A novel electrochemical sensor based on Cu-MOF and reduced graphene oxide (RGO) was fabricated for the determination of metoclopramide (MP)[1-3]. The modification procedure was carried out through casting RGO on the bare glassy carbon electrode (GCE) and followed by the electrodeposition of Cu-MOF on the RGO modified electrode. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM) were performed to characterize the electrochemical performance and surface characteristics of the as-prepared sensor. The composite electrode exhibited an excellent electrocatalytic activity with increased electrochemical signals towards the oxidation of MP, owing to the synergistic effect of RGO and Cu-MOF. Under the optimized condition, the linear response range were from 0.1 to 154 μmol L-1 for MP. The detection limits for MP were 0.08 L-1. Moreover, the modified electrode presented the good reproducibility and the excellent anti-interference performance.
