| Abstract: | Silver-graphene nanocomposites were fabricated at room-temperature based on graphene oxide and AgNO3 via a facile chemical reaction.The structure characterizations of Ag-graphene nanocomposites were studied by using XPS,XRD,TEM,and Raman,respectively.The number of oxygen functional groups on Ag-graphene sheets decreases dramatically,which implies that graphene oxide has been reduced to graphene.Ag nanoparticles adhering to the surface of graphene have an average grain size of about 25 nm.The Ag-graphene nanocomposites prepared in this study present a strong Surface Enhanced Raman Scattering effect,which have potential applications in sensors,nonlinear optics and electrocatalysis. |
