| 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２．９３ｕｍ、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 351.0m2-1 with the preparation condition of ［Ti］=0.82mol-1, ［Ti］/clay=20mmol-1, and has a good thermal stability to 860C |
