| Research Abstract |
The present group has found the new type of acid-type catalysis on mesoporous silica. In this study, the acid catalysis was characterized in details and then combined with metal ions. At first, the acid catalysis was investigated as a function of the pore diameter, the shape of the pore, and a surface aluminum ion as an impurity. The volcano-shaped dependence of the catalysis was clearly found on the pore diameter and was not dependent on the kinds of reactants, indicating that the surface acidity resulted from the pore structure. Next, the combination of the acidity with a copper ion resulted in the catalysis for the selective aryl formation, which was the first example reported on copper except for the catalysis on Pd. At last, nickel ion-loaded mesoporous silica, in which nickel ion was supported using the template ion exchange method, was found to show a catalytic activity for the conversion of bio-ethanol to propene. The reaction pathways were also suggested.
