In the present research, the SBA-15 mesoporous silica synthesis using TEOS and rice husk ash (RHA) as the silica sources and Pluronic P123 as the template under different acidic conditions in short ripening time were studid. The high quality sample was obtained from TEOS and 1 molar HCl, while high quality RS-3M sample was obtained by 3 molar HCl with RHA used as silica source. The effect of acid concentration on the texture and morphology of obtained SBA-15 samples were investigated by small angle XRD and SEM techniques.
