Abstract
AbstractIn this work, a new hydrogen peroxide (H2O2) sensor was reported based on electropolymerizing pyrocatechol violet (PCV) on a glassy carbon electrode modified with multiwalled carbon nanotubes (MWCNTs). The modified electrode was characterized by cyclic voltammetry (CV) and scanning electron micrography. The result of electrochemical experiments showed a favorable catalytic activity toward the reduction of H2O2 at −0.4 V with a linear response range from 2.0 μM to 2.4 mM and a detection limit of 0.7 μM (at a S/N = 3). The well catalytic activity of proposed sensor could be attributed to the poly‐PCV/MWCNTs composite film on the electrocatalytic reduction of H2O2. In addition, the sensor also exhibited a high sensitivity, good stability, and reproducibility. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
