| dc.description.abstract | In the present work, a novel nanocatalyst system (Pd@CS–ZnO) was developed by adorning palladium nanoparticles on the hybrid nanocomposite consisting of chitosan and ZnO nanoparticles which are designed as a suitable stabilizer. Morphological/structural features of Pd@CS–ZnO were investigated by FT-IR, TEM, SEM, XRD, BET and EDS analyses. The catalytic efficiency of Pd@CS–ZnO was then assessed as a heterogeneous nanocatalyst against Heck coupling reaction. The tests revealed that Pd@CS–ZnO was a useful nanocatalyst which can couple the reactions of various aryl halides (I, Br, Cl) with styrene. Pd@CS–ZnO nanocatalyst proved to be easily separated with filtration and reapplied for six consecutive reaction runs. Additionally, it was found that the chemical structure of Pd@CS–ZnO was maintained during recycling tests, showing that it has high chemical stability. Furthermore, the designed catalyst system offers other benefits such as (1) cost efficiency, (2) eco-friendly nature, (3) facile preparation, (4) moisture/air insensitivity, (5) easy work up, and (6) high yields. | |
