Non-enzymatic electrochemical sensing of hydrogen peroxide based on polypyrrole/platinum nanocomposites

- The PPy/Pt nanocomposite was prepared by surfactant-free microwave-assisted polyol process.
- The PPy/Pt nanocomposite possessed a good electrocatalytic activity toward the reduction of H2O2.
- A nonenzyme electrochemical sensor of H2O2 based on PPy/Pt nanocomposite was constructed.
