Preparation, characterization, and catalytic application of Pd nanoparticles immobilized on silica

Palladium nanoparticles on modified silica have shown to act as an active, stable, and reusable heterogeneous catalyst for the Heck and Sonogashira reaction with high conversion. The catalyst containing Pd nanoparticles were characterized by FT-IR, UV-vis, CHNS, TEM and ICP. The products of the reaction were analyzed by GC-MAS. The catalyst has high reusability and it shows that the tailored ligand is an efficient coordinator for palladium
