| 摘 要： | 比较了甲醇对Pt/C和炭载四羧基酞菁钴(CoPcTc/C)催化氧还原性能的影响.结果表明,甲醇使Pt/C催化氧还原的性能严重降低,而对经800℃热处理的CoPcTc/C(CoPcTc/C-800)基本没有影响;并且CoPcTc/C-800催化氧还原的性能优于经其它温度热处理的CoPcTc/C,CoPcTc/C-800是一种较好的直接甲醇燃料电池的耐甲醇阴极电催化剂.XPS结果表明,CoPcTc/C-800的活性位可能是含CoN4结构的物质和零价Co的混合物.

| Abstract: | The electrocatalytic performance of Pt/C and cobalt tetracarboxylic phthalocyanine supported on carbon black(CoPcTc/C) for oxygen reduction were compared. The results showed that the presence of methanol reduced seriously the electrocatalytic activities of Pt/C for the oxygen reduction, while it had no effect on that of heat-treated CoPcTc/C at 800 ℃(CoPcTc/C-800). And the electrocatalytic activity of CoPcTc/C-800 for the oxygen reduction was higher than those heat-treated at other temperatures. Therefore, CoPcTc/C-800 was a promising candidate of methanol-tolerant cathode electrocatalyst in DMFC. XPS result reveals that active site of CoPcTc/C-800 may be the composite of CoN4 and Co0. |
