Pollen-like ZIF-8 colloidosomes via emulsion templating and etching†
Abstract
We report a one-pot emulsion-templating strategy for the preparation of ZIF-8 microcapsules both in the presence and absence of surfactants. Capsule diameter is tuneable in the range 1–10 μm, and they can be post-synthetically etched with excess imidazole to form hierarchical architectures resembling Oleaceae pollen grains.
