摘要

The development of nanoscience and nanotechnology has inspired scientists to continuously explorenew electrode materials for enhancing electrocatalytic activity and constructing electrochemicalplatform for sensing. In this study, we proposed a simple and effective approach to the in situdecoration of Cu2O nanoparticles on the surface of graphene nanosheets (Cu2O@CRG). The resultingmicrostructure and morphology were characterized by atomic force microscopy (AFM), transmissionelectron microscopy (TEM), energy-dispersive X-ray (EDX), X-ray powder diffraction (XRD)spectroscopy and electrochemical technique. The results confirm that the high dispersion of crystalCu2O nanoparticles with the uniform size distribution could be easily obtained via using sodium citrateas reductant and stabilizer. Moreover, the as-prepared Cu2O@CRG which modified glassy carbonelectrode (GCE) exhibit better non-enzymatic electrocatalytic responses to glucose than the chemicallyreduced graphene (CRG) or Cu2O in alkaline media. This new findings demonstrate Cu2O@CRG is apromising candidate of advanced electrode material in electrochemical sensing and otherelectrocatalytic applications.
