Charged Inorganic Nanowire‐Directed Mineralization of Amorphous Calcium Carbonate

Charged inorganic nanowires (e.g., tellurium nanowires, TeNWs), analogous to supramolecular templates, have been used to direct the mineralization of uniform amorphous calcium carbonate (ACC) shells on their surfaces. The role of surface charges of TeNWs, mixed solvent ratio, and the diameter of the TeNWs is discussed, and the formation mechanism of ACC-coated tellurium nanowires (ACC@TeNWs) is elucidated. This charged-nanowire-directed mineralization process represents a new approach that could be extended for the synthesis of other amorphous inorganic nanostructures in the future.
