Silver nanoparticles (AgPNs) were prepared by high-voltage electrochemical methods using silver anode to produce silver ions and hydrogen gas at the cathode from electrolysis of distilled water as solvents. The electrolyte solution resulting from the obtained AgPNs product does not contain ions of the electrolyte solution such as conventional chemical or electrochemical methods. Silver anode dissolution process would provide Ag+ and disperse it into distilled water. | Electrochemical preparation of nano silver by combining high DC voltage with anodic plasma
