A simple, green method is described for the synthesis of Silver
(Ag) nanoparticles (NPs) from the peel extract of Pistachio. The
synthesized particles were characterized using UV-Vis, FT-IR
spectroscopy, XRD, EDAX, FESEM, and TEM images. The effect of
pH of the reaction, time, temperature, and amount of Pistachio
peel on the synthesis of AgNPs was evaluated. Unlike other
biological methods for NPs synthesis, the uniqueness of our
method lies in its appropriate synthesis rates and the ability to
tune the nanoparticle size via the used extract in the experi-
ment. AgNPs were used as a heterogeneous photocatalyst for
the degradation of eosin Y under visible light. Also, the
reduction of 4-nitrophenol to 4-aminophenol by AgNPs was
investigated and after 15 min this reaction was completed.
These results demonstrate a very efficient, cost-effective, and
benign method in the field of synthesis of nanoparticles and
catalysis technology development.
