Abstract： ZrMCM-41 mesoporous molecular sieves were successfully synthesized by microwave irradiation method and hydrothermal method by using sodium silicate as Si precursor, zirconium sulfate as Zr source, and cetyltrimethyl ammonium bromide as synthesis template. The samples were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and N2 physical adsorption, respectively. The thermal and hydrothermal stabilities of ZrMCM-41 mesoporous molecular sieves synthesized by two different methods were also investigated. The experimental results show that the samples obtained by microwave irradiation method and hydrothermal method, respectively, possess the typical hexagonal mesoporous structure of MCM-41. The specific surface areas and the average pore sizes of the resultant HZrMCM-41(hydrothermal method) and MZrMCM-41 (microwave irradiation method) samples are 89196 cm2／g, 256 nm, and 83035 m2／g, 247 nm, respectively. The mesoporous structure of the two ZrMCM-41 mesoporous molecular sieves still retain after calcination at 750 ℃ for 3 h or hydrothermal treatment at 100 ℃ for 6 d. However, the mesoporous ordering is poor.
