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.
