AbstractMesoporous materials with large pore size are much in demand for the reactions involving large molecules. However, their applications are limited by the weak acidity as compared with that of microporous zeolites. In this paper, a novel method was developed to synthesize strong acidic mesoporous materials. Cheap inorganic salts were used to synthesize Zr- and Ti-modified silica-alumina mesoporous materials and supported Pt electron-acid bifunctional mesoporous materials by ultrasonic sol-gel method without any types of templates or pore-regulating agents. The samples were characterized by pyridine adsorption and desorption, IR spectroscopy, XPS and H-2-TPR. Their catalytic performance was evaluated by using hydroisomerization reaction of 1-hexene. Pyridine adsorption-desorption and IR spectroscopy indicate that these samples have strong surface acidity. The XPS and H-2-TPR results suggest that the interactions between platinum and the supports exist in the samples. Hydroisomerization reaction of 1-hexene shows that the samples have high catalytic activity. It is concluded that their strong surface acidity results from the interactions between metal and the supports.
