Abstract
Carbon paste electrode (CPE) modified with metal–organic framework MIL-101 (MIL-CPE) was developed. The morphological characteristics of MIL-101 were characterized by scanning electron microscope (SEM) and N2 physical adsorption experiments. Electrochemical sensing features were studied by electrochemical impedance spectroscopy and cyclic voltammetry. The charge transfer resistance of [Fe(CN)6]3−/4− couple at the MIL-CPE was about 400 Ω which was considerably small than that of CPE. An enhanced electrocatalytic activity towards oxidation of dopamine (DA) and uric acid (UA) were observed with oxidative potentials of 218 mV for DA and 336 mV for UA at the MIL-CPE, respectively. Thus, the MIL-101 has great potential for applications in electrochemical sensors.
