The glassy carbon electrode (GCE) modified with mesoporous NiCo2O4-decorated reduced graphene oxide (NiCo2O4/rGO) was first applied for the electrochemical determination of rutin. The synthesized NiCo2O4 and NiCo2O4/rGO were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Brunauer-Emmett-Teller (BET) method. The sensor not only showed a satisfactory linear range (0.1-150μM) and detection limit (0.01μM) but also exhibited the good anti-interference abilities, low price, high stability, as well as favorable precision and accuracy. The present work is meaningful to expand functionalized graphene composites to sensor fields and promote the development of rutin sensors.
