Abstract

We report for the first time a novel bimodal mesoporous crystalline ceria with nanometer-sized, pseudo-spherical, monodisperse particles. This mesoporous ceria was prepared using block-copolymer templates and non-aqueous solvent. The surface areas, mesopore structure and thermal stabilities of the final product are found to depend on the gel composition. The material shows very high sorption and catalytic properties for the elimination of acetaldehyde compared to semicrystalline mesoporous ceria and non-porous crystalline ceria materials. The material also showed acetaldehyde elimination ability twice as high as that of conventional materials.
