A new idea in energy harvesting is to employ hydroelectric cells (HECs) to produce cleaner energy from water dissociation. Hydroelectric cells are beneficial and eco-friendly inventions of this century, which dissociate water molecules to generate electricity without an electrolyte. In this study, a sol-gel method was used to synthesize Mg0.7Zn0.3Fe2O4 nanoferrite in order to construct a hydroelectric cell that produces electricity by the dissociation of water molecules. X-ray diffraction revealed the cubic crystal structure (Fd-3m space group) with a crystallite size of 30.79 nm, approximately. For water to split on the surface of ferrite, substantial water absorption at 1638 and 3438 cm-1 , and metal oxide bonds near 418 cm-1 and 547 cm-1 are shown by FTIR spectroscopy. FESEM imaging of the prepared ferrite with an average grain size of 91 nm exhibited porosity in the prepared ferrite, which is 40.2 % theoretically by XRD studies. The crystallographic defects and O2 (oxygen) vacancies required for water dissociation are shown in PL studies performed at room temperature. The impedance analysis demonstrated a semi-circular Nyquist plot and a small tail, which signifies the presence of a low charge transfer resistance and Warburg impedance, respectively. The described ferrite surface dissociates water into H3O + and OHions by an electrolytic chain reaction, creating a voltage across electrodes. The V-I polarization plot indicated the offload current, open circuit voltage and offload power of 7 mA, 0.823 V and 5.61 mW, respectively. The enhanced porosity, crystal defects and oxygen voids are responsible for the dissociation of water molecules for the generation of electricity in Mg0.7 Zn0.3 Fe2O4 fabricated hydroelectric cell.
