In this work, we investigated the textural characteristics of carbon aerogel by varying the heat-treatment temperature. carbon aerogel was prepared by direct synthesis method. And then, the KOH/carbon aerogel composites were heat-treated to increase the specific surface area and microporosity. The structural properties were characterized by X-ray diffraction. The feature and morphologies were observed by scanning electron microscopy. The textural properties were analyzed by N2/77K adsorption. The CO2 adsorption behaviors were evaluated pressure swing analysis. From the results, it was found that the CO2 adsorption behaviors were strongly affected by the specific surface area of carbon aerogel. |
