Calcination of molecular sieves by simple technique enhancing thermal stability of novel nanoporous material

Calcination is an important process to remove the template to open the pores of molecular sieves. The calcination process is difficult when the interaction of the template with the framework of molecular sieves is too strong. In some cases, it breaks the framework and reduces the thermal stability and crystalline nature of materials. During this investigation, the template molecules swift out from the pores when calcination at lower temperatures without breaking the framework. The synthesized catalyst is characterized by various spectroscopic techniques as XRD, FT-IR, BET surface area, TGA, SEM and TEM. The catalyst showed high thermal stability and also has good catalytic activity for the esterification of n-butanol and acetic acid.
