Condensed state chemistry, as we know, means diverse chemical processes taking place in liquids and solids. Actually, condensed state chemistry is present throughout the synthesis and preparation of inorganic materials, especially the nano- and porous solid materials. In the material synthesis, obtaining target solids with desired chemical compositions and phase structures, is probably one of the most fundamental issues of condensed state chemistry. While in the synthesis of porous solid materials such as microporous zeolites or mesoporous oxides, the regulations of pore structures along with the chemical compositions and phase structures become important. Moreover, aiming at the applications in, e.g., catalysis and drug delivery, key factors such as the active sites and defects, and the geometric/physical features such as the dimensions, dispersity and morphologies, should be taken into considerations in addition to the issues mentioned above. In this feature article, by focusing on the inorganic oxides, we discuss several aspects of condensed state chemistry in the chemical syntheses of nanoparticles and superfine powders, pore structural regulations of mesoporous materials and composites, and the synthesis and catalytic properties of hierarchically porous structured zeolite, so as to acquire further in-depth understanding of condensed state chemistry in the materials synthesis and promote the development of nano-/porous inorganic solids under the guidance of condensed state chemistry.
