Abstract
We have fabricated carbon/ceramic composite electrodes with an interco nnected network of carbon particles in a silica-based gel. The resulti ng electrodes were porous and electrically conductive and exhibited ex cellent stability. BET adsorption measurements combined with electroch emical techniques such as cyclic voltammetry and electrochemical imped ance spectroscopy showed that 50% of the carbon surface Nea was access ible electrochemically.
