摘要:

采用sol-gel法合成了含Ti多孔粘土材料,并利用XRD、IR、DTA等方法对其实验条件进行初步探讨.结果表明,sol-gel法比TiCl水解法更容易形成大孔结构,在[Ti]=0.82mol·L-1、[Ti]/±=20mmol·g-1的条件下,可得到层间开孔达2.93um、比表面351.0m~2·g-1的含Ti多孔粘土材料,材料在860℃之前具有较好的热稳定性.

Abstract: Titanium porous clays were synthesized by the reaction of Na-montmorillonite with Ti crosslinking agent prepared by sol-gel method. The preparation conditions of
titanium porous clay were also researched by means of XRD, IR and DTA etc. The results show that the product synthesized by sol-gel method is easy to form large
pore structure than by TiCl4 hydrolysis method, the resulting titanium porous clay possesses interlayer free spacing of 2.93nm and surface area of 351.0m2·g-1
with the preparation condition of [Ti]=0.82mol·L-1, [Ti]/clay=20mmol·g-1, and has a good thermal stability to 860℃.

Key words: sol-gel, TiO2, porous clay, clay nanocomposite
