Abstract
A novel nanocatalyst, denoted as UiO-66/Sal-ZnCl(2), has been synthesized and systematically characterized employing a range of analytical techniques, including Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), Brunauer-Emmett-Teller (BET) surface area analysis, and inductively coupled plasma (ICP) analysis. The comprehensive analyses collectively affirm the effective coordination of zinc chloride onto the functionalized UiO-66. Subsequently, the catalytic efficacy of UiO-66/Sal-ZnCl(2) was assessed in a one-pot, three-component click reaction involving terminal alkynes, alkyl halides, and sodium azide, conducted in an aqueous medium. The catalyst demonstrated remarkable catalytic activity, showcasing the capability to facilitate the reaction with high yields and exceptional regioselectivity. Noteworthy attributes of this nanocatalyst and the method include its elevated efficiency, recyclability, convenient product workup, and, significantly, the utilization of a sustainable solvent medium. The synthesis, characterization, and catalytic performance of this catalyst collectively contribute to its potential as an innovative and reusable nanocatalyst for diverse synthetic transformations.
