A classical approach to the production of carbon aerogels by pyrolysis of organic resorcinol–formaldehyde aerogels has been studied. Organic aerogels with a density of no more than 0.17 g/cm3 and a specific surface area of up to 632 m2/g have been obtained. The corresponding carbon aerogels had a density of no more than 0.20 g/cm3, while their specific surface area reached 757 m2/g. The effect of important synthetic parameters—the concentration of the catalyst and the aging time of the precursor gel—on the features of the porous structure and the value of the specific surface area is demonstrated. For the first time, such an effect has been studied in detail for the size distribution of meso- and micropores.

使用用于间苯二酚-甲醛前体-凝胶形成的不同参数获得的有机气凝胶和碳气凝胶的结构特征

已经研究了通过热解有机间苯二酚 - 甲醛气凝胶生产碳气凝胶的经典方法。已获得密度不超过0.17 g/cm3、比表面积高达632 m2/g的有机气凝胶。相应的碳气凝胶的密度不超过 0.20 g/cm3，而其比表面积达到 757 m2/g。证明了重要的合成参数——催化剂的浓度和前体凝胶的老化时间——对多孔结构特征和比表面积值的影响。这是第一次详细研究了中孔和微孔尺寸分布的这种效应。
