Mesoporous NaX zeolites (Meso-NaXs) have been successfully synthesized by a combination of preformed FAU (Faujasite) zeolite precursors and organic templates of cationic polymer (polydiallyldimethylammonium chloride, PDADMAC) and spirulina (SP). Characterization of Meso-NaXs by scanning electron micrographs (SEMs) indicates the existence of mesopores with sizes of 4–50nm. Furthermore, nitrogen adsorption–desorption...
