The discovery of periodic mesoporous materials with one and three-dimensional channels in early1990s has opened wide range of opportunities in porous solids. The development of such materials of well-defined geometry with precise and easily controllable pore shape and size is of great importance in many areas of modern science and technology. Mesoporous molecular sieve materials are new generation ordered nanoporoussolids, analogous to microporous (zeolitic) molecular sieves, having high surface area, large pore opening and huge pore volume. On one hand, the unique flexibility in terms of synthetic conditions, pore size tuning, high surface area, large internal hydroxyl groups, framework substitution, etc. have created new avenues not only in catalysis but also in the areas of advanced materials, environmental pollution control strategies, and separation processes. On the other hand, the preparation of high quality materials with designed pore structures is of paramount importance for many applications in areas including nanomaterials, catalysis, adsorption and separation. In designing such materials, several characteristics of pore structure may be addressed, which include their shape, size, and interconnectivity. In this presentation, the recent progress on the development of numerous nanoporous materials including hierarchical structures and their applications will be discussed.
