AbstractA comparative study of chemical and textural properties for materials obtained by three different methods of dealumination of alumina-rich parent Ca-A zeolite showed that the method using ammonium hexafluorosilicate (AFS) resulted in the most interesting developments of mesoporous materials, with much higher void volumes and cation exchange properties than obtained by acid leaching or hydrothermal treatment. AFS treatment on both the Na and Ca forms of zeolite A resulted in materials with 12 nm sized mesopores, whereas smaller mesopores of about 4 nm were obtained when using the higher Si/Al ratio parent zeolite Na-X. Pore size distribution profiles obtained for these new materials are fairly narrow, indicating homogeneous mesopore sized solids.

<p>In the present paper, a comparative study on the synthesis of metal organic framework-199 by microwave and solvolthermal method was demonstrated.<strong> </strong>The obtained materials were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), nitrogen adsorption/desorption isotherms and thermal gravity (TG). The microwave synthesis of MOF-199 has been compared to its conventional hydrothermal synthesis. It is found that by using microwave synthesis MOF-199 can be obtained in a much shorter synthesis time with improved yield and textural properties. It is supposed that the microwave energy emitted fast and uniformly, creating nuclei through the solution which quickly grew to crystals and both the nucleation and crystallization steps were accelerated. These make the microwave synthesis advantages over solvolthermal synthesis.<strong></strong></p>
