Zusammenfassung: | The invention discloses a Ti-MCM-41 mesoporous molecular sieve synthetic method. The method includes the steps of utilizing tetrabutyl titanate as a titanium source, adding hydrogen peroxide (H2O2) in synthetic mother solution as complexgin agents so as to restrain hydrolysis speed of titanate and directly synthetize Ti-MCM-41 in a household microwave oven. The Ti-MCM-41 mesoporous molecular sieve synthetic method solves the problems in the prior art that crystallization reaction time is long, hydrothermal stability is poor, particles are not uniform, operations are complex, and the like. On the condition of the full power of 700 W and 30% of power, the tetrabutyl titanate is subjected to intermittent reaction for 40 minutes, then is subjected to suction filtration, washing and drying, and then is subjected to calcination at 550 DEG C for 6 hours to obtain the Ti-MCM-41. A Ti-MCM-41 mesoporous molecular sieve prepared through the method is regular in skeleton structure, uniform in particles and high in heat s |
