Özet
In this study, a heterogeneous nano-system with sustainable, green, highly effective, and easily recoverable properties was developed through deposition of palladium nanoparticles on chitosan-MgAl layered double hydroxide hydrogel beads (CS-MgAl LDH). Full characterization of the system denoted as Pd-CS-MgAl LDH nanocatalyst was performed by various analytical techniques including FT-IR, FE-SEM, EDS, TEM, and XRD analyses. The catalytic activity of Pd-CS-MgAl LDH was then explored in Heck cross coupling reaction, and the tests confirmed that Pd-CS-MgAl LDH is an effective and useful nanocatalyst which can couple different aryl halides with yields in the range of 90–98%. Additionally, it was found that Pd-CS-MgAl LDH nanocatalyst displays higher catalytic performance compared to other reported catalysts. Moreover, Pd-CS-MgAl LDH nanocatalyst was facilely isolated and recycled for 5 successive runs without a discernible change in its performance, showing that Pd-CS-MgAl LDH has good recoverability and practical application potential.
