采用纳米结构工程，通过双聚合物静电纺丝法制备了SO₄^2-/ZrO₂型固体超强酸中空纳米纤维，考察了纺丝液性质对纳米纤维形貌的影响，通过SEM、TEM、FT-IR、XRD、BET、酸度测定等对所制备的中空纳米纤维进行表征。结果表明，所制备的固体酸具有完整连续的中空纳米纤维结构，纤维壁上具有大量的孔结构，具备固体超强酸的特性。相较于共沉淀法制备的固体超强酸，中空纳米纤维具有更高的表面酸强度和比表面积，同时对质子传递具有更好的促进作用。

Solid super acids are widely used in various fields.However,their morphologies are hard to control and they commonly have very low specific surface area,resulting in a low mass activity.Nanostructure engineering can increase effectively the specific surface area and easily control the morphology,especially through electrospinning method.Taking nanostructure engineering,a SO₄^2-/ZrO₂ solid super acid hollow nanofiber is prepared by electrospinning of double polymers,and characterized by SEM,TEM,FT-IR,XRD,BET,acidity measurement etc.Meanwhile,the effect of spinning solution properties on the morphology of nanofibers is investigated.It is found that the prepared solid acid shows a complete continuous hollow nanofiber structure with lots of pores in the fiber wall,which resulting in a higher surface acid strength and specific surface area compared with the solid acid prepared by co-precipitation.Compared with solid super acid prepared by co-precipitation,this SO₄^2-/ZrO₂ solid acid hollow nanofiber possesses higher surface acid strength and larger specific surface area,and can promote proton transfer better.
