| 摘 要： | 针对直接甲醇燃料电池阴极常用的铂基催化剂易中毒、选择性差等问题,以Fe2＋为模板剂控制合成了酞菁铁配合物催化剂.红外光谱测试表明,Fe2＋与酞菁中的N形成了配键.研究结果表明,随着温度的升高,酞菁铁对氧还原反应的电催化活性逐渐增强,且对甲醇氧化反应无催化活性,证明酞菁铁具有较好的催化选择性.

| Abstract: | This paper is focused on the issues of platinum-based cathode for direct methanol fuel cell,such as high sensitivity to catalyst poisons and poor selectivity against methanol oxidation.Phthalocyanine iron complex catalyst with controlled morphology was synthesized using Fe2+ as the template agent.IR spectra testing showed that N in phthalocyanine molecule coordinated with Fe2+.According to the electrode polarization curves,the electro-catalytic activity of phthalocyanine iron for the oxygen reduction was gradually improved with the rise of the temperature.And the catalyst displayed inertness for methanol oxidation.It is proved that phthalocyanine iron has good catalytic selectivity. |
