Abstract
Here a simple strategy was employed to fabricate a hydrogen peroxide (H 2 O 2 ) sensor based on gold nanoparticles and palladium nanoparticles onto a tungsten wire. The electrochemical activities of the bimetallic nanoparticles decorated electrode were characterized by the voltammetry and amperometry. The decorated electrode showed excellent catalytic activity towards the H2O2 reduction. The fabricated electrode demonstrated a good linear range, fast response time, good reproducibility, and a sensitivity of 0.317 mA mM-1 cm-2 for H 2 O 2 detection. In addition, it also showed good antiinterference capability towards common interfering analytes. Thereby, the fabricated sensor has the potential to be used as a simple, rapid, and cost-effective non-enzymatic sensor.
