Abstract
Polydopamine functionalized reduced graphene oxide-silver nanoparticle (PDA-RGO/Ag NP) nanocomposites were successfully prepared by a simple and mild procedure. Graphene oxide (GO) sheets were firstly coated with PDA via a self-polymerization process which provided an excellent interface for in-situ growing silver nanoparticles. Fourier transform infrared spectroscopy (FTIR) confirmed the successful coating of PDA and informed the reduction of the surface functional groups of GO. The formation of reduced GO and silver NPs was further evidenced by UV-Vis and X-ray diffraction spectroscopy. The as-prepared PDA-RGO/Ag nanocomposites could greatly enhance the electrochemical reduction of hydrogen peroxide (H2O2). This excellent performance was attributed to the increased effective electrode surface area due to the deposition of nano-sized Ag particles and graphene. The PDA-RGO/Ag-based electrochemical sensor displayed a rapid amperometric response for H2O2 measurement with a wide linear range from 0.5 μM to 8 mM and a low detection limit of 2.07 μM.
