阳极PbO_2膜电催化性能的研究

Study of Anodic PbO_2 Film Electrocatalytic Properties

过实验探讨了铅（Ｐｂ）在阳极极化过程中形成的阳极ＰｂＯ＿２膜的电催化性能，结果表明：在硫酸溶液中的恒电位极化得到铅的阳极Ｐｂ０＿２膜，比未形成阳极膜的铅电极（Ｐｂ）对于Ｍｎ￣（２＋）氧化成的反应具有电催化性能，能使反应速率加快。

The electrocatalytic property of PbO_2 film formed from lead(pb)during anodic polarizationis experimentally studied.The result shows that the PbO_2auodic film formed by the constant vollngepolarization brings a stroiiger catalytic ftinction to the oxygenation from Mn￣(2+) ,to MnO_4 than the leadelecto de(pb),thus increasing the reaction speed.
