The electrochemical activity of a high surface area furnace black, Black Pearls 2000 and an acetylene black, Shawinigan Black, were studied in 25% KOH at temperatures from 45/sup 0/C to -15/sup 0/C. A relationship was found between the graphitic character of the carbons and their activities for oxygen formation and surface oxide formation, the furnace black being more active for surface oxide formation and the acetylene black being more active for oxygen generation. The carbons behaved similarly in the cathodic region, exhibiting two distinct peaks apparently related to the reduction of oxygen or of surface oxides.
