Abstract
- Abstract: A simple and environmentally friendly approach for the preparation of graphene nanosheets decorated with silver nanoparticles (Ag NPs) has been developed by gamma irradiation at room temperature. Graphene oxide (GO) and silver ions are simultaneously reduced by the electrons generated from the radiolysis of solvent. The addition of ionic liquid plays an important role in GO reduction by scavenging oxidative radicals generated during irradiation. Besides, the ionic liquid also benefits the dispersion and size distribution of Ag NPs. Raman signals of the obtained Ag-reduced graphene oxide are significantly enhanced, exhibiting obvious surface-enhanced Raman scattering activity. [Copyright &y& Elsevier]
