以硝酸锆为锆源，以阴离子表面活性剂十二烷基硫酸钠（SDS）为模板剂，S2O8^2-浸渍无定形Zr（OH）4，制得介孔S2O8^2-／ZrO2固体超强酸，通过N2吸附－脱附、XRD分析、Hammett非水滴定、TEM等方法，考察了不同焙烧温度对S2O8^2-／ZrO2介孔超强酸晶体结构、酸强度等性能的影响。结果表明，当焙烧温度600℃，S2O8^2-／ZrO2样品比表面积为140m2／g，平均孔径在3～4nm之间，酸强度H0≤-12．7，为介孔相固体超强酸。

Zirconium nitrate as the source, zirconium with anionic surfactant sodium dodecyl sulfate （SDS） for template, the amorphous Zr（OH）4 was dipped with S2O8^2-, then the mesoporous S2Os2-/ZrO2 solid superacid obtained, with the N2 adsorption-take off, XRD analysis, Hammett non-aqueous titration, TEM and other methods, inspecting the effects of the different roasting temperature to S2O8^2-/ZrO2 of its crystal structure, acid strength and other performance. The results show that, when the sample＇ s surface area is 140 cm2 / g when its roasting temperatureget 600℃. For, the average aperture for 3-4nm, Ho≤-12.7. Then the S2O8^2-/ZrO2 mesoporous e solid super acid received.
