Abstract

The invention discloses a preparation method of a neodymium-doped lead dioxide electrode. The preparation method comprises the following steps: performing polishing and etching pretreatment on a titanium substrate and then coating the surface of the titanium substrate with a tin-antimony middle layer by use of a pyrolytic process, and furthermore, and electroplating a neodymium oxide-containing beta-PbO2 crystal active layer by use of an electrodeposition method, thereby forming the neodymium-doped lead dioxide electrode. According to the preparation method of the neodymium-doped lead dioxide electrode, the surface structure of the electrode is improved by virtue of the doping of neodymium, the catalytic oxidizing activity and the stability of the electrode are improved, and the prepared electrode is capable of effectively degrading organic matters, good in treatment effect, high in current efficiency and low in cost, and has an excellent application value.

Description

Technical field

[0001] The invention belongs to the field of environmental wastewater treatment, and specifically relates to a method for preparing a neodymium-doped lead dioxide electrode. Background technique

[0002] Electrochemical water treatment technology is widely used in the treatment of refractory organics because of its advantages of no or little consumption of chemical reagents, no secondary pollution, easy operation, and ability to mineralize almost all organics in the treatment of organic wastewater. In the electrochemical reactor, the electrode is at the core. The high reaction rate and good selectivity exhibited by electrode materials when degrading organic matter are important indicators for evaluating their electrocatalytic properties.

[0003] The Dimensionally Stable Anode (DSA) uses titanium and other metals with good corrosion resistance as the substrate, and the substrate material is coated with a catalytic coating and modified by element doping to improve t...
