Abstract
The detection of hydrogen peroxide (H2O2) is considered important in various fields. This work described a resistive H2O2 sensor without using an enzyme, based on poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and N-doped graphene quantum dots (N-GQDs) composite on a transparent and flexible substrate. Using the drop-cast method, the uniform film was deposited onto interdigitated aluminum electrodes. The mechanism of H2O2 detection and reason for the use of GQDs have been explained. On exposure to 9 M H2O2, the sensing response obtained was 27.54%.
Keywords : H2O2, N-GQDs, PEDOT:PSS
