In the past decades mesoporous materials, which have uniform pore size distribution, high surface area and large pore volume, have attracted much attention for their potential applications including catalysis, sensor, medicine and adsorption. Among various mesoporous materials, mesoporous alumina showed advantageous acidic property and great stability in harsh condition, resulting in excellent performance in the catalytic reforming, toxic chemical adsorption. In this study, we prepared spherical mesoporous alumina through sol-gel chemistry derived synthesis followed by heat treatment. We controlled physical properties of spherical mesoporous alumina particle including pore diameter and particle size. The prepared mesoporous alumina particles are characterized by N2 adsorption, transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Temperature programed desorption analysis. When used as an adsorbent for removal of toxic gas molecules, the spherical mesoporous alumina showed considerable performance under ambient condition. In this presentation, we will discuss further our synthesis, characterization, adsorption performance of Spherical Mesoporous Alumina.
