SAPO-56 crystals were synthesized via microwave heating. The resultant crystals displayed high catalytic activity in the synthesis of chloropropene carbonate from CO2 and epichlorohydrin. The enhanced catalytic activity of SAPO-56 crystals was related to their high CO2 adsorption capacity, small crystal size, and the presence of acid sites.

an account is presented on investigation of the effects of synthesis parameters, i.e., reaction sources, silica to alumina ratio, acid molar ratio and crystallization conditions on the crystallinity, morphology and particle size of sapo-34. the synthesis conditions were designed to produce small particles with narrow size range. the prepared samples were characterized by xrd and sem techniques ...

Fabrication of hierarchical porosity in microporous zeolites is a key to overcoming the inherent mass-transfer limitation and improving molecular accessibility active sites. The present study reports facile cost-effective etching strategy based on crystal metastability construct SAPO-34 (CHA-type) zeolite. with high crystallinity obtained conveniently via an extended hydrothermal treatment with...
