Table 1: Synthesis conditions, structural and textural parameters of cubic Fm3m aluminosilica membrane adsorbents fabricated using microemulsion phases of Brij 97 as soft templates with a wide range of Si/Al mole ratios. Unit lattice constant (aFm3m= d111√3), BET surface area (SBET), and NLDFT pore size distribution (PSD), and pore volume (Vp) are indicated.
