Ultrasound agitated phytofabrication of palladium nanoparticles using Andean blackberry leaf and its photocatalytic activity

Abstract:

In this report, ultrasonication and Andean blackberry leaf extract are employed for the fabrication of palladium nanoparticles (PdNPs); and further evaluated its photocatalytic activity against methylene blue (MB). The as-synthesized PdNPs were characterized using UV-visible spectroscopy, transmission electron microscopy (TEM), Dynamic light scattering (DLS) and X-ray diffraction (XRD). TEM analysis demonstrated the formation of decahedron shape PdNPs with a diameter of 55-60nm and XRD confirmed its crystalline nature. It showed photocatalytic decomposition of MB (>72%, k=0.002164min-1, 10mg/L) in an aqueous solution under solar light irradiation. From the results obtained it is suggested that ultrasound agitated aqueous leaf extract demonstrates a simple, rapid, inexpensive method and should be utilized in future as green technology for the fabrication of nanoparticles.
