Porous silica exhibiting a hierarchically ordered trimodal pore system with a well-defined reverse opal microstructure and bimodal mesoporosity in the walls has been prepared by using polystyrene latex spheres, a novel block copolymer and an ionic liquid surfactant as templates. The resulting materials exhibit hierarchical order at three length scales (small mesopores: 2-3 nm; large mesopores: 11-12 nm; macropores: 360 nm).
通过使用聚苯乙烯胶乳球、一种新型嵌段共聚物和一种离子液体表面活性剂作为模板，制备出了具有分级有序的三峰孔系统的多孔二氧化硅，其具有明确的反蛋白石微观结构且孔壁中具有双峰介孔性。所得材料在三个长度尺度上呈现出分级有序（小介孔：2 - 3纳米；大介孔：11 - 12纳米；大孔：360纳米）。
