The developments in the area of ordered nanoporous solids have exceeded the traditional catalytic and separation uses and gave rise of a wide variety of new applications at different branches of chemistry, physics, material science, etc. The outstanding activity in this area is due to the outstanding properties of nanoporous materials that focus the attention of researchers from different communities. However, recent achievements in a specific field often remain out of the focus of collaborating communities. Present review book is a multi-author work summarizing last developments and prospects in the area of ordered porous solids, including synthetic layered materials (clays), microporous zeolite-type materials, ordered mesoporous solids, metal-organic-framework compounds (MOFs), carbon, etc. All aspects, from the synthesis via the comprehensive characterization to the advanced applications of ordered porous materials are revised. The chapters are written by leading experts in the respective fields with an emphasis on the recent progress. Thus, the book present the art of ordered porous solids in the dawn if 21 century.
