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TiCl4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2.93nm、比表面351.0m2·g-1的含Ti多孔粘土材料，材料在860C之前具有较好的热稳定性.

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 351.0m2-1 with the preparation condition of ［Ti］=0.82mol-1, ［Ti］/clay=20mmol-1, and has a good thermal stability to 860C
