Abstract: Vinyl-functionalized MSU-X silicates were prepared by one-pot synthesis methodology at the pre-sence of Tx-15 and AEO9 surfactants respectively. The solids were characterized by XRD, FT-IR, 29Si MASNMR, HRTEM, SEM, N2 physisorption techniques. The surface morphology and textural properties of such materials varied with the synthesis mechanism and content of vinyl groups in the channel. The effects of the organic groups on the modified MSU-2 were investigated carefully. The vinyl-modified mesopore with 10％(x) VTES templated by AEO9 was of 3.1nm pore diameter, but that templated by Tx-15 displayed a bimodal mesoporous channels, in which the smaller pore size was about 3 nm, while the bigger one was in the range of 40～46 nm.
