The mesoporous silica material SBA-15 was characterized by N 2 adsorption/desorption Analysis, Small Angle X-Ray Diffraction (SAXRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR). SBA-15 material resulted from the calcination method for template removal has a surface of 876 m 2 /g, a pore volume of 5,1 cm 3 /g and a pore diameter of 1,13 nm. The SAXRD pattern of SBA-15 showed three distinctive peaks with Miller indeces of 100, 110 and 200 respectively. The morphology of the SBA-15 material has the form of aggregate particles with a reguler cylindrical structure on the particles. Infrared spectra of SBA-15 showed the presence of functional groups, namely Si-O-Si, Si-OH and –OH.   Key w ords : Mesoporous silica, SBA-15, sonication %U http://jurnal.kimia.fmipa.unmul.ac.id/index.php/prosiding/article/view/1184 %J PROSIDING SEMINAR NASIONAL KIMIA %0 Journal Article %P 193-198%V 1 %N 1 %8 2023-07-12
