Description
Summary:This study depicts the novel synthesis of sustainable, cost‐effective, and environmentally friendly Schiff base‐Pd nanomagnetic heterogeneous catalyst (MNP‐AF‐Pd) decorated on superparamagnetic Fe3O4@SiO2 core‐shell magnetic nanoparticles. The synthesized MNP‐AF‐Pd catalyst were characterized by thermogravimetric analysis (TGA), Fourier transform infrared (FT‐IR), X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), inductively coupled plasma‐optical emission spectrometry (ICP‐OES) analysis, Brunauer–Emmett–Teller (BET), energy dispersive X‐ray analysis (EDX), vibrating‐sample magnetometer (VSM), field‐emission scanning electron microscopy (FE‐SEM), and high‐resolution transmission electron microscopy (HR‐TEM). The synthesized MNP‐AF‐Pd catalyst was shown to be an effective catalyst for Suzuki–Miyaura cross‐coupling reaction of several aryl boronic acid and degradation of hazardous organic dyes, particularly rhodamine B and methylene blue under mild reaction conditions. The catalyst is simply retrieved, recovered, and repeatedly utilized for several cycles without appreciably diminishing catalytic activity.
