采用浓缩硅酸盐和表面活性剂前驱体溶液快速凝胶化的自组织工艺制备了具有介孔壁的大通道二氧化硅膜。由直径约1 μm的直大通道组成的特定分层多孔框架类似于硅藻的生物硅结构。我们将模拟硅藻通道介孔二氧化硅膜应用于高渗透率过滤和增强光催化系统。大通道的存在提高了介孔二氧化硅膜的过滤性能和作为光催化剂载体的性能。
Silica membranes having macrochannels with mesoporous walls were spontaneously fabricated using a self-organized process with rapid gelation of concentrated silicate and surfactant precursor solutions. The specific hierarchical porous framework consisting of straight macrochannels ca. 1 μm in diameter is similar to that of a biological silica frustule of diatoms. We applied the diatom-mimetic channeled mesoporous silica membranes to high-permeability-rate filtration and enhanced photocatalytic systems. The presence of macrochannels was found to improve the performance of the mesoporous silica membranes in filtration and as a photocatalyst carrier.
