Abstract

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 m2/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.

메조포러스 실리카 SBA-15는 광미로부터 추출된 실리케이트 용액을 이용하여 계면활성제 주형에 의한 자기조립과정으로 합성하였다. 광미와 TEOS로 각각 합성한 메조포러스 실리카 SBA-15의 기공구조는 X-ray 회절분석, 전자주사현미경(SEM), 투과주사현미경(TEM) 그리고 질소 흡착을 이용하여 평가하였다. 광미로부터 합성된 메조포러스 실리카 SBA-15(SBA-15-MTs) 513 m2/g의 높은 비표면적과 6.20 nm의 평균 기공 크기의 hexagonal 기공구조를 갖는 것으로 나타났다. 따라서, 본 연구결과 광미를 SBA-15와 같은 나노세공물질 제조시 실리카 공급원으로 활용할 수 있음을 알 수 있었다.
