主 题：Hollow-ZSM-5 Selective catalytic reduction Hydrothermal method NOx conversion
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 NOx conversion（90% NOx 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.
