Synthesis of nanostructural silica using quaternary ammonium salt of lignin as template
Cationic surfactant,quaternary ammonium salt of lignin,was synthesis from the lignin and trimethylamine though Mannich Reaction.Then quaternary ammonium salt of lignin was used as a novel template to prepare nanostructural silica from TEOS by sol-gel templating method.After removing the template at 580℃,nanostructural silica were obtained.The results of SEM and TEM show that there were two kinds of the silica after calcined.One is 3-dimetional macroporous silica,with the pore size of 100-200 nm.The other kind of silica is nanoparticle: the particle sizes range from 20 to 200nm and the specific surface area is 387.6 m2·g-1.
