar.}, keywords={Magnetic catalyst, Covalent Organic Frameworks, One-pot reaction., Cyanoacetohydrazide, N-Amino-2-pyridone} }
