Abstract

The invention discloses an electrochemical industrial titanium anode with oxide seed layer, which is characterized by the following: depositing to cover oxide seed layer on the titanium base of titanium anode; coating subsequent coating layer on the exterior layer of oxide seed layer.

Description

technical field [0001] The invention relates to an electrode material mainly used in the field of electrochemical industry, in particular to an electrochemical industrial titanium anode with an oxide seed layer. Background technique [0002] The electrode material used in the early days of electrochemistry was artificial graphite. After the advent of noble metal oxide electrodes in 1967, graphite electrodes were gradually replaced by them. The earliest successful formulation of noble metal oxide electrodes is the Ru-Ti oxide-coated titanium anode. In order to obtain electrode materials with high activity and high corrosion resistance, scientists have proposed electrochemical titanium anodes with seed layers [Shao Yanqun et al., "Titanium Anodes for Electrochemical Industry with Seed Layers", 031158463]. For the titanium anode with a fine seed layer, the seed is deposited on the titanium substrate, the seed is a nanoscale noble metal or noble metal compound, and the seed la...
