摘要

In the present work, we reported a copper complex immobilized onto magnetic SBA-15 nanoparticles (Fe3O4/SBA-15) as a magnetic nanocatalyst. The designed catalyst was authenticated using the following techniques: FT-IR, XRD, BET, TEM, TGA, EDS, VSM, and ICP-OES. Then, its catalytic performance was studied in the Suzuki cross-coupling reaction. The influences of different factors like solvent type, reaction time, reaction temperature, base type, and catalyst amount on the reaction efficiency were examined in detail. The aforesaid magnetic catalyst was effectively catalyzed the Suzuki cross-coupling reaction of arylboronic acids and various aryl halides at room temperature in water as cheap and green media. Furthermore, the catalyst maintained consistent activity over six cycles without any significant decline in performance. Besides, its magnetic feature made it easy to recover and reuse. Interestingly, the developed catalyst exhibited better performance than most of the heterogeneous Cu-based catalysts reported previously.
