摘要
以正硅酸乙酯为无机模板硅源,蔗糖为炭前驱物,采用溶胶-凝胶法制得了比表面积达1073.36m2/g,孔径分布集中,平均孔径为2.75nm的中孔炭材料,并采用FT-IR、N2吸附、TG-DTA和XRD等分析手段对其进行了表征。
Mesoporous carbon materials was prepared using TEOS as templet and sucrose as carbon precursor through the sol- gel method. N2 adsorption at 77 K, FT- IR, TG- DTA and XRD were used to characterized the mesoporous carbon materials. The results showed that specific surface area and average pore size of the mesoporous carbon materials were 1073. 36 m^2/g, and 2.75 nm respectively , and their pore size distribution was very concentrative. The three - dimensionally interconnected silica structure effectively functioned as the template for the porous carbon materials.
