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

Abstract EN

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 55–60 nm and XRD confirmed its crystalline nature.

It showed photocatalytic decomposition of MB (>72%, k = 0.002164 min1, 10 mg/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.
