Nanostructured Dy2Ce2O7 with good electrochemical hydrogen storage properties has been produced utilizing a novel and green method in the presence of fig extract, for the first time. Fig extract has been employed as novel kind of fuel in the production of pure Dy2Ce2O7. By varying the notable factor, temperature for production, Dy2Ce2O7 structures can be created that are different in morphological features and Coulombic efficiency as well as electrochemical hydrogen storage properties. Diverse techniques have been adopted to examine and characterize the formed Dy2Ce2O7 with the aid of fig extract. Electrochemical hydrogen storage features of the diverse Dy2Ce2O7 samples (formed with the aid of fig extract) have been compared with chronopotentiometry technique at potash solution. Our findings reveal that the nanostructured Dy2Ce2O7 fabricated with the aid of fig extract at 400 degrees C can possess the best efficiency for store hydrogen. Usage of fig extract, the new and eco-friendly fuel, for synthesis of the nanostructured Dy2Ce2O7 that is efficiently capable to store hydrogen (renewable type of energy carrier), can be helpful to decline and stop the environmental pollution.
