Several methods are employed to synthesize oxide nanoparticles:
- Sol-Gel Process: This method involves transitioning from a colloidal solution (sol) to a solid (gel) phase to produce oxide nanoparticles. - Hydrothermal Synthesis: This technique uses high temperature and pressure in aqueous solutions to produce oxide nanoparticles. - Chemical Vapor Deposition: Oxide films and nanoparticles are synthesized by reacting gaseous precursors on a substrate. - Mechanical Milling: Bulk materials are ground down to nanoscale particles using mechanical forces.
