In this work, we propose a method for synthesizing silver nanoparticles (Ag NPs) utilizing a sonication-assisted electrochemical approach with a common ultrasonic cleaner. Silver nitrate is employed as the precursor and polyvinylpyrrolidone functions as the ligand. The incorporation of sonication is identified as crucial for achieving several benefits such as enhanced mass transfer, improved dispersion of reactants, and the prevention of electrode fouling. Optimized sonication and electrochemical conditions synergistically contribute to a higher yield of well-dispersed Ag NPs, which are characterized by an average size of 10 nm. Furthermore, the electrode's suitability for the continuous synthesis of Ag NPs over an extended period is highlighted owing to effective electrode surface cleaning facilitated by sonication. This cleaning process proves to be essential in maintaining the electrochemical activity of the electrode, ensuring consistency in the synthesis process. The proposed sonication-assisted electrochemical synthesis method not only addresses challenges associated with electrode fouling but also significantly enhances the dispersity and yield of the resulting particles, making it valuable for scalability and practical applications in various fields, including sensors, catalysis, and nanotechnology.
