This work presents a facile reactive template route to prepare polypyrrole (PPy) with a given, chosen nanostructure among three different morphologies (i. e. , nanotubes, nanofibers and urchins). This approach exploits the variability of MnO morphologies and its versatility as sacrificial template. [...]
