Activation of Glassy Carbon Electrodes by Polishing with Ceramics Particles [PDF]

Bulletin of the Chemical Society of Japan, 1987
Abstract Glassy carbon electrode polished with ceramics particles (TiB2, SiC, and TiC) showed higher oxidation rate of ascorbic acid. The activation seems to depend on hardness of glassy carbon and ceramics particles and to be influenced by fresh edges formed on glassy carbon surface.
