Abstract: Carbon aerogels were synthesized from sol-gel polymerization of resorcinol-formaldehyde and dried under ambient pressure and room temperature. The specific surface area of carbon aerogels after the CO2 activation would be three times larger than that of normal ones. The microstructures of carbon aerogels were investigated by scanning electron microscope (SEM) and specific surface area measurement, and the process parameters were optimized.

Key words: carbon aerogles, ambient drying process, activatio
