The influences of methanol on the performances of Pt/C and CoPcTc(cobalt of tetracarboxyl phthalocyanine)/C heat-treated at 800 ℃ for oxygen reduction reaction(ORR) were studied and compared. The results showed that for Pt/C electrocatalyst methanol oxidation and ORR occurred with no apparent interaction above 0.64 V and below 0.18 V vs SCE. But in the range of 0.18 to 0.64 V, methanol adversely affects the performance of Pt/C for ORR. The methanol had no effect on the performance of CoPcTc/C heat-treated at 800 ℃ for ORR. Thus CoPcTc/C heat-treated at 800 ℃ is a promising catalyst for ORR with higher activity and good methanol-tolerant ability.

Keywords: Pt/C   CoPcTc(cobalt of tetracarboxyl phthalocyanine)/C   Oxygen reduction   Electrocatalyst   Methanol-tolerant
