Abstract
Method of coprecipitation with a subsequent thermal treatment was used to synthesize highly dispersed Mn2O3-Bi2O3-ZrO2-CeO2 solid solutions. The elemental and phase compositions, texture characteristics, dispersity, and morphology were examined. The thus synthesized samples exhibit a high activity in the reaction of CO oxidation. It was shown that the nature of doping ions (Bi3+, Nd3+, Sn3+, Gd3+) affects the catalytic activity of the materials. The highest catalytic activity was observed for the Gd0.05Bi0.05Zr0.18Ce0.72O2 sample.
