The surface chemistry of three different copper based systems (Cu-ZSM5, Cu-ETS10 and Cu-silica-alumina) prepared with different copper loadings has been studied by adsorption microcalorimetry of NO and CO. The reducibility and regeneration of the Cu2+ ions and copper oxide crystals were studied by TPR-TPO experiments. The catalytic activity for NO reduction with hydrocarbons in oxidizing atmosphere appeared to depend on the nature and dispersion of the copper species.

Abstract
The surface chemistry of three different copper based systems (Cu-ZSM5, Cu-ETS10 and Cu-silica-alumina) prepared with different copper loadings has been studied by adsorption microcalorimetry of NO and CO. The reducibility and regeneration of the Cu2+ ions and copper oxide crystals were studied by TPR-TPO experiments. The catalytic activity for NO reduction with hydrocarbons in oxidizing atmosphere appeared to depend on the nature and dispersion of the copper species.
