Hydrogen peroxide sensor: Uniformly decorated silver nanoparticles on polypyrrole for wide detection range

- Electrochemical method was used for depositing silver nanoparticles and polypyrrole.
- Silver nanoparticles (25 nm) were uniformly decorated on electrodeposited polypyrrole.
- (Ag(NH3)2OH) precursor showed better electrochemical performance than (AgNO3).
- The sensor showed superior performance toward H2O2.
