摘要: Abstract Cu-ion-exchanged iron-pillared interlayer clays (Fe-PILCs) were prepared under different pH conditions to analyze the influence on distribution of copper species over their structure, and catalytic performance for selective reduction (SCR) NO x by propene. It was observed that those samples without control, as isolated Cu 2+ ions. When acid pH, activity decreased an appreciable CO production observed, likely due low amount cations in catalysts. Finally, alkaline ions CuO clusters. Their tests showed best results SCR . The presence led improvement yield N 2 With a study situ FTIR NO, reaction mechanism has been proposed, where intermediates are mainly acetates, organic nitro compounds nitrous oxide species.
