英文摘要Supercritical CO2 modified with a methanol/dichloromethane mixture was used to quantitatively remove the template molecules (cetyltrimethylammonium bromide) from the pores of assynthesized pure siliceous MCM-41 in a flow apparatus. The resulting mesoporous MCM-41 materials, characterized by powder X-ray diffraction, nitrogen adsorption, and high-resolution transmission electron microscopy, exhibited higher surface areas, larger pores, and narrower pore size distributions than those obtained by conventional calcination at high temperature. The removed template retained its structures and properties and could be reused in the synthesis of MCM-41 materials.
