Preparation of High Specific Surface Area Carbon Aerogels via CO2 Activation
二氧化碳活化法制备高比表面积碳气凝胶

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