Abstract: |
Mesoporous zirconia samples with high thermal stability were synthesized by hydrothermal homogeneous precipitation method using an anionic surfactant as template.In this method,sodium dodecyl benzene sulfonate(SDBS) not only functioned as a directing agent for mesoporous structure but also functioned as a mesoporous structure stabilizer with the sulfonic groups converted to SO2-4after calcination.The samples were characterized by TEM,nitrogen adsorption-desorption isotherms,XRD and FT-IR.The N2 adsorption analysis showed that the zirconia still has a surface area of 156 m2/g after calcination at 500 ℃.The TEM analysis displayed that it has a worm-like mesoporous structure with a pore size about 2.9 nm.The XRD analysis displayed that the prepared zirconia continuous to present a pure tetragonal phase,with good thermal stability even calcinated at 600 ℃. |
