Abstract
The present invention involves micron-scale cerium oxide particles having a multi-cores single-shell structure, comprising: a cerium oxide shell, the shell being composed of crystalline and/or amorphous nano-scale cerium oxide particles; and a plurality of nano-scale cerium oxide grain cores aggregates located in the interior of the shell. Also involved is a preparation method for the micron-scale cerium oxide particle having a multi-cores single-shell structure. A supported catalyst with the micron-scale cerium oxide particles according to the invention as the support have good hydrothermal stability and good sulfur resistance, and the active components of the supported catalyst are not easily embedded, and the supported catalyst has a great application prospect in the field of catalytic oxidation of exhaust emissions such as CO, NO or volatile organic compounds.
