DOPED ELECTRODE AND USES THEREOF

摘要

The present invention relates to the electrochemical behaviour of carbon involving the use of a half cell set-up and solid sacrificial anode. The electrochemical oxidation of a selectively-contaminated graphite electrode has been assessed; the contaminants included anatase, alumina, pyrite, quartz, kaolin and montmorillonite. From the systematic introduction of these contaminants it was discovered that clay materials, such as kaolin and montmorillonite act catalytically to increase the rate of graphite oxidation. This demonstrates a clear effect of the solid phase interaction of contaminants upon the electrochemical oxidation of graphite; the same effect was not observed when the contaminants were added instead to the molten carbonate electrolyte.
