Abstract:

Epoxy group-functionalized periodic mesoporous organosilicas(FPMOs) was synthesized by the co-condensation of 1,2-bis(triethoxysilyl) ethane(BTESE) and 3-glycidoxypropyltrimethoxylsilane(GPTMS) in the presence of triblock copolymer poly(ethylene glycol)-b-poly(propylene glycol) -b-poly (ethylene glycol) (P123) under acidic conditions and utilized as a support for laccase immobilization. The effect of epoxy group-functionalization on the immobilization of laccase and the stability of immobilized laccase were investigated in detail. The level of functionalization, the pore structure and the laccase immobilization were detected by means of solid-state NMR, N-2 adsorption and UV-Vis, respectively. It is revealed that epoxy groups are successfully attached covalently to the pore wall of PMOs and the functionalized materials retain a desirable pore structure. Laccase immobilized on functionalized FPMOs exhibits a higher activity and stability than that adsorbed on pure PMOs.
