Abstract :
Synthesis of metal nanoparticles from the metal salts by reduction with plant extracts in water, without any additional stabilizing
or capping agents is a green and eco-friendly method. In the present work, aqueous extract of the bark of Terminalia
arjuna was utilized to synthesize T. arjuna-conjugated palladium nanoparticles (TA-PdNPs) from palladium chloride. The
dark brown colour indicating the formation of TA-PdNPs appeared within 3 h without heating but, on heating colour appeared
almost instantly. The synthesized TA-PdNPs are characterized by UV spectroscopy, HRTEM and XRD studies. The TAPdNPs
were utilized as efficient catalyst for Heck and Suzuki type C–C coupling reactions and degradation of organic dyes
in aqueous medium at room temperature.
