When secondary building units characteristic of zeolite Beta detected by FT-IR appeared in the reaction mixture in the absence of crystals of zeolite Beta, the pre-treatment was terminated. The aluminosilicate gel with seconding building units characteristic of zeolite Beta was led to ordered-channel hexagonal mesoporous molecular sieve by the interaction between liquid-crystal micelles formed by the self-assembly of surfactants and pre-treated alumiosilicate gel. Therefore, the mesopore wall of SBU mesoporous materials showed the structural character of zeolite Beta.

当反应混合物出现用FT-IR可以检测到的Beta沸石次级结构单元且又没有生成Beta沸石晶体时，即刻终止预处理过程；然后利用表面活性剂超分子自组装形成的液晶胶团与经过预处理的无机物种通过界面作用把含有Beta沸石次级结构单元的无机物种导向为有规整孔道结构的六角中孔分子筛，这种SBU中孔材料的孔壁因而具有Beta沸石的结构特征。
