Sonochemical synthesis of mesoporous GdxZryTizCe1−x-y-zO2 solid solution

GdxZryTizCe1−x-y-zO2 (x+y+z≤0.3) solid solutions with a crystallite size of 5-10 nm have been prepared by the sonochemical method from inorganic salts without any additives. In all cases, ceria based materials exhibited a mesoporous structure with polymodal pore size distribution with diameter of 2-10 nm. It was shown that crystallite size and specific surface area remained practically unchanged while changing the dopant concentration.
