摘要：

This paper reports on the greatly improved electrochemical properties of prussian blue (PB) by multi-walled carbon nanotubes (MWNTs). PB was efficiently deposited on the MWNTs modified pyrolytic graphite (PG) electrode. The microstructure and electrochemical behavior of the PG/MWNTs/PB electrodes were investigated by scanning electron microscopy and cyclic voltammetry, respectively. Compared with the PG/PB electrode, the PG/MWNTs/PB electrode shows much better electrochemical stability, much wider pH adaptive range and larger response current to the reduction of hydrogen peroxide (H2O2). Amperometric response of the PG/MWNTs/PB electrode to H2O2 at neutral solution pH was also investigated. (c) 2007 Elsevier B.V. All rights reserved.
