Rapid synthesis of MCM-48 mesoporous molecular sieve at low cost of CTAB surfactant

By hydrothermal synthesis method,the thermally,hydrothermally stable and long-range ordered MCM-48 mesoporous molecular sieve was successfully prepared in short time at high temperature through the optimized synthesis conditions.The influences of the CTAB surfactant amount,crystallization temperature,crystallization time and the order of adding CTAB and NaF on the formation of MCM-48 were systematically studied here.The products were characterized by powder XRD and SEM.The results show that with the mole ratio of CTAB/Si=0.1,F-/Si=0.1,the high quality of MCM-48 mesoporous molecular sieve was synthesized at 423 K for 12 h.
