摘　　要：在常压条件下通过溶胶-凝胶法和碳化、活化工艺制备碳气凝胶材料。用SEM和BET比表面积测量等手段对材料的表面形貌和微观结构进行分析表征,通过循环伏安法对材料的电化学性能进行研究。联系材料的微观结构和电化学性能,对碳气凝胶的电除盐过程和除盐机理进行了研究和分析,发现碳气凝胶是一种具有很大应用潜力的多孔电极吸附材料。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.
