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 Fe 3 O 4 @SiO 2 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.
This study reports the synthesis and characterization of an environmentally friendly, cost‐effective, and sustainable Pd‐heterogeneous catalyst anchored on superparamagnetic silica‐coated iron oxide. The synthesized Pd‐SB/MNP nanomagnetic catalyst was extensively characterized using Fourier transform infrared (FTIR), inductively coupled plasma optical emission spectroscopy (ICP‐OES), X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), energy‐dispersive spectrometry (EDS), vibrating sample magnetometry (VSM), field emission scanning electron microscopy (FE‐SEM), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET), and high‐resolution transmission electron microscopy (HR‐TEM). The Pd‐SB/MNP catalyst showed remarkable efficiency in catalyzing the reduction of nitroarene and Cr(VI) under mild reaction conditions using an eco‐friendly solvent. The catalyst exhibits facile recovery through external magnetization, enabling its efficient recycling and reutilization for at least 10 cycles while demonstrating minimal Pd loss, as confirmed by rigorous hot filtration testing and ICP‐OES analysis. These results comply with the industry's prescribed thresholds for permissible levels of residual metallic content. The results suggest that the synthesized Pd‐SB/MNP catalyst holds great potential for various industrial applications.
