采用纳米铸造方案,在盐酸介质中,以咪唑盐类离子液体为模板剂,正硅酸乙酯为前驱体,合成了一系列介孔或超大微孔氧化硅整体材料,详细考察了盐酸浓度、盐酸用量和前驱体用量对材料结构参数的影响.结果表明,随盐酸浓度的升高,材料孔体积和孔径呈大致减小的趋势;随TEOS用量的增加,材料孔体积和孔径依次减小.材料大都具有高的比表面积和均一的孔径. A series of mesoporous or very large pore silicon oxide monolithic materials were synthesized by using nanometer casting scheme in hydrochloric acid medium using imidazolium salt ionic liquid as templating agent and tetraethyl orthosilicate as precursor. The effects of hydrochloric acid concentration, The amount of hydrochloric acid and the amount of precursor on the structure parameters of the material.The results show that with the increase of hydrochloric acid concentration, the pore volume and pore size of the material tends to decrease. With the increase of TEOS dosage, the pore volume and pore size decrease. Most materials have high specific surface area and uniform pore size.
