A novel nonenzymatic hydrogen peroxide sensor based on silver nanoparticles and ionic liquid functionalized multiwalled carbon nanotube composite modified electrode

- A novel nonenzymatic H2O2 sensor was constructed on AgNPs/MWCNTs-IL modified GCE.
- Ionic liquid functionalized carbon nanotube was used as matrices for deposition of AgNPs effectively.
- AgNPs were uniformly and less agglomerate formed on the MWCNTs-IL film.
- AgNPs/MWCNTs-IL/GCE displayed good electrocatalytic activity to the reduction of H2O2 and applied to real samples.
- The electrocatalytic mechanism of the constructed sensor was proposed.
