The graphite electrode surface onto which Cobalt(II) 1,2,3,4,8,9,10,11,15,16,17,18,22,23,24,25-hexadecafluoro-29H,31H-phthalocyanine (CoPcF16; CoIIHFPC)is adsorbed displays a strong electrocatalytic activity toward O2 reduction. CoIIHFPC instead of CoPc(NH2)4, as the catalyst for electrochemical reduction of O2 because CoPcF16 contains electro-withdrawing groups, and thus, has a higher catalytic activity and is more stable for O2 reduction compared with CoPc(NH2)4. The OH- concentration has a very strong effect on the reduction process. Higher OH- concentration could stabilize O-2 ion[1-3].
