Nanostructured Catalysts for Removal of Carbon Monoxide from Gaseous Media
https://doi.org/10.18412/1816-0395-2012-7-25-27
Abstract
There are synthesized nanostructured solid solutions of Me-Zr-Ce-O (Me = Sc, Y, La, Pr, Nd, Sm) based on the cubic fluorite lattice of ceria. By the methods of X-ray fluorescence analysis, BET and gas chromatography, there are studied structural and catalytic properties of the samples. The catalysts have high catalytic activity and thermal stability, which indicates the possibility of their use in the process of detoxification of gaseous media from carbon monoxide.
