Electrochemical Studies on Different Glassy Carbon Electrodes II. Corrosion and Double Layer Characteristics

The consequences of heat treatment in production of glassy carbon has been investigated by scanning electron microspopy, ESCA and electrochemical methods. Correlation has been found between the temperature of treatment and the physical appearance and electrochemical reactivity. Glassy carbon appears to be a small band gap semiconductor with isolated well type surface states produced by residues of the surface oxidation processes
