摘要

A combined spectroscopic and catalytic study on the activity and hydrothermal stability of copper-exchanged MCM-22 and ZSM-5 zeolites is reported;CuMCM-22 is active in the decomposition of NO and N_2O also in the presence of water,whereas CuZSM-5 deactivates rapidly upon steaming.CO adsorption on fresh and steamed samples enlightened that the copper active species are more stable on CuMCM-22.
