Abstract
A silicon dioxide tetrahedron sheet having a specific morphology with the pseudomorphs of the starting raw material of clay minerals for the sheet is prepared, and this is reacted with an alkylonium salt whereby a desired number of the silicon dioxide tetrahedrons are removed from the sheet by the action of the micelles of the alkylonium salt formed on the surface of the sheet to thereby form mesopores in the sheet. The mesopore material of the sheet has phyllo-structured 6-membered skeletons as connected to each other, in which each one phyllo-structured 6-membered skeleton is formed by connecting 6 silicon dioxide tetrahedrons together, and its mesopores are formed by removing a desired number of the silicon dioxide tetrahedrons from the sheet.
