Zeolite and molecular sieves materials

It is known that temperature is a critical factor for the crystallization of zeolites and molecular sieve materials. Since the mesoporous structures can be formed in a wide range of temperature [2], it is essential to investigate a suitable range of temperatures for the formation of integrated MCM-41 structures in fluoride medium. 

Zeolites and molecular sieve materials exhibit fascinating properties particularly as sorbents or catalysts. From a fundamental point of view, they represent a family of crystallographically well-defined solid materials (this is not always the situation for most of the metallic oxides). When considering catalysis, two main factors play an important role, i.e., the nature of the active sites (particularly acidic sites) and the topology (cavities, channels, pores. ..).
