One pot hydrothermal synthesis amine-functionalized metal-organic framework/ reduced graphene oxide composites for electrochemical detection of bisphenol A

Abstract

In this paper, Amine-functionalized metal-organic framework/reduced graphene oxide (NH2-MIL-125/RGO) was prepared by one-pot hydrothermal reaction,then was coated on the surface of a glassy carbon electrode (GCE). Transmission electron microscope, Raman spectroscopy, X-ray diffraction, Fourier transform infrared and thermogravimetric analysis were carried out to characterize the NH2-MIL-125/RGO. In addition, the electrochemical detection of BPA in a phosphate solution was performed by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and AC impedance spectroscopy (EIS). Experimental results showed that NH2-MIL-125 was successfully hybridized with GO and NH2-MIL-125/RGO was well modified on GCE. The NH2-MIL-125/RGO/GCE displayed a high sensitivity and outstanding stability for detecting BPA, because of the advantage couple with large surface area of GO and high porosity of NH2-MIL-125. Under the optimum conditions, the current of oxidation peak of BPA was well linear with its concentration which from 2.00 to 200.00 μM, and limit of detection(S/N=3) was calculated to be 0.7966 μM. The result indicated that a favorable, high sensitivity and good conductive performance electrochemical sensor was successfully conduct for detection of BPA.
