Synthesis of Hierarchical Superstructures Consisting of BaCrO₄ Nanobelts in Catanionic Reverse Micelles

Abstract

A variety of novel BaCrO 4 nanostructures , such as nanobelts and their tree‐like superstructures (see Figure), have been synthesized in a unique catanionic reverse micelle system by simply changing the mixing ratio between the anionic and cationic surfactants. This synthetic method provides a simple, novel method for direct assembly of inorganic nanobelts into hierarchical superstructures.
