Abstract

Cellular and honeycomb structures of inorganic materials are of interest for applications requiring, e.g., catalyst supports or heat-resistant membranes. The synthesis fo cellular films from solvent-extracted metal-ion-containing microemulsions (the Figure shows a resulting hollow spherical shell of calcium carbonate) is extended here to FeIII, MnIII/IV, and CoIII oxides. The preparation is detailed and the mechanism of formation discussed.
