NOx selective catalytic reduction by ammonia over Cu-ETS-10 catalysts
Translated Abstract
Ion exchange method was used to fabricate Cu-ETS-10 titanosilicate catalysts, which possessed high activity, N2 selectivity and SO2 resistance for NOx selective catalytic reduction (SCR). N2 sorption measurements indicated that the microporous catalysts had high surface areas of 288-380 m2/g. The Cu content and speciation were investigated by inductively coupled plasma atomic emission spectrometry, H2 temperature-programmed reduction, and diffuse reflectance infrared Fourier transform spectroscopy. Various Cu species coexisted within the catalyst. Isolated Cu2+ species were the active sites for NH3-SCR, the number of which initially increased and then decreased with in-creasing Cu content. The catalytic activity of Cu-ETS-10 depended on the isolated Cu2+ species con-tent.
