摘要

Graphene with different amounts of defects was prepared by chemical vapor deposition by controlling the flow rate of hydrogen, on which Ag nanoparticles (NPs) were deposited by magnetron sputtering. It is certified that the defects mainly consist of C–O bonds that affect the morphology and distribution of the prepared Ag NPs. The Ag NPs/graphene composition exhibits good surface-enhanced Raman scattering activity, which is largely increased by increasing the percentage of the functional group C–O in graphene.
