摘要：
Exfoliated graphite was covalently functionalized with 2,9,16,23-tetraamino cobalt(H) phthalocyanine and used as a surface renewable electrode material. The modified graphite was characterized using IR spectroscopy, X-ray photoelectron spectroscopy and cyclic voltammetry. Surface renewable, porous, ceramic-carbon electrodes were fabricated using sol-gel derived silicate as a binder and used for the electrocatalytic oxidation of hydrogen peroxide. The storage stability of the renewable surface composite electrode was found to be 18 months with an operational stability of over 5 h. (C) 2003 Elsevier B.V. All rights reserved.
