（如图所示） Shipshape：通过使用弱酸催化剂实现反蛋白石二氧化硅骨架的分解，在胶体晶体模板内合成具有可控双峰尺寸分布的介孔二氧化硅纳米立方体和球体。成形的纳米颗粒可以通过纳米铸造来复制以获得具有相似形态的碳或聚合物纳米颗粒。
(Figure Presented) Shipshape: Mesoporous silica nanocubes and spheroids with controllable bimodal size distributions were synthesized within a colloidal crystal template by using a weak acid catalyst to effect the disassembly of an inverse opal silica skeleton. The shaped nanoparticles could be replicated by nanocasting to obtain carbon or polymer nanoparticles with similar morphologies.
