Abstract

Graphite powder‐supported cupric hexacyanoferrate (CuHCF) nanoparticles were dispersed into methyltrimethoxysilane‐based gels to produce a conducting carbon ceramic composite, which was used as electrode material to fabricate surface‐renewable CuHCF‐modified electrodes. Electrochemical behavior of the CuHCF‐modified carbon ceramic composite electrodes was characterized using cyclic and square‐wave voltammetry. Cyclic voltammograms at various scan rates indicated that peak currents were surface‐confined at low scan rates. In the presence of glutathione, a dear electrocatalytic response was observed at the CuHCF‐modified composite electrodes. In addition, the electrodes exhibited a distinct advantage of reproducible surface‐renewal by simple mechanical polishing on emery paper, as well as ease of preparation, and good chemical and mechanical stability in a flowing stream.

Chemically-modified carbon-wax composite electrodes were fabricated by incorporating appropriate quantities of model modifiers into melted wax/graphite-powder mixtures prior to the solidification step. Such melting and solidification processes result in homogeneous dispersion of the modifier and mec
