Synthesis and Characterization of Yttria-Doped Mesoporous Zirconia

Abstract

The yttria-doped mesoporous zirconia was successfully synthesized by evaporation induced self-assembly (EISA) method, and the microstructure and textural properties of the as-made product were studied extensively. The results showed that the as-made product possessed crystallized framework walls and a worm-like mesopore with a narrow pore distribution. The BET specific surface area and pore volume of the as-made product calcined at 500°C are 111 m2/g and 0.16 cm3/g respectively, and the corresponding data changed to 73 m2/g and 0.052 cm3/g after calcined at 700°C, which indicated that the as-made yttria-doped mesoporous zirconia possess a higher thermal stability.
