Abstract:

Mg-Al hydrotalcites with different Mg/Al ratios and their polyoxometalate intercalates were synthesized by direct ion-exchange reactions. The porous structures of the pillared products were studied by adsorbing various molecules with different, kinetic diameter on them. The results show that the porous structures of the pillared products can be adjusted either by changing the layer charge densities or by changing the pillar densities, i. e. the pore diameter will increase with the increament of the Mg atoms in the layers and the polyoxometalate charges in the gallery.

Key words: Mg/Al atomic ratio, Polyoxometalates, Pillared hydrotalcites, Synthesis, Adsorption properties
