| Abstract: | A series of superior green catalyst could be obtained by supporting perfluoalkyl organic super acid(RfSO3H,(RfSO2)2NH and(RfSO2)3CH,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 thermostability,accessible acid sites,and avenues to recovery,possibly recyclability.In this review,we described the preparation and catalysis applications of the three ki... |
