摘要：

ZSM-5 nanosheets with Si/Al molar ratios of 18, 26 and 95 have been synthesized hydrothermally using [C18H37-N+(CH3)(2)-C6H12-N+(CH3)(2)-C6H13]Br-2 as a template and then ion-exchanged with Cu2+ cations. The obtained Cu-ZSM-5 nanosheets were characterized by XRF, N-2 adsorption-desorption, XRD, SEM, TEM, DRIFTS, H-2-TPR, O-2-TPD and CO-DRIFT. Their catalytic performance for N2O decomposition was investigated. The catalytic activity in terms of TOF for Cu-ZSM-5 nanosheets increases with the decreasing of the n(Si)/n(Al), due to better reducibility of active Cu+ species, and better desorption capability of adsorbed oxygen on Cu-ZSM-5 nanosheets with lower n(Si)/n(Al).
