摘要：
Porcine pancreatic lipase (PPL) was immobilized in ordered mesoporous silica materials, which were using PEG 2000 (poly(ethylene glycol)) and P123 as dual templates and synthesized via hydrothermal process. The materials were silylated by (3 aminopropyl)triethoxysilane (APTES) by postsynthesis-grafting method. Samples were characterized by XRD, TEM, and BET. The results showed that the 2-dimensional hexagonal mesoscopic structure kept unchanging after modification. As compared to lipase immobilized mesoporous silica, the loading amount and hydrolization activity of lipase immobilized on aminopropyl-grafted mesoporous silica increased, respectively.
