Preparation of Co3O4/graphene oxide composites by a depositing-decompostion method and its application for electrochemical determination of glucose
Co3O4/graphene oxide (GO) nanocomposites were successfully prepared by a depositing-decomposition method.The as-prepared samples were characterized by scanning electron microscopy (SEM) and Raman spectroscopy.Cyclic voltammetry (CV) was used to evaluate the electrochemical response of a glass carbon electrode (GCE) modified with Co3O4/GO nanocomposite towards glucose.Compared with the Co3O4/GCE,the Co3O4/GO/GCE exihibits higher electrocatalytic activity due to the synergistic effects of electrocatalytic ability of Co3O4 and large surface of GO.The Co3O4/GO/GCE was applied for glucose detection in alkaline solution.The linear current response range of glucose on Co3O4/GO/GCE covered the range from 9 × 10-5 to 6.03 ×10-3 M,with a detection limit of 5.2 × 10-7 M (S/N = 3).
