| 摘 要： | 文章比较了XC-72活性碳载Ir（Ir/C）、载Au（Au/C）和载Pt（Pt/C）催化剂对氧还原的电催化性能和抗甲酸能力,发现Ir/C催化剂对氧还原的电催化性能要差于Pt/C催化剂,但Pt/C催化剂的抗甲酸能力很差.Ir/C和Au/C催化剂都有很好的抗甲酸的能力,但Ir/C催化剂对氧还原的电催化性能要远好于Au/C催化剂.因此I,r/C催化剂适用于作直接甲酸燃料电池（DFAFC）中的阴极催化剂.

| Abstract: | The electrocatalytic performance for the oxygen reduction and formic acid tolerance ability of the Ir/C,Au/C and Pt/C catalysts were compared.It was found that the electrocatalytic performance for the oxygen reduction of the Ir/C catalyst was worse than that of the Pt/C catalyst.However,the formic acid tolerance ability of the Pt/C catalyst was very bad.Both Ir/C and Au/C catalysts possessed good formic acid tolerance ability,but the electrocatalytic performance for the oxygen reduction of the Ir/C catalyst... |
