英文摘要: A Prussian Blue (PB)/polyaniline (PANI)/multi-walled carbon nanotubes (MWNTs) composite film was fabricated by step-by-step electrode-position on glassy carbon electrode (GCE). The electrode prepared exhibits enhanced electrocatalytic behavior and good stability for detection of H2O2 at an applied potential of 0.0 V The effects of MWNTs thickness, electrodeposition time of PANI and rotating rate on the current response of the composite modified electrode toward H2O2 Were optimized to obtain the maximal sensitivity. A linear range from 8 x 10(-9) to 5 x 10(-6) M for H2O2 detection has been observed at the PB/PANI/MWNTs modified GCE with a correlation coefficient of 0.997. The detection limit is 5 x 10(-9) M on signal-to-noise ratio of 3. To the best of our knowledge, this is the lowest detection limit for H2O2 detection. The electrode also shows high sensitivity (526.43 mu A mu M-1 cm(-2)) for H2O2 detection which is more than three orders of magnitude higher than the reported. (c) 2006 Elsevier B.V.
