Abstract:

Recently, microporous materials,displaying zeolite-type properties, have attracted much interest^[1]. As one of the most interesting synthetic molecular sieves^[2],the porosity of porous clays plays a very important role on the application of microporous materials. Here we investigate the adsorption behavior and the pore size distributions of several porous clays materials by using N₂ adsorption at low temperature (77 K),and discuss the influences of different crosslinking agents on resulting porosity of porous clays.
