Au/ERGO nanoparticles supported on Cu-based metal-organic framework as a novel sensor for sensitive determination of nitrite

Abstract In this work, an electrode which comprises Au nanoparticles (AuNPs) and electrochemically reduced graphene oxide (ERGO) recombined Cu based metal-organic framework (Cu-TDPAT) was prepared for nitrite detection. The structure and constituent of the modified material were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and FT-IR. The electrochemical behavior of nitrite at the modified electrode was performed by cyclic voltammetry and electrochemical impedance spectroscopy. The results indicated that the oxidation process of nitrite happened at recommended electrode had a superior response. The proposed electrode showed high electrocatalytic capacity toward nitrite oxidation with a wide linear working range (0.001–1000 μmol·L−1) and a detection limit of 0.006 μmol·L−1. Finally, the sensor was successfully applied to detect nitrite in real sample and achieved desirable recovery rate, showing its potential application in real-time detection of food.
