Preparation of nanocomposite material based on Porphyrin and electrochemical analysis for green fuel production

Abstract

In the current environmental pollution situation, using green fuel sources such as H₂ gas to overcome the challenge of pollution and resource depletion is a useful solution. This research used the acid-base neutralization method with the recombination process to successfully fabricate CuFe₂O₄/TCPP nanocomposites. The morphological and structural properties of the materials were evaluated by scanning electron microscopy (SEM), X-ray diffraction (XRD) which show that the resulting material has a structure consisting of TCPP filaments with a diameter of about 20-30 nm and a length of µm, interspersed with CuFe₂O₄ particles with sizes in the range of 100 nm. The electrochemical properties of the as-prepared material film were investigated by Cyclic Voltammetry (CV) and electrochemical impedance spectroscopy (EIS) on a glassy carbon electrode with a 3-electrodes system. The results show the appearance of electrochemical characteristics of copper ferrite/porphyrin hybrid materials and especially the change of electrochemical characteristics when this nanocomposite was irradiated by an external light source. These results are expecting to apply this material in the photocatalytic process to produce green fuel H₂ from water.
