Anionic surfactants as nanotools for the alignment of non-spherical zeolite nanocrystals
Zeolite microspherulites are produced upon sonication of non-spherical zeolite nanocrystals in water-in-oil emulsions. The zeolite nanocrystals in the outermost two layers of the microspherulites align with high ordering upon the addition of anionic surfactants. Highly perforated microspherulites are obtained by shorter sonication times. The Figure shows a zeolite-X spherulite and surface details.
