چکیده:

Since the discovery of M41S mesoporous molecular sieves, these materials have drawn tremendous attentions from various research fields. Among them, MCM-48 seems more attractive because of its unique three-dimensional pore structure [1-4]. The three important members of the M41S family are one-dimensional hexagonal MCM-41, three-dimensional cubic MCM-48 and unstable lamellar MCM-50. They have excellent structure characteristics such as controllable pore size between 2 and 10 nm and large BET surface area up to 1000 m2. There are few reports on the heteroatom-substituted MCM-48, In consideration of the great potential applications of cerium-substituted MCM-48
