Abstract
Mesoporous zirconia microspheres were prepared by a sol-gel method using F127 and sodium dodecyl sulfate (SDS) as templates. The effects of calcination temperature and the content of templates on the structure and properties of mesoporous microspheres were studied. Results show that the size of microspheres is uniform, with diameter of about 900 μm. It is found that with the increase of the calcination temperature, the specific surface area of the sample decreases, while the average pore diameter increases. After calcined at low temperature, the samples are pure tetragonal zirconia, and monoclinic phase appears after calcination at 600℃. With the same calcination temperature, the specific surface area and pore volume of the sample with more templates are larger. The addition amount of templates has no influence on the phase structure of the samples.
