Prussian blue-based nano-electrode arrays

Prussian blue-based nano-electrode arrays were formed by deposition of the electrocatalyst through lyotropic liquid crystalline [144] or sol templates onto inert electrode supports. Alternatively, nucleation and growth of Prussian blue at early stages results in nano-structured film [145], Whereas Prussian blue is known to be a superior electrocatalyst in hydrogen peroxide reduction, carbon materials used as an electrode support demonstrate only a minor activity. Since the electrochemical reaction on the blank electrode is negligible, the nano-structured electrocatalyst can be considered as a nano-electrode array. 

The resulting Prussian blue-based nano-electrode arrays in FIA demonstrate a sub-ppb detection limit (1 X 10 9 mol I. ) and a linear calibration range starting from the detection limit and extending over seven orders of magnitude of H202 concentrations (1 X 10 9 1 X 10 2 mol L ), which is the most advantageous analytical performance in electroanalysis. As a conclusion from the evidence in this chapter, Prussian...
