New materials based on nanostructured Prussian blue for development of hydrogen peroxide sensors

Analytical performances of the resulting PB based nanoelectrode arrays have been studied in course of hydrogen peroxide detection in FIA mode. The value of sensitivity for obtained sensors was 0.2 A M−1 cm−2, which is two times more than for electrodes modified by PB electrodeposited through liquid crystal template. Detection limit was 10−8 M and a linear calibration range was extending over six orders of magnitude of H2O2 concentrations, which are the most advantageous analytical performances in hydrogen peroxide electroanalysis nowadays.
