Abstract:
UV-vis spectra, XRD, H-2-TPR, TEM and ESR were used to characterize a series of Cu/gamma-Al2O3 catalysts, which were prepared by incipient wetness impregnation using copper nitrate, copper acetate or copper sulfate as precursors, to study the role of Cu species on Cu/gamma-Al2O3 catalysts for NH3-SCO reaction. It was found that the mixture of CuO phase and CuAl2O4 phase formed on various Cu/gamma-Al2O3 catalysts, and the Cu species and dispersion had significant influence on the Cu/gamma-Al2O3 activity. Highly dispersed CuO phase on the support would be related with its high activity for the NH3-SCO reaction. (C) 2011 Elsevier B. V. All rights reserved.
