英文摘要There is current interest in developing carbon nanomaterials, which are a novel kind of nanomaterial, for uses in electrochemical sensing and biosensors. We constructed a novel sensor based on a Pt nanoparticles-carbon quantum dots/ionic liquid functionalized graphene oxide (PtNPs-CDs/IL-GO) nanocomposite for detecting H2O2. We characterized the morphology and electrochemical performance of the modified electrode using scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and cyclic voltammetry, respectively. The unique chemical structure of PtNPs-CDs/IL-GO greatly accelerated the catalysis of H2O2 and provided plenty of active sites for electrochemical redox reactions. Electrochemical experiments demonstrated that the PtNPs-CDs/IL-GO sensor had high selectivity, a wide linear range from 1 to 900 mu M, and a low detection limit of 0.1 mu M with respect to the reduction of H2O2. These characteristics indicate good electrical conductivity and high electrocatalytic activity. This simple and effective method has potential applications in chemical sensors and electrochemical catalysis. (C) 2017 Elsevier B.V. All rights reserved.
