Facile synthesis of hierarchical conducting polypyrrole nanostructures via a reactive template of MnO₂ and their application in supercapacitors

We report an eco-friendly and one-step route for the chemical synthesis of hierarchical conducting polypyrrole (PPy) nanostructures via a reactive template of MnO₂. The as-prepared PPy nanotubes are found to show good electrical conductivity and superior electrochemical properties for supercapacitor applications.
