The purpose of this study was synthesizing mesoporous silica SBA-15 and investigated the effect of the initial
temperature of the preparation surfactant using the hydrothermal process to synthesize silica SBA-15. Pluronic
(P123) as surfactant template and TEOS as material precursor acted as a building block of the mesoporous silica
material. Therefore, the interaction surfactant template and precursor during the hydrothermal process guided to
silica SBA-15 properties. The results suggested that the physicochemical properties of these materials did not
change significantly, but different condition temperature of surfactant and hydrothermal process affected the size of
the specific surface area, pore volume, and pore size distribution. The largest specific surface area was 560 m2g-1, pore volume was 1.57 m3 g-1 and ordered pore size distribution around 11.24 nm after the initial temperature of the surfactant at 15oC and hydrothermal process at 100oC for 48 h. This resulted properties of SBA-15 are potentially
applicable in various chemical and non-chemical based industries
