Preparation of multi-oxide (Cu-Mn) supported on alumina monolith catalyst by corona plasma method for CO oxidation reaction at low temperature
Abstract
In this study, multi-oxide catalysts (Cu-Mn) were prepared by corona plasma and wet impregnation methods. Characteristics of catalysts are determined by modern physicochemical methods such as: Infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermal analysis by thermal weighing (TGA - Thermogravimetric Analysis), observing the surface with transmission electron microscopy (TEM). All catalysts are determined to be active for the treatment of emissions through the oxidation of CO in the gas phase. The results showed that the use of corona plasma method for smaller particle size, uniform dispersion and higher specific surface area when compared with the wet impregnation methods. The activity of catalyst prepared by corona plasma method is also 20-25% higher than wet impregnation method.
