Investigation of Cu Species in CuBTC: Active Sites for Selective Catalytic Reduction of NO with NH₃

Article Preview

Abstract:

The classical metal-organic Frameworks CuBTC showed remarkable low temperature activity in selective catalytic reduction of NO with NH₃ (NH₃-SCR). It was found the conversion of NO can reach as high as 100% in the range 210-300 °C on the activated sample. The nature of the active Cu species among CuBTC in NH₃-SCR based on the activity data were characterized by TEM, XPS, XRD, EPR and IR. This high activity is not only due to the unsaturated metal centers of the frameworks, but also to the presence of high-dispersed Cu₂O particles. Both Cu²⁺ and Cu⁺species are the active sites for NH₃-SCR.
