A novel non-enzymatic H2O2 sensor based on polypyrrole nanofibers-silver nanoparticles decorated reduced graphene oxide nano composites

- Decorating silver nanoparticles on the surface of graphene oxide nanocomposites.
- Using and comparing two different electrochemical methods for reducing graphene oxide.
- Investigating the effect of cyclic voltammetry and amperometry on electropolymerization of polypyrrole nanofibers.
- The senor shows superior performances (LOD, LOQ, selectivity, repeatability, reproducibility and stability) towards H2O2.
