What kinds of coatings are available for titanium electrodes? Which are oxygen evolution anodes? Which are chlorine-eluting anodes?

Titanium electrode is an anode coated with electrocatalytic oxidation coating on the basis of titanium substrate through special and multiple processes. His scientific name is DSA anode, which belongs to a kind of insoluble anode. In China, the more commonly used name is titanium composite oxide (mmo) coating, or mmo titanium anode.

Titanium electrode coating is common: ruthenium series, iridium series, platinum series of metal oxides, specifically: ruthenium iridium, iridium tantalum, pure ruthenium, platinum-plated, platinum-iridium and other two, three or multiple precious metals mixed oxides. There is also a titanium lead dioxide coating anode, this is in titanium substrate plating lead dioxide, compared with other precious metals the price is cheaper, but there is a certain secondary pollution.
Oxygen evolution type anode and chlorine evolution type anode: generally according to the classification of gas precipitation, can be divided into oxygen evolution type anode and chlorine evolution type anode

Oxygen evolution type anode is generally used for alkaline environment media, chlorine evolution type anode is generally used for acidic environment media. Of course, sometimes there are environments where both oxygen evolution and chlorine evolution are present. Therefore, it is necessary to determine whether the ambient solution is mainly oxygen evolution or chlorine evolution to select and mix the formulation of the noble metal oxide coating (mmo).

In the selection and deployment of titanium electrode coating, should consider the specific use of medium environment, current density, groove pressure and other technological conditions and customer cost control, to meet the needs of customers. In short, the characteristics of titanium electrode and coating is that the mixed oxide coating formula can be prepared in different use environments, in order to play a good electrocatalytic activity and corrosion resistance in the process of use.
