| Abstract: | The selective reduction of NO by C3H8 is performed on copper-based catalysts: Cu/Al2O3, Cu/SiO2, Cu/SiO2–Al2O3 solids, fresh and hydrothermally-treated Cu-MFI with various Si/Al ratios. For all the Cu-MFI solids and for the non-zeolitic
supported-copper solids with low copper loadings, O2 promotes the reduction of NO. The C3H8–NO reaction rate correlates with the number of accessible and isolated Cun+ ions deduced from the infrared spectroscopy of adsorbed CO. When only one type of sites is detected, the FTIR spectroscopy
of adsorbed CO allows an estimation of the copper dispersion.
