The impact of different temperatures on Nano Silver Carbon manufacturing by Arc Discharge method

Abstract

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.
