Abstract: Using urea as homogeneous precipitant, the precursor of mesoporous zirconia was synthesized by hydrothermal method. After heat-treatment at 500~550 ℃ for 2 h, the crystalline (t or m phase) mesoporous zirconia with short-range order was prepared. Their BJH desorption pore size and BET surface area are about 4~6 nm and 60~90 m2•g-1, respectively.

Key words: Mesoporous zirconia, Urea, Hydrothermal, Uniform deposition
