제목 솔-젤법에 의한 메조기공 알루미나, 실리카, 알루미나/실리카 복합 입자 합성 및 VOC 흡착 특성 분석
초록 Among various VOC removal methods, adsorption has been considered one of the most favorable method to control VOCs due to ease of application and high efficiency. In this work, various mesoporous metal-oxide granules (Al2O3, SiO2, and Al2O3/SiO2) were prepared by combining sol-gel method and spray pyrolysis technique. First, stable boehmite, and silica sols were prepared by sol-gel methods. Then, the sols were mixed with CTAB, nebulized and pyrolyzed in the tubular furnace, producing the metal oxide granules. The porosity of the product granules were controlled using the CTAB concentration. The product granules were characterized by FE-SEM, BET, XRD, and TGA. A toluene breakthrough test was carried out using a glass bed under atmospheric pressure.
