Abstract
The CuO/Ce0,62Zr0,38O2 catalysts with different Cu loading were prepared by incipient wetness impregnation. The amount of Cu was 2, 4, 10 wt%. The samples were characterized by X-ray diffraction, scanning electron microscopy (SEM/EDX), N2 adsorption and Raman spectroscopy. The acid and redox properties of these catalysts were evaluated by isopropyl and t-butyl alcohol conversion. The isopropyl alcohol conversion showed that all Cu/CZ catalysts possessed higher activity than pure CuO and unmodified CZ support in dehydrogenation to acetone. The strong interaction of the active phase with the support is responsible for this rise of activity. Conversion of t-butyl alcohol confirmed the presence of acid centres. It was found that the increase in the activity of Cu/CZ catalysts compared with the unmodified CZ support is caused by the CuO active phase.
