Several synthesis methods are used to produce ZnO nanowires, each with its advantages and limitations:
- Chemical Vapor Deposition (CVD): This method involves the chemical reaction of zinc and oxygen precursors in a high-temperature furnace to grow nanowires on a substrate. It allows for precise control over nanowire dimensions and morphology. - Hydrothermal Synthesis: This low-temperature method involves the reaction of zinc salts with alkaline solutions in an autoclave. It is cost-effective and scalable, making it suitable for large-scale production. - Sol-Gel Techniques: Involves the hydrolysis and condensation of zinc alkoxides or acetates in a solution, followed by thermal treatment to form nanowires. It offers simplicity and ease of doping with other elements.
