Abstract
- A novel Prussian blue/copper-gold bimetallic nanoparticles hybrid film modified electrode was prepared by electrochemical deposition on a glassy carbon electrode (PB/Cu-AuNPs/GCE). Morphology and electrochemistry of this electrode were studied by UV-vis spectroscopy, scanning electron microscopy, X-ray diffraction, cyclic voltammetry and electrochemical impedance spectroscopy. The sensor showed significantly better electrocatalytic activity for the reduction of hydrogen peroxide in comparison with the single PB/GCE and PB/AuNPs/GCE. This was attributed to the synergistic effect of PB and Cu-Au bimetallic nanoparticles. Also, the sensor demonstrated an overall high level of performance for the analysis of H2O2 in the concentration range from 0.002 to 0.84 mM. [ABSTRACT FROM AUTHOR]
