Polypyrrole single and double-shelled nanospheres templated by pyrrole-Hg(II) complex: Synthesis, characterization, formation mechanism and electrochemical performance

- We have synthesized polypyrrole (PPy) single and double-shelled hollow nanospheres.
- The synthesis of PPy nanostructures was templated by Py-Hg(II) complex.
- PPy hollow nanospheres used as supercapacitor material.
- We have investigated formation mechanism of PPy nanostructures.
