摘要

Mesoporous silica with a novel structure (FDU-11) has been prepared for the first time by using a rigid bolaform tetra-head-group quaternary ammonium surfactant: [(CH₃)₃NCH₂CH₂CH ₂N(CH₃)₂CH₂(CH₂) ₁₁OC₆H₄C₆H₄O(CH ₂)₁₁CH₂N(CH₃)₂CH ₂CH₂CH₂N (CH₃)₃] ⁴⁺·4Br^- under an alkaline condition. X-ray diffraction (XRD) and transmission electron microscope (TEM) studies show that the mesoporous silica FDU-11 may have a low symmetric tetragonal mesostructure with P4/mmm space group. N₂ sorption isotherms show that calcined mesoporous silica FDU-11 has the BET surface area of 281 m²/g, pore size of 2.05 nm and the pore volume of 0.36 cm³/g. A phase transformation from FDU-11 into another unknown mesoporous silica structure by a hydrothermal treatment is observed, suggesting the intermediate nature of the FDU-11 mesophase.
