The arc discharge process was adjusted by varying the temperature by two values The temperature, applied voltage, electrode shape, and kind of dielectric medium all have a significant impact on the mass production, stability, yield, and size and form. AgNPs-CNT with an average particle size of 13 nm was produced by the system (A) at a temperature of -10° C, but in system (B) the temperature was about 55° C and the production was spherical AgNPs/C with an average particle size of 30 nm. In both systems, the two electrodes were 99.9% pure silver as the anode with a diameter of 0.5 cm and 10 cm of length and carbon as the cathode with a diameter of 0.2 cm and 4 cm of length, the applied voltage was 30 A and the dielectric medium was ethanol. 1Energy-dispersive X-ray spectroscopy (EDX), Transmission Electron Microscope (TEM), and ultraviolet-visible spectrophotometer (UV-Vis) were used to characterize the yields. Every characterization demonstrates that the production of nanoparticles for both systems was successful.
