High internal phase emulsions (HIPEs) as template for fabrication of porous materials has attracted much attention, due to the high porosity and tunable porous structure. But the enormous consumption of organic solvents is still a nightmare for the practical application. In comparison, the aqueous foam without need any organic solvent and hence has greater advantages in the porous materials preparation. In this study, a novel Pickering foam which was stabilized by modified sepiolite (Sep) was prepared and applied as the template for preparation of the porous material via thermal-initiated polymerization. The Pickering foam had excellent ability and stability in the pH of 4–11 and the obtained porous adsorbent possess sufficient and tuned pore structure. The porous materials as adsorbent has favorable performance for adsorption and selective removal of cationic dyes, and the understanding adsorption capacities for Methylene blue (MB) and Methyl green (MG) can be achieved with 1421.18 mg/g and 638.81 mg/g within 60 and 45 min at 25 °C, respectively. This porous material can be as the potential adsorbent for adsorption or separation of organic pollutants.

由于高孔隙率和可调节的多孔结构，作为制备多孔材料的模板的高内相乳液（HIPE）备受关注。但是有机溶剂的大量消耗对于实际应用仍然是一场噩梦。相比之下，水性泡沫不需要任何有机溶剂，因此在多孔材料制备中具有更大的优势。在这项研究中，制备了一种新型的由改性海泡石（Sep）稳定的Pickering泡沫，并将其用作模板，用于通过热引发聚合。Pickering泡沫在4-11的pH值下具有出色的能力和稳定性，所获得的多孔吸附剂具有足够且可调节的孔结构。多孔材料作为吸附剂对阳离子染料的吸附和选择性去除具有良好的性能，对于亚甲基蓝（MB）和甲基绿（MG）的理解吸附容量可以在60和60以内达到1421.18 mg / g和638.81 mg / g。分别在25°C下45分钟。该多孔材料可以作为潜在的吸附剂来吸附或分离有机污染物。
