二氧化铅电极掺杂改性研究进展

Research Progress on Modification of PbO_2 Electrodes

概述了二氧化铅电极掺杂改性的研究进展。电沉积二氧化铅时,添加某些离子或颗粒能改善其电催化活性和稳定性,这些离子和颗粒主要包括Bi3+、F+、Fe3+、Co2+、Ni2+、Ce3+、RuO2、PAN、WC、TiO2和稀土元素等。展望了未来二氧化铅电极材料的发展趋势。

Research progress of lead dioxide electrodes modification was summarized in this paper. During electrodepositing pure lead dioxide, electrocatalytic activity and stability of the PbO2 electrodes could be considerably enhanced by adding some foreign ions or fine particles, such as Bi3＋ ,F＋ ,Fe3＋ ,Co2＋ , Ni2＋ ,Ce3＋ ,RuO2 ,PAN, WC,TiO2 and rare earth element, into the electrolyte. Also the developmental tendency of PbO2 electrodes was prospected.
