| dc.description.abstract |
Mesoporous Al2O3 were positively synthesized via treatment of the freshly precipitated amorphous alumina gel using aluminium sulphate as aluminium source, and sodium dodecyl sulphate (SDS) as structure-directing agent (SDAs). The microstructures, morphologies and textural properties of the as-prepared materials were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and thermo gravimetric analysis (TG-DTA). The calcined product at 600 degrees C was highly porous in nature having a BET surface area of 42m(2)/g. These porous Al2O3 exhibits excellent adsorption performance for Congo red and the corresponding decolourisation efficiencies reached 99% in just 15 min at 27 degrees C. The subsequent calcined product at 1200 degrees C is the alpha alumina single crystal hexagonal platelets with rhombohedral crystallization. |
