摘要：

We report a simple method for the preparation of a hydrogen peroxide (H2O2) sensor based on reduced graphene oxide (rGO). ZnFe2O4 and Pt nanoparticles were supported on graphene sheets (Pt/ZnFe2O4/ rGO) to modify the glassy carbon electrode, which were used to detect H2O2. The morphology and structure of Pt/ZnFe2O4/rGO were characterized by scanning electron microscopy, transmission electron microscopy, X-ray powder diffraction and X-ray photoelectron spectroscopy. The property of the H2O2 sensor was evaluated by cyclic voltammetry and amperometry. The prepared H2O2 sensor showed a wide linear range from 0.5 mu m to 10.2 mM with a low detection limit of 0.1 mu M. (C) 2017 Elsevier B.V. All rights reserved.
