英文摘要A cobalt hydroxide modified glassy carbon (Co(OH)(2)/GC) electrode has been fabricated by a galvanostatic electrodeposition method. The catalytic activity for the oxygen (O(2)) reduction reaction (ORR) of this electrode in alkaline media is studied by cyclic voltammetry, rotating disk electrode voltammetry, and rotating ring-disk electrode voltammetry. The O(2) reduction at the Co(OH)2/GC disk electrode has been found to undergo an electrochemical process followed by sequential disproportionation of the electrochemical reduction intermediates, i.e.. superoxide anion (O(2)(center dot-)) and hydrogen peroxide anion (HO(2)(-)) in 0.1 M KOH solution. The Co(OH)2 is first found to possess an excellent catalytic activity not only for the disproportionation of the O(2)(center dot-) produced into O(2) and HO(2)(-) but also for that of the HO(2)(-) produced, combined with electrochemical reduction of O(2) mediated by surface functional groups at the carbon electrode surface. The Co(OH)(2) is a potential electrode material for the ORR in alkaline fuel cells and metal-air batteries. (C) 2009 Elsevier B.V. All rights reserved.
