Microporous and mesoporous inorganic materials form the backbone of many heterogeneous catalysts and separations media. Because of the extensive commercial applications of these classes of materials, substantial efforts on the part of both academic and industrial researchers have been made to unlock the hidden secrets of the mechanisms of their formation and, through the exploitation of this understanding, to synthesize novel materials with important properties. Much of the mechanistic work has focused on understanding the role of organic directing or templating agents which play a complex, cooperative role of spatial ordering through the filling of void space, balancing charge, and stabilizing structural units. |
