Zeolite Synthesis: Can It Be Designed?

The possibility of designing zeolites by their controlled synthesis is discussed. The feasibility of creating pore architectures through the design of organic structure-directing agents is described for high-silica zeolites. The first example of such a design is presented. A strategy for building pure-silica zeolites from molecular precursors is outlined. It is concluded that the total design of zeolite structures through their designed synthesis is not currently obtainable but information providing "pieces to this puzzle" are quickly being assembled.
