摘　　要：全氟磺酸树脂是绿色固体酸催化剂,对许多反应有较好的催化活性和选择性。但由于全氟磺酸树脂比表面较低,埋没在氟碳基体中的酸性中心不易被反应物所接近,质量比活性低。本文对近年来新形态全氟磺酸树脂,如多孔、负载化、纳米复合物及其改性的全氟磺酸树脂的催化作用进行了综述,文献结果表明全氟磺酸树脂纳米复合物对很多有机合成反应具有很高的催化活性。Perfluorinated resinsulfonic acids are efficient and versatile heterogeneous acid catalysts.They have the disadvantages that their surface areas are very low in comparison with those of more common solid acids and their acidic sites are not readily accessible to the reactants.The catalyst utility of perfluorinated ion-exchange polymers containing pendant sulfonic acid groups,supported and unsupported,has been broadly reviewed.With the resin being mechanically entrapped within the silica network and not merely on the surface of a support,the catalytic activity of the resin/silica nanocomposite catalysts is significantly increased.
