摘要：

以三嵌段共聚物Pluronic P123和正丁醇为结构导向剂，正硅酸乙酯为硅源，钛酸丁酯为钛源，利用水热合成法制备钛掺杂KIT-6介孔分子筛.反应物TEOS，TBOT，P123，HCl，BuOH，H2O的物质的量比为1∶0.014~0.1∶0.017∶1.0~3.0∶1.31∶195.通过XRD，BET，FT-IR和UV-Vis表征制备得到的材料.结果表明，掺钛量对原立方相的骨架结构和结晶度的影响显著.同时研究了制备Ti-KIT-6(20)时盐酸加入量对其结构的影响.

Abstract:

Titanium incorporated mesoporous KIT-6 molecular sieves were synthesized by direct hydrothermal method using Pluronic P123 and n-butanol as the structure-directing mixture,tetraethylorthosilicate (TEOS) as the silica source and tetrabutyl titanate (TBOT) as the titanium source.The mole ratio of TEOS,TBOT,P123,HCl,BuOH,H2O,was 1∶0.014~0.1∶0.017∶1.0~3.0∶1.31∶195.The materials were characterized using XRD,BET,FT-IR and UV-Vis.The amount of titanium content influenced the framework structure and crystallinity of the Ia3d phase significantly.The effect of the amount of HCl on the structure of Ti-KIT-6 (20) was also studied.

Key words: titanium, KIT-6, framework structure, crystallinity, preparation, characterization
