چکیده مقاله

This paper details the creation of BiFe2O4@SiO2@APTMS@Fmph-Ni, a novel magnetic nanocatalyst, synthesized under mild, environmentally conscious conditions. The catalyst's structure was rigorously characterized by physicochemical techniques, including X-ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS), Scanning Electron Microscopy (SEM), Fourier-Transform Infrared Spectroscopy (FT-IR), X-ray elemental mapping, Thermogravimetric Analysis (TGA), and Vibrating Sample Magnetometry (VSM). Polyhydroquinoline (PHQ) derivatives are important compounds because they have emerged as one of the most important classes of drugs for the treatment of cardiovascular diseases. The catalyst demonstrated excellent performance in Polyhydroquinolines reactions, achieving yields of up to 98% for (50 min reaction time) under optimized conditions. The heterogeneous nature of the catalyst was confirmed through hot filtration experiments. Furthermore, BiFe2O4@SiO2@APTMS@Fmph-Ni exhibited notable efficiency and reusability, maintaining its catalytic performance over at least five consecutive reaction cycles [1].
