Controlling the shape of nanomaterials during synthesis involves manipulating various parameters, such as:
1. Chemical Precursors: The choice of chemicals can influence the nucleation and growth processes. 2. Temperature and Pressure: These conditions can affect the kinetic energy and mobility of atoms, thereby influencing shape. 3. Surfactants and Capping Agents: These molecules can bind to specific facets of a growing crystal, controlling its shape by inhibiting growth in certain directions. 4. Template Methods: Using pre-formed templates can guide the growth of nanomaterials into desired shapes.
