Abstract

 

Green and eco-friendly synthesis of palladium nanoparticles NPs is carried out under

facile and eco-friendly conditions using an aqueous solution of

 

Salvadora persica L. (SP) root

extract (RE) as a bioreductant, which is commonly known as Miswak. The as-synthesized Pd

NPs were characterized using various spectroscopic and microscopic techniques, including, UV–

Vis spectroscopy, FT-IR spectroscopy, XRD, ICP-MS and TEM. Detailed investigations of the

Pd NPs have confirmed that the polyphenolic phytomolecules present in the RE of Miswak not only

act as a bioreductant by facilitating the reduction and growth of Pd NPs, but they also functionalize

the surface of Pd NPs and stabilized them in various solvents. Furthermore, the catalytic activity of

the green synthesized Pd NPs was also tested toward the Suzuki coupling reactions of various aryl

halides in aqueous media. The as-prepared Pd NPs exhibited superior catalytic activity and

reusability for the Suzuki coupling reaction in aqueous and aerobic conditions. The kinetics of

the reaction studied by GC revealed that the conversion of various aryl halides to biphenyl takes

place in a short time
