Abstract

The present study describes an eco-friendly approach for the synthesis of colloidal solution of silver and gold nanoparticles

(L-AgNPs and L-AuNPs) from the aqueous extract of Lactuca indica leaf. Major parameters afecting on the formation

of L-AgNPs and L-AuNPs were optimized using UV–Vis analysis at absorption maximum around 423 nm and 531 nm,

respectively. The plant extract as reducing and capping agents of MNPs was demonstrated by Fourier-transform infrared

(FTIR) spectroscopy. The nanoscale of metals was confrmed by Transmission electron microscopy (TEM) measurements.

TEM studies revealed that L-AgNPs were mostly spherical with average size of 13.5 nm and L-AuNPs possessed multi

shapes with an average size of 14.5 nm. Selected area electron difraction (SAED) analysis and X-ray difractometer (XRD)

data confrm their crystalline structure. The nanomaterials showed efcient catalysis in the degradation of 4-nitrophenol

and methyl orange.
