Hydrothermal Synthesis

A method for synthesizing materials, particularly nanoparticles, nanorods, and other nanostructures
Uses a high-temperature aqueous solution
Involves dissolving precursors in water or an aqueous solution, heating it in a sealed vessel (autoclave) above water's boiling point, maintaining this temperature and pressure for a specified time, and then cooling the solution to allow the material to precipitate or form.

Advantages

Relatively low cost and simplicity
Ability to produce high-quality materials with controlled size and shape
Flexibility in choosing precursors and reaction conditions
Environmentally friendly as it uses water as a solvent.

Applications

Nanoparticle synthesis (e.g., metal oxides, quantum dots)
Nanorod synthesis (e.g., metal oxides, semiconductors)
Nanostructured materials (e.g., zeolites, metal-organic frameworks)
Biomaterial synthesis (e.g., hydroxyapatite, calcium carbonate)
Energy storage material synthesis (e.g., battery electrodes)
Catalytic material synthesis

Factors Influencing Hydrothermal Synthesis
