Abstract

In this paper, we reported the preparation of carrageenan/reduced graphene oxide/Ag composite (CA-RGO-Ag) by a wet chemical method at room temperature using carrageenan, graphene oxide and silver nitrate as starting materials. As-prepared composite was characterized by UV-vis spectroscopy, Raman spectroscopy, FTIR, SEM, EDX and XRD. Results showed that the reduction of graphene oxide (GO) and silver nitrate was achieved simultaneously by addition of NaBH₄. Surface-enhanced Raman scattering study showed that the obtained composite give an intensive and enhanced Raman scattering when Rhodamine B was used as a probing molecule.
