Mesoporous molecular sieve (MCM-41) was synthesized by two-step hydrothermal method. The synthesized mesoporous molecular sieve was characterized by XRD, TEM, and specific surface measurement. The resulting mesoporous molecular sieve was well long range ordering and had specific surface area more than 800 m 2 /g. The research on catalytic benzene hydrogenation on MCM-41-supported Pt showed that the conversion of benzene was higher than 95% and the selectivity of cyclohexane was up to 100% at a reaction temperature of 250 ℃ and reaction pressure of 3.0 MPa.
