What Parameters Affect the Synthesis of Gold Nanoparticles?
Several parameters impact the synthesis of gold nanoparticles via the Turkevich method: - Concentration of Sodium Citrate: Higher concentrations of sodium citrate lead to smaller nanoparticles due to increased nucleation rates. - Temperature: Higher temperatures accelerate the reduction process, leading to nanoparticles with different sizes and shapes. - Reaction Time: Prolonged reaction times can result in larger nanoparticles due to continued growth and aggregation. - pH of the Solution: The pH can influence the reduction rate and the stability of the nanoparticles.
