Controlled synthesis of different morphologies of BaWO4 crystals through biomembrane/organic-addition supramolecule templates

By the employment of supramolecule templates composed of biomembrane and organic reagents, control over the morphologies and sizes of BaWO4 crystals has been successfully achieved, and a series of flower-like, sphere-like, fasciculus-like, and other morphologies of BaWO4 were obtained at room temperature. Most of the morphologies are reported for the first time. Furthermore, the control rule of supramolecule templates was also discussed. This method may satisfy the requirements of materials of various morphologies and sizes by using different supramolecule templates, and provide significant theoretical reference to the controlled synthesis of other crystals.
