Aluminosilicate mesoporous materials were synthesized using F108 template (polyethylene glycol-polypropylene glycol-polyethylene glycol) at a concentration of 0.034 g/ml and the molar ratio of Al₂O₃ to SiO₂ was 0.09. The products were then characterized using nitrogen adsorption/desorption tests, scanning electron microscopy (SEM), and X-ray diffraction (XRD). The effects of various crystallization temperatures as well as sodium hydroxide concentrations on the average diameter, pore volume, surface area, and morphology of the synthetic material were analyzed. Results showed that a sodium hydroxide concentration of 11 mol/L and a crystallization temperature of 130 °C produced a synthetic material with regular pore size and homogeneous arrangement including a specific surface area of 137.62 m²/g, an average pore volume of 0.27 cm³/g, along with an average pore size of 15.33 nm.
