Several methods are employed to synthesize noble metal nanocrystals, including: - Chemical Reduction: Using reducing agents to convert metal precursors into nanoparticles. - Electrodeposition: Applying an electric current to reduce metal ions onto a substrate. - Sol-Gel Method: Forming a colloidal suspension that is subsequently dried and calcined. - Seed-Mediated Growth: Using pre-formed seeds to direct the growth of nanocrystals into desired shapes.
