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 CO adsorption. This mesoporous silica with a larger pore volume was analyzed by TEM, FT-IR, low angle X-ray diffraction, N-adsorption analysis, and CO adsorption experiments in comparison with the mesoporous silica synthesized with the traditional calcination method.
尽管介孔二氧化硅材料已被广泛研究用于许多应用，但大多数二氧化硅材料是通过煅烧工艺制备的。我们成功开发了一种在室温下合成介孔材料的简便方法。虽然通过煅烧工艺和室温工艺这两种不同方法制备的二氧化硅材料具有相似的比表面积，但室温工艺制备的二氧化硅材料具有明显更大的孔体积。这种更大的孔体积有可能附着可应用于诸如CO吸附等各种工业领域的官能团。通过透射电子显微镜（TEM）、傅里叶变换红外光谱（FT-IR）、低角度X射线衍射、N吸附分析以及与传统煅烧方法合成的介孔二氧化硅相比的CO吸附实验，对这种具有更大孔体积的介孔二氧化硅进行了分析。
