Synthesis mesoporous silica using oleic acid as template and 3-aminopropyltrimethoxysilane as co-structure directing agent has been conducted. As a silica source used tetraetylorthosilicate. The reaction was carried out under three conditions: first, reducing the concentration of tetraethylortosilicate and 3-aminopropyltrimethoxysilane and varying the volume of HCl 0.1M; second, increasing the concentration of tetraethylortosilicate and 3-aminopropyltrimethoxysilane by varying the addition of HCl 0.1M and the third was carried out with the addition of methanol but without the addition of HCl 0.1M. The obtained silica mesopores were characterized by infrared spectrometer, X-ray diffraction and adsorpsi-desorption isotherm and scanning electron microscopy.
