本文报道了多壁碳纳米管(MWNTs)对普鲁士蓝(PB)的电化学性能的显著改善。在多壁碳纳米管修饰的热解石墨(PG)电极上高效沉积了铅。用扫描电子显微镜和循环伏安法分别研究了PG/MWNTs/PB电极的微观结构和电化学行为。与PG/PB电极相比，PG/MWNTs/PB电极表现出更好的电化学稳定性，更宽的pH适应范围和更大的过氧化氢(H_2O_2)还原响应电流。研究了中性溶液pH下PG/MWNTs/PB电极对H_2O_2的安培响应。(C)2007 Elsevier B.V.保留所有权利。
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.
