Pure silicon MCM-41 mesoporous molecular sieves was synthetized through Hydrothermal.A series of different Si/La （mole） of the LaAc/MCM-41 （LaAcM） mesoporous molecular sieve was prepared through microwave scattering. The crystal structure and surface property of mole-cular sieve were characterized by the XRD, IR, and N2 adsorption desorption and so on. The results showed that loadded n （Si）：n （La） = 30：1.0, organic acid group content of LaAcM was 0.20mmol/g by hammett. H0 was between ＋6.8 and ＋4.6. The BET surface area of LaAcM was 1 287 m2·g^-1 with the pore volume of 0.827 3 cm3.g^-1 and pore size of 2.571 nm. Samples possessed typical hexagonal symmetry mesoporous material.
