Here we report excellent NH3-SCR activities and N2 selectivities on Cu/SAPO-34 catalysts with comparison to Cu/ZSM-5 under the same reaction and aging conditions. The effect of hydrothermal/sulfur aging treatment on the catalytic performance of Cu/SAPO-34, kinetic and material characterization were investigated.
