Effect of Hydrogen Peroxide Detemplation on the Structure and Acid Properties of MCM-56 Zeolite

Abstract:

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.
