Reduced graphene oxide/CdCO3 (RGO/CdCO3) nanocomposites were prepared by a one-pot solvent-assisted thermal reduction method under mild conditions. The as-prepared nanocomposites were characterized by Xray diffraction (XRD), transmission electron microscopy (TEM), Raman and Fourier transform infrared spectroscopy (FT-IR), and the results indicate that the CdCO3 nanoparticles were successfully formed on the RGO sheets during the one-step process. Furthermore, the electrochemiluminescence (ECL) properties of the RGO/CdCO3 nanocomposites were investigated in aqueous systems, which show that the presence of RGO/CdCO3 film can not only enhance the ECL intensity of peroxydisulfate but can also decrease its onset potential. This novel strategy has been extended to synthesize RGO/metal carbonate nanocomposites for potential applications in ECL analysis. (C) 2012 Elsevier B.V. All rights reserved.
