Al-MCM-48: synthesis and adsorption properties for water, benzene, and nitrogen

Mesoporous aluminosilicate molecular sieves with the MCM-48 structure have been synthesised using the method of grafting aluminium onto the purely siliceous material. The products were characterised with XRD and adsorption techniques. The obtained materials exhibited high surface areas and high total pore volumes. Adsorption of nitrogen, benzene, and water on the materials with various contents of Al proceeded similarly despite different physicochemical. properties of the adsorptives as well as different adsorbent-adsorbate interactions.
