Ordered mesoporous silica materials are known for their high surface area and highly ordered structure. One of the main advantages of the synthesis of ordered mesoporous silica by soft-templating with amphiphilic molecules is the ability to tailor the mesostructure by using micellar swelling agents. In this context, the addition of hexane and polypropylene glycol (PPG) as micellar swelling agents in the facile room-temperature synthesis of COK-12 was studied to tailor the mesoporous structure of the system. Hexane was used as a micelle expander and as an agent to produce silica mesocellular foams (MCF), resulting in a material with “ink-bottle” pores with a larger diameter than that of the original COK-12, with up to 8.5 nm in cell diameter and 5.3 nm in window diameter. By adding PPG into the synthesis, a shift of the mesostructure of COK-12 from 2D hexagonal to a multilamellar vesicular (MLV) configuration was observed, resulting in the progressive formation of this type of material with increasing concentration of PPG.

有序的介孔二氧化硅材料以其高表面积和高度有序的结构而闻名。通过两亲性分子的软模板合成有序介孔二氧化硅的主要优点之一是能够通过使用胶束膨胀剂来调整介孔结构。在这种情况下，研究了在方便的室温合成COK-12中添加己烷和聚丙二醇（PPG）作为胶束膨胀剂，以调整系统的介孔结构。己烷用作胶束膨胀剂和生产二氧化硅中孔泡沫（MCF）的试剂，产生的材料具有“墨水瓶”孔，其直径大于原始COK-12的直径，最大可吸收8.5 nm。单元直径和窗口直径5.3 nm。通过将PPG添加到合成中，
