Abstract

Although mesoporous silica materials have been widely investigated for many applications, most silica materials are made by calcination processes. We successfully developed a convenient method to synthesize mesoporous materials at room temperature. Although the silica materials made by the two different methods, which are the calcination process and the room-temperature process, have similar specific surface areas, the silica materials produced with the room-temperature process have a significantly larger pore volume. This larger pore volume has the potential to attach to functional groups that can be applied to various industrial fields such as CO₂ adsorption. This mesoporous silica with a larger pore volume was analyzed by TEM, FT-IR, low angle X-ray diffraction, N₂-adsorption analysis, and CO₂ adsorption experiments in comparison with the mesoporous silica synthesized with the traditional calcination method.

Keywords: mesoporous silica; room-temperature synthesis; CO₂ adsorption; high pore volume
