Summary:The problem of CO[sub.2] waste in the atmosphere is a major concern, and methods of CO[sub.2] utilization are being currently developed. In the present work, a plasma-catalytic process is applied for CO[sub.2] dissociation. A series of MgO and CeO[sub.2]-containing catalysts were synthesized, and the samples were characterized by: a low-temperature N[sub.2] adsorption-desorption analysis, X-ray diffraction, X-ray photoelectron spectroscopy, temperature-programmed desorption of CO[sub.2], and X-ray fluorescence spectroscopy. It was stated that under dielectric barrier discharge conditions, the catalyst surface, composition, and phase content remain unchanged. The superior catalytic activity of the MgCe-Al sample is attributed to the combination of weak basic sites and oxygen vacancies on the catalyst surface.
