Abstract
Polypyrrole/Fe2O3 (PPy/Fe2O3) nano-seeds with distinctive electrochemical properties have been successfully synthesized using improved hydrothermal processes. The study highlights the nano-seed like morphology of polypyrrole/Fe2O3 achieved by lowering both the reaction temperature and time (150 ℃ for 4 h), which are appreciable for energy storage applications. The obtained PPy/Fe2O3, analyzed using different techniques like X-ray photoelectron spectroscopy (XPS), Field Emission Scanning Electron Microscopy (FESEM), Fourier Transform Infrared (FTIR) spectroscopy. Compositional and morphological studies confirmed the formation of interconnected PPy/Fe2O3 nano-seeds. Cyclic Voltammetry response displays superior electrochemical performance of the PPy/Fe2O3. The interconnected nanostructures with voids allow more electrolyte ions to contact the active material, which significantly increases conductivity and electrochemical performance. As compared to the reported hydrothermal methods, the optimized routes take 4 h to achieve a specific nano-seed like morphology which is favorable for energy storage application.
