Effect of hydrogen peroxide detemplation on the structure and acid properties of MCM-56 zeolite

摘要：

　　MCM-56 zeolite has been synthesized by dynamic hydrothermal method.The template of as-made MCM-56 was removed by two methods.One is traditional calcination,the other is hydrogen peroxide post-treatment.All materials were characterized by different techniques,such as XRD,N2 adsorption-desorption,NH3-TPD and FTIR.Results show that the template of as-made MCM-56 could be removed effectively by hydrogen peroxide post-treatment.The topology of the hydrogen peroxide treated MCM-56 remains unchanged.The BET surface area and external surface area of MCM-56 zeolite could be obviously improved by hydrogen peroxide treatment.The amount of acid sites was increased by hydrogen peroxide treatment but the acid strength was not modified.
