摘　　要：介孔材料具有高的比表面积、高的孔体积、均一可调的孔径、有序的孔道结构以及易于表面功能化等优点,可广泛用于酶的固定化。介孔材料中酶的固定化方法主要包括物理吸附、物理包埋和化学吸附。综述了介孔材料中不同固定化酶方法的优缺点、酶的固定化影响因素及固定化酶的应用,并对固定化酶的发展前景进行了展望。Mesoporous materials can be widely used for enzyme immobilization due to their high specific surface areas,high pore volumes,and uniform with adjustable pore diameter,well-ordered pore structures,and easily being functionalized on the surface. Physical adsorption,physical encapsulation and chemical adsorption have been used to immobilize enzymes inside the mesopores of mesoporous materials. The advantages and disadvantages of these methods,the influence factors and application for enzyme immobilization are reviewed. The outlook of potential applications of immobilized enzyme is also expected.
