facile and efficient route for the synthesis of highly reduced graphene oxide (PE-HRG) by the green
reduction of graphene oxide (GRO) using the Pulicaria glutinosa plant extract (PE). The phytomolecules
present in the P. glutinosa extract are not only responsible for the reduction of GRO, but also for the
functionalization of the surface of the PE-HRG nanosheets and stabilize them in various solvents,
thereby limiting the use of any other external and harmful chemical reductants and surfactants. The
effect of PE on the dispersibility of PE-HRG in various solvents was investigated by preparing PE-HRG
with different amounts of PE, and the dispersibility of PE-HRG was compared with that of chemically
reduced graphene oxide (CRG). The reduction of GRO was confirmed by ultraviolet-visible (UV-vis),
Fourier-transform infrared (FT-IR), Raman and X-ray photoelectron (XPS) spectroscopies,
thermogravimetric analysis (TGA), X-ray powder diffraction (XRD) and transmission electron microscopy
(TEM).
