Efficient adsorbents of nanoporous aluminosilicate monoliths for organic dyes from aqueous solution

► A feasible control over engineering of adsorbents with cage cubic Im3m mesopores was achieved. ► The mesocage adsorbents can act as a powerful tool for adsorption/removal of organic dyes. ► The adsorbents are reversible and offering potential for multiple adsorption assays.
