    Abstract: A method for preparing carbon aerogels and carbon aerogels obtained therefrom are disclosed. The method for preparing carbon aerogels comprises: mixing organic starting materials including phloroglucinol and furfural with a solvent capable of dissolving the organic materials in a predetermined ratio to form a sol solution; adjusting pH of the sol solution adequately by using an acidic or basic catalyst, gelling the sol solution at room temperature under atmospheric pressure, and aging the resultant gels; substituting the solvent in thus obtained gels with liquid carbon dioxide, followed by drying in a supercritical state, to form organic aerogels; and pyrolyzing the organic aerogels in an electric furnace under inert atmosphere to obtain carbon aerogels. Particularly, the gels are formed at room temperature in a short period of time by adequately adjusting pH of the sol solution. Therefore, the method provides improved time efficiency and energy efficiency as compared to existing methods for preparing gels. Additionally, the method allows supercritical drying while avoiding a need for an additional solvent substitution, thereby simplifying the overall process. Further, the method enables preparation of carbon aerogels for supercapacitors having a high specific surface area and high capacitance even in the absence of additional activation step.

    Abstract translation: 公开了制备碳气凝胶和碳气凝胶的方法。 制备碳气凝胶的方法包括：将含有间苯三酚和糠醛的有机原料与能够以有规定比例溶解有机物质的溶剂混合形成溶胶溶液; 通过使用酸性或碱性催化剂充分调节溶胶溶液的pH，在室温下在大气压下胶凝溶胶溶液，并使所得凝胶老化; 用液态二氧化碳代替所得凝胶中的溶剂，然后以超临界状态干燥，形成有机气凝胶; 并在惰性气氛下在电炉中热解有机气凝胶，得到碳气凝胶。 特别地，通过充分调节溶胶溶液的pH，在室温下在短时间内形成凝胶。 因此，与用于制备凝胶的现有方法相比，该方法提供了改进的时间效率和能量效率。 此外，该方法允许超临界干燥，同时避免需要另外的溶剂置换，从而简化了整个过程。 此外，即使在没有额外的活化步骤的情况下，该方法也可以制备具有高比表面积和高电容的超级电容器的碳气凝胶。
