초록
A mesoporous silica SBA-15 was prepared by self-assembling pathway using surfactant as the template in silicate solution extracted from mine tailings. The synthesized mesoporous silica SBA-15 from the mine tailings and TEOS were characterized by small angle X-ray diffraction (SAXA), scanning electron microscope (SEM), high-resolution transmission electron microscopy (HRTEM) and nitrogen physisorption. The as- synthesized mesoporous silica SBA-15 (SBA-15-MTs) from the mine tailings had high surface area of 513 m^2/g and the average pore size of 6.20 nm with a well-ordered hexagonal structure. Therefore, it is feasible to synthesize mesoporous silica SBA-15 materials using the mine tailings as silica source.
