The results are as follows: ( 1) Microspheres SiO2 were prepared by hydrolysis of tetraethoxy silane ( TEOS) in alcohol-water mixed solvents using ammonia as catalyst.
研究结果如下:(1)利用St(o¨)ber法,以醇为溶剂,正硅酸乙酯在氨水催化下水解、缩聚,并进行一系列的后处理得到SiO2微球。
A simultaneous synthetic template carbonization method ( SSTCM), where tetraethoxy silane ( TEOS) was used as the source of the silica template and resorcinol-formaldehyde gel as the carbon precursor, was suggested for the preparation of mesoporous carbons with a controllable pore structure.
以正硅酸乙酯为模板硅源,间苯二酚甲醛凝胶为炭前驱体,采用同步合成模板炭化(SSTCM)法制备了具有可控结构的中孔炭材料。
