In this modern era, the human-technology is dependent on energy sources that are cheap, cost-effective, reliable, and energy-saving. The material was synthesized by using the Hummers method, coprecipitation method, and hydrothermal technique. X-ray diffractometry was utilized to calculate the confirmation of formation of material. By utilizing the UV-Vis. spectroscopy the transition between the pi - pi* transition explained the different effects on the properties of the material. In PL spectroscopy, the crystallinity of the material was analyzed, and the delocalized electrons move between Fe2+, Fe3+, CO, and Prussian blue nanoparticles. The capacitance and en-ergy dissipation were calculated through dielectric constants (real and imaginary). Grain boundaries possess a high resistivity at a lower frequency rate, a large amount of energy is needed to move the charge from one grain to another. An increment behavior is observed in the AC conductivity value against the applied frequency. The electrical properties were calculated with the help of impedance spectroscopy, and it also characterizes the in-terfaces of the conducting electrodes which are electronically and ionic conducted. With the help of four-probe method, it can be seen that as increasing voltages the value of current is also increasing and at 20 V the value of current 6 x 10-4 A is detected which shows the electrical conductivity behavior of the sample. The result of GO shows a small value of inhibition zone, but CO-PBGF shows a high value of inhibition zone which confirms the high antibacterial activity of CO-PBGF with respect to GO.
