Designed synthesis, zeolite framework

Against the trend of using more complicated and expensive organic SDAs to produce new zeolite framework types, the CDM approach was initially proposed as a cheaper alternative for the designed synthesis of zeolites. The concept of CDM approach was first developed... 

Mesoporous molecular sieves materials5-8 designated M41S (which include the MCM-41 class of materials) have made a further major impact on the area of synthesis of porous materials. A variety of open framework structures that are mesoporous have recently been reviewed by Thomas.9 Activated charcoal, MCM-41, mesoporous tungsten oxide, and substituted MCM-41 materials are mentioned. This article primarily emphasizes potential applications of such materials and possible mechanisms of reaction. The mesoporous sysems are compared briefly to microporous materials such as zeolites, ALPOs, MeALPOs and SAPOs.
