Abstract

Synthesis of various sizes particulate Ag supported on carbon nanocapsules (CNCs) were conducted in typical impregnation and wet chemical approach for physical characterization and electrochemical analysis in alkaline electrolyte. XRD of the assynthesized powders indicated Ag in FCC phase. In i-V polarizations, the nano Ag/CNCs derived wet chemical route exhibited much enhanced oxygen reduction reaction capabilities than those of Ag/CNCs from impregnation method. Similar behaviors were recorded in galvanostatic discharging measurements between 10 and 200 mA/cm2.
