Preparation of Core-Shell Magnetic Microspheres and Its Application in Jasminaldehyde Condensation Reactions

Metal nanoparticles (MNPs) have garnered significant attention due to their exceptional performance in heterogeneous reactions. Meanwhile, extensive applications have been found for metal-organic frameworks (MOFs), known for their ordered structure and high surface area. In this study, MNPs particles were amalgamated with MOFs to create a core-shell structure and were introduced amino groups into this configuration through post-synthetic modification (PSM), resulting in the successful synthesis of six distinct nanomaterials. Comprehensive characterization techniques, including infrared spectroscopy (IR), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS), confirmed the synthesis and modification of the MNPs/MOFs materials. These synthesized materials were employed as catalysts for the condensation reaction of jasminaldehyde. It is noteworthy that these catalysts exhibited outstanding performance, showcasing advantages over traditional heterogeneous catalysts. This superior performance is attributed in part to the advanced core-shell structure of these materials and the effective introduction of amino functional groups through the PSM technique.
