Abstract

Silica material synthesis has been carried out using tetraethylortosilicate (TEOS) as a source of silica, methyl ester oleate as a template, 3-aminopropyltrimethoxysilane as a co-structure directing agent (CSDA), and deionized water as the solvent. The synthesis of silica material was made by varying the mass of methyl ester oleate, namely 3.7358 g, 4.2695 g, 4.8032 g, 5.3369 g, and 5.8706 g. The TEOS and APMS mixture was added to a mixture of methyl ester oleate, 0.1 M HCl, and deionized water and then stirred at room temperature for 2 hours. The mixture was then cooked in an oven at 80ο C for 72 hours. Separation of the product is done by centrifugation, The resulting solid is dried and then calcined at 550ο C for 6 hours. The XRD analysis results of the product showed diffraction peaks which widened at 12ο to 30 ο which indicated that the resulting material was amorphous. The FT-IR spectrum shows the presence of Si-OH and Si-O-Si groups which are characteristic of silica material. SEM analysis shows the existence of hollow particles with non-uniform size. Nitrogen isotherm (BET) adsorption shows type IV isotherm curves and H1 type hysteresis loops with uniform pore sizes on the variation of methyl oleate 4.8032 g, which is 2.28 nm. This identified that the optimum conditions for the synthesis of silica mesoporous material with the methyl ester oleate template had been achieved.
