全氟烷基超酸(磺酸RfSO3H,磺酰亚胺(RfSO2)2NH和磺酰基甲烷(RfSO2)3CH)比普通强酸(RSO3H等)表现出更强的酸性和更优秀的催化活性,固载化能提供高效的绿色催化途径.尤其无机载体SiO2负载固体酸,同时具备有机材料和无机材料的优点,比表面大、热稳定性好、酸位点有效、结构/织构可调可控.本文综述了上述三类超酸的固载化研究及催化应用,并讨论了固体酸更广阔的研究和应用领域.%A series of superior green catalyst could be obtained by supporting perfluoalkyl organic super acid ( RfSO3H, ( Rf SO2)2NH and ( Rf SO2 ),CH, Rf = perfluorinated alkyl) due to their stronger acidity and higher catalytic activity than RSO3H. Especially,the immobilization of organic acids to SiO2 could be accomplished with some merits of design:excellent thermo-stability,accessible acid sites,and avenues to recovery,possibly recyclability. In this review,we described the preparation and catalysis applications of the three kinds of supported perfluoalkyl organic acid,and the facing opportunities in the field were discussed.
