Abstract

(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.
