Carbon aerogel is a novel porous nanomaterial with extremely high specific surface area and electric conductivity. Carbon aerogel is synthesized under ambient pressure by sol-gel process and the following pyrolysis and activation process. This paper examins carbon aerogel by SEM, BET and eyelie voltammetry. The performance of carbon aerogel electrodes used in capacitive deionization uits is also investigated, which shows promising desalting results.
