The NO decomposition reaction on Cu ZSM 5/cordierite monolithic catalyst samples with different Si/Al ratios was carried out at 723 K and GHSV=10?000 h -1 with NO ( ω =2×10 -3 ) in He. The results indicated that a higher Si/Al ratio favors the conversion of NO. Little amount of N 2O was found in the products when the reaction temperature was over 623 K. The turnover frequency (TOF) for NO decomposition on the Cu ZSM 5/cordierite monolithic catalyst was higher than that on the pure Cu ZSM 5 zeolite catalyst.
