This study presents a novel catalytic system combining magnetic nanocellulose (MNC) and NH2-UiO-66 microcrystals, modified with salicylaldehyde (Sal) and copper ions. The goal is to exploit the synergistic effects of nanocellulose and metal-organic frameworks (MOFs) to develop a catalyst with superior performance compared to conventional systems. This innovative approach provides significant improvements over previous catalysts by enhancing reaction efficiency, reducing reaction time, improving environmental sustainability, offering high stability, and enabling the easy separation of the nanocatalyst from the reaction medium. Magnetic nanoparticles (MNPs) are synthesized for efficient separation, and coated with a nanocellulose matrix to increase hydrophilicity, enhance dispersion in aqueous solutions, reduce toxicity, improve biocompatibility, and facilitate the mass transfer process. The incorporation of NH2-UiO-66 microcrystals on the MNC surface further enhances the catalytic efficiency. The modification of NH2-UiO-66 with Sal ensures optimal copper ion distribution, thereby enhancing catalytic activity. The catalyst was evaluated in the synthesis of triazole derivatives, showing remarkable stability with nearly constant reaction efficiency over four cycles. However, challenges persist in optimizing long-term stability, and further exploration is required to minimize degradation. This work represents a significant advancement in catalytic systems for triazole synthesis, with promising applications in green chemistry.
