摘　　要：Co β zeolites have been synthesized by hydrothermal method. The influence of synthesis conditions on the crystallization of Co β zeolites has been investigated. The Si/Co ratios and structure of the products have been characterized by means of chemical analysis, XRD, IR, DTA, TEM, ICP and UV vis diffuse reflectance spectra. The results show that the particles of Co β zeolites are well distributed. The unit cell parameters of the resulting Co β zealites are changed as compared with Al β zeolite due to the presence of Co in the framework of zeolite.Co β zeolites have been synthesized by hydrothermal method.
