Abstract

The surfaces of electrochemically modified graphite electrodes have been studied using ESCA, scanning Auger microscopy, and chemical titration. Quantitative evaluation of surface functionalities after electro-oxidation in sulfuric acid provides an understanding of their mechanistic role in synthetic uses of the carbon electrode. Specifically concentrations of acid and phenolic groups are correlated with the level of oxidation on the electrode. A plateau is reached at between 4 and 22 C/cm².
