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.]
