  • Title: Acceleration effect of reduced graphene oxide on photoinduced synthesis of silver nanoparticles.
    Author: Tang B, Hou X, Li J, Zhang M, Sun L, Wang X.
    Journal: Phys Chem Chem Phys; 2013 Jul 14; 15(26):11106-12. PubMed ID: 23719756.
    Abstract:
    The photoinduced growth reaction of silver nanoparticles was accelerated by reduced graphene oxide (RGO) produced from graphene oxide (GO) during the light irradiation process in aqueous solution. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy demonstrated that RGO was generated in the photoinduced process. The acceleration effect of RGO was investigated through monitoring the extinction spectra of silver nanoparticles during the synthesis process. Moreover, transmission electron microscopy (TEM) was employed to characterize the evolution of morphologies of silver nanoparticles at different irradiation times to demonstrate the effect of RGO. The results indicate that RGO accelerates the photoinduced synthesis of silver nanoparticles. It is proposed that the acceleration effect of RGO on the photoinduced reaction is attributed to the particular property of high electronic conductivity.
