A novel method to synthesize microporous materials or micro-meso-porous composite materials by use of mesoporous silica materials as a source, was developed as a suitable technique to obtain a hierarchical porous network. Another synthesis strategy for the newly-functionalized porous materials was also proposed; where hetero-atom doping on the surface of mesoporous silica materials in their synthesis or post-syntheis procedure, was carried out, and then the mesoporous materials were transferred into microporous materials without loss in the surface nature. As a result of this work, fabrication of a group of hierarchical porous silica from micro- through macropore with an important catalytic function of surface such as acid-base or redox properties, was successfully achieved.
