This study explores the design and synthesis of magnetic UiO-66-NH2(Zr) functionalized with a Schiff base copper(II) complex via postsynthesis method, forming core-shell structure that acts as magnetically recyclable nanocatalyst. The nanocatalyst was synthesized using an affordable straightforward method abbreviated magnetic@UiO-66-NH-SB-Cu(II). For this purpose, magnetic@UiO-66-NH2 by modifying Fe3O4 tetraethyl orthosilicate, ZrCl4, 2-aminoterephthalic acid, stabilizing core, promoting Zr-MOF growth. surface pyrrole-2-carboxaldehyde CuCl2, followed characterization through various techniques.
