3D nitrogen-doped graphene aerogel: A low-cost, facile prepared direct electrode for H2O2 sensing

- A novel 3D nitrogen (N) doped graphene aerogel (GA) was used as a direct electrode for electrochemical sensing.
- Owing to the 3D open-pore structure and nitrogen doping property, the sensor showed excellent electrocatalytic activity towards H2O2 reduction.
- The proposed non-enzymatic sensor was applied for H2O2 detection.
