Electrochemical sensors are currently being developed and widely applied in many fields with new materials to increase the accuracy and selectivity of the method. In this study, Fe/GNPs materials were synthesized from green chemistry method, combined with recombinant TCPP process to create Fe/GNPs/TCPP nanocomposite materials. The structure and morphology of the formed products were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy. The morphological and structural analysis results of the products showed that Fe/GNPs/TCPP nanocomposites were formed from nano-structured zero valent iron particles with an average size of 15-60 nm uniformly distributed on the surface of graphene plates 2-10 nm thick, interspersed with porphyrin nanofibers with a diameter of 30 nm. The materials were investigated and evaluated for their electrochemical properties through cyclic potential scanning (CV), electrochemical impedance spectroscopy (EIS) on a three-electrode electrochemical system. The electrochemical analysis results have demonstrated that Fe/GNPs/TCPP nanocomposite materials have good properties suit for application as electrochemical sensors in the analysis of residues of antibiotics, pesticides in agricultural production.
