Abstract
The technology of liquid-phase synthesis of mesoporous xerogels and aerogels based on ZrO2–Y2O3–CeO2 is developed. Xerogels are obtained by the coprecipitation of hydroxides, while aerogels are obtained in accordance with the sol–gel technology: the average pore size is 1.5–17.2 nm and the specific surface area is 120–878 m2/g. Aerogels are characterized by a high degree of porosity: the pore volume attains 1–4 cm3/g. Based on precursor xerogels, nanopowders of a tetragonal solid solution of the (ZrО2)0.92(Y2О3)0.03(CeО2)0.05 composition with a particle size of 5–9 nm and S spec = 74 m2/g were fabricated. Due to the high values of their specific surface area, the synthesized xerogels and aerogels are promising as sorbents, catalysts, or catalyst supports.
