摘要/Abstract

摘要： Hollow-ZSM-5 was synthesized by a traditional hydrothermal method without alcohol, and a novel nano-sized Ce-Cu/hollow ZSM-5 sample was prepared by conventional incipient wetness impreganation. The catalysts were characterized by TEM, SEM, XRD, NMR and N₂ adsorption-desorption. The results indicate that the hollow-ZSM-5 has a good MFI structure with large surface area. The synthesized CeO₂-CuO/hollow ZSM-5 showed an excellent catalytic activity for NO_x conversion(90% NO_x conversion were obtained) in the temperature range of 340-550℃ under GHSV=480000 mL·g^-1·h^-1 due to its appropriate redox ability and acidity.
