Abstract A series of Beta zeolites has been carefully prepared by the conventional hydrothermal method under various ratios of H2O/SiO2 ranging from 10 to 60. These zeolite materials are thoroughly characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption-desorption, temperature programmed desorption of ammonia (NH3-TPD) and etc. It reflects that the water concentration (H2O/SiO2 ratios) has great impact on the zeolites nucleation and growth rates, resulting in the different crystals morphologies, size distributions and textural properties for the obtained Beta zeolite materials. These primary results are very help for guiding rational design of the zeolite catalysts with different topologies and other related materials for specific applications.
