- Аннотация: We propose to form nanoelectrode arrays by deposition of the electrocatalyst through lyotropic liquid crystalline templates onto inert electrode support. Whereas Prussian Blue is known to be a superior electrocatalyst in hydrogen peroxide reduction, carbon materials used as electrode support demonstrate only a minor activity. We report on the possibility for nanostructuring of Prussian Blue by its electrochemical deposition through lyotropic liquid crystalline templates, which is noticed from atomic force microscopy images of the resulting surfaces. The resulting Prussian Blue based nanoelectrode arrays in flow injection analysis mode demonstrate a sub-part-per-billion detection limit (1 x 10(-8) M) and a linear calibration range starting exactly from the detection limit and extending over 6 orders of magnitude of H2O2 concentrations (1 x 10(-8) to 1 x 10(-2) M), which are the most advantageous analytical performances in hydrogen peroxide electroanalysis.
