Electrochemical Detection of Hydrogen Peroxide at Carbon Nanotubes-Poly(Styrene-Co-N-Isopropylacrylamide) Nanoparticles Modified Electrode

Article Preview

Abstract:

Electrochemical sensors for the sensitive detection of H2O2 are for the first time described using carbon nanotubes/poly(styrene-co-N-isopropylacrylamide) nanoparticles (CNT/pS-co-NIPAm) modified glassy carbon electrode (GCE). The fabricated GCE is characterized using scan electron microscopy (SEM) and cyclic voltammetry (CV). The CNT/pS-co-NIPAm modified electrode has larger specific surface area and excellent electrocatalytic activity. The peak current of H2O2 obviously improves at modified GCE compared to bare electrode. The proposed electrode provides a promising avenue to develop novel electrochemical sensors.
