摘要
The Ag NPs were produced by sonicat the electrochemical cell that the titanium horn serves as cathode and the anode was high purity silver foil, while the electrolyte in all experiments was (0.2 g Ag in 250 ml deionized water), the pH was varied between 2 to 8 using sulfuric acid and sodium bicarbonate diluted solutions, the current density was maintained at 5mA/cm. The quality of the products was extensively examined using: SEM, TEM, AFM, XRD, UV-visible and EDX techniques. The results reflected a clear fact that the more acidic electrolyte (lower pH value) has produced distorted spherical larger AgNPs, with a narrow particles size distribution, while decreasing the acidity (higher pH value) led to smaller particle size, and wider size distribution spectrum.
