A green, one-step approach for the preparation of graphene/Ag nanocomposites
(PE-HRG-Ag) via simultaneous reduction of both graphene oxide (GRO) and silver ions
using Pulicaria glutinosa plant extract (PE) as reducing agent is reported. The plant extract
functionalizes the surfaces of highly reduced graphene oxide (HRG) which helps in
conjugating the Ag NPs to HRG. Increasing amounts of Ag precursor enhanced the density
of Ag nanoparticles (NPs) on HRG. The preparation of PE-HRG-Ag nanocomposite is
monitored by using ultraviolet–visible (UV-Vis) spectroscopy, powder X-ray diffraction
(XRD), and energy dispersive X-ray (EDX). The as-prepared PE-HRG-Ag nanocomposities
display excellent surface-enhanced Raman scattering (SERS) activity, and significantly
increased the intensities of the Raman signal of graphene.
