The Effect of Co-Surfactant Charge on the Structure Properties of Prepared Nano SBA-15 Using Sodium Silicate

Mesoporous SBA-15 with nono particle size distribution, different texture properties, and morphologies have been synthesized by controlling the hydrophilic-hydrophobic character during preparation, i.e., the solubility of micelles of pluronic P123 by controlling the charge of PEO hydrophilic-inorganic silica zone using different charge surfactants CTAB (cationic), F68 (nonionic), and SDBS (anionic). Sodium silicate was used as a silica source. Eo20Po70Eo20 co-polymer was used as a template at highly acidic conditions (pH<2). The experiments were characterized using XRD, FTIR, AFM, BET, and FESEM. The XRD and FTIR tests indicated that the SBA-15 is amorphous and free from impurities. The degree of particle dispersion is sequenced according to the order CTAB> SBDS> F68> bare p123. Also, the texture properties were between (577-900) m2/g surface area, (0.28-0.47) cm3/g pore volume and (1.98-2.3) nm pore size. The optimum texture properties were achieved using CTAB co-surfactant.
