Abstract

Mesoporous silica was used as a support to immobilize enzyme （laccase） that were important in chlorphenol degeneration research. To biomimetically synthesize the mesoporous silica with an ordered three-dimensional （3D），hexagonal structure，cationic surfactants，alkyltrimethylammonium bromides （CnTAB，n = 12，14，16，and 18） with different chain lengths and an amphoteric biological surfactant，Sodium N-dodecyl glycine （YCS），were used as mixed templates in a mixture of H2SO4 as the acid source and tetraethyl orthosilicate（TEOS） as the silica source. The biomimetic synthesizing was successful. Compared with traditional mesoporous silica support，the 3D hexagonal mesoporous silica had a larger pore diameter （5 - 10 nm） and surface area. The adjacent pore channel occurred pore link. Using C16TAB or C18TAB along with YCS as mixed templates，mesoporous silica with a pore diameter of about 9 nm was obtained. Mesoporous silica with different morphologies and large pore diameter also provided excellent support for immobilizing laccase.［Ch，8 fig. 2 tab. 22 ref.］
