摘要
采用十六烷基三甲基溴化铵作为有序介孔模板剂和相分离诱导剂,通过相分离和溶胶-凝胶转化,合成了具有较小有序介孔和较大堆积介孔/大孔的双重孔结构SiO2.结果表明,采用该双重孔结构SiO2 吸附模型生物大分子,其吸附量明显高于单一孔结构MCM-41 型SiO2,显示双重孔结构SiO2 吸附大分子的优势.
Abstract
Bimodal silica materials with ordered smaller mesopores and aggregated larger meso/macropores were synthesized based on phase separation and sol-gel transition by using cetyltrimethylammonium bro-mide as ordered mesopore template and phase separation inducer.The result showed that using the bimod-al silica to adsorb model biomacromolecules,the adsorption amount was significantly higher than that of unimodal MCM-41,showing the advantages of the bimodal silica in adsorbing macromolecules.
